More particularly, the present invention relates to a hand-held device for improving the antenna radiation pattern and a radiation field type adjustment method. [Previous technical standards] With the development of wireless communication technology and the popularization of wireless communication devices, various mobile communication devices have become indispensable electronic products for modern people's lives. In addition to basic communication functions, mobile communication devices have developed many additional functions and applications, among which the global positioning system (Global Positioni.ng.. System, GPS) positioning function is most valued. [0003] In general, the signals required for GPS positioning are mainly from satellite signals. In various mobile communication devices, most of the handheld devices are used in conjunction with user habits, and the antennas disposed in the handheld devices are In order to facilitate receiving the signal of the base station, it is designed to have an omni-directional antenna light field type on the horizontal plane (xy plane), but relatively vertical (+z direction) signal receiving capability. It is weaker. Therefore, when the handheld device uses the GPS positioning function and wants to receive satellite signals from the sky direction (ie, + Z direction), it has the disadvantage of poor reception. [0004] In order to improve the shortcomings of the handheld device in the +2 direction, it is common practice to use an integrated component such as a resistor, an inductor or a capacitor to improve the impedance matching of the antenna, and to improve the impedance matching.

The first embodiment of the present invention is a hand-held device 1, a schematic view of which is depicted in Figure 1. For the convenience of the following description, the relative direction of the hand-held device 1 is first defined. Referring to FIG. 1 , in the present specification, the top direction of the hand-held device 1 is defined as + ζ direction, and the bottom direction of the hand-held device 1 is -Ζ Direction, and the hand-held device 1 is perpendicular to the xy plane, wherein the +ζ direction is in the direction toward the sky, that is, toward the satellite, and the xy plane is a plane parallel to the ground plane. The directions defined in this specification are only for the purpose of explaining the present invention. The relative orientation of the handheld device 1 depends on the actual use situation. 100112702 Form number 'A0101 Page 5 / Total 22 pages 1002021133-0 201242167 is different' is not used Limit the scope of the invention. [0014] [0014] The handheld device 1 includes a radiator 11, a guiding body 13 and a system grounding surface 15, and the guiding body 13 is disposed in the bottom direction of the radiator U (for example, the guiding body 13 can be configured or attached) Attached to an insulating carrier, that is, the -Z direction of the radiator 11 is located on one side of the system ground plane 15 and is not in contact with the light projecting body 11 and the system grounding surface 15 (ie, electrical property is not Connection), that is, the guide body 13 assumes a floating state. The guiding body 13 has a length L and is separated from the radiator U by a gap G. The radiator n, the guiding body 13 and the system grounding surface 15 are all realized by a conductive material, and the most commonly used conductive material is metallic copper. But not limited to metal copper. It should be noted that in the embodiment, the guiding body 13 is floating on one side of the system grounding surface 15. In other embodiments, the guiding body 13 can also be disposed at other positions based on the space configuration considerations, for example. It may be disposed above or below the system ground plane 15 but not in contact with the system ground plane 15, whereby the location of the director 13 is not intended to limit the scope of the present invention. The radiator 11 is configured to transmit and receive a radio frequency signal having a first current resonance path and operating at a first center frequency, the first center frequency being determined by the first current resonance path. The radiator 辐射 can be radiated at the first center frequency to form a radiation pattern and have an input impedance. In this embodiment, the radiator 11 is a printed antenna, that is, the radiator is printed on the substrate. In other embodiments, the radiator 11 can also be a three-dimensional antenna cut from a metal sheet. The implementation of the radiator is not intended to limit the scope of the invention. 100112702 Form No. 1010101 Page 6 of 22 1002021133-0 201242167 [0015] 辐射 Radiator 11 has a feed point 11a and a ground point lib, feed point 1 la and a back-end system circuit (not shown The electrical connection is used to transmit and process the RF signal, and the grounding point lib can be electrically connected to the grounding surface of the system through a through hole (Via) or a wire to provide a grounding characteristic of the radiator 11 and the feeding point 1 The position of a and the ground point lib can be adjusted depending on the actual application, and is not limited to the position shown in Fig. 1. In addition, the radiator 11 of the present embodiment is only used to exemplify an embodiment of the antenna disposed in the handheld device 1. In other embodiments, the light projecting body may also be used as a flat surface. Embodiments of an inverted-F antenna, a monopole antenna, or other antenna architecture 'radiator that can be used to transceive the radio frequency signal are not intended to limit the scope of the invention. [0016] The 〇 guiding body 13 can generate a coupi effect with the radiator 11 which can change the current distribution on the system ground plane 15 while generating an induced current on the guiding body 13. Since the radiator 11 has the first current resonance path and can radiate at the first center frequency, and the guide body 13 is only separated from the radiator 11 by a small gap g, the guide body 13 and the radiator π are correspondingly This coupling effect is produced, that is, a part of the electromagnetic field radiated by the radiator 11 is transmitted to the conductor 13', and the conductor 13 generates the induced current by the coupling effect. Since the guide body 13 has a length L, the induced current forms a second current resonance path on the guide body 13, and the second current resonance path allows the radiator body 11 to have a second center frequency. Please also refer to FIG. 2, which is a measurement diagram of the measuring radiator 11. The horizontal axis represents the frequency in units of billion hertz (GHz), and the vertical axis represents the amount 100112702.

As shown in FIG. 2, the radiator has a preferred voltage standing wave ratio at a first center frequency 2〇1 and a second center frequency 2〇2, wherein the first center frequency 201 is represented by the first current resonance path. It is determined that the second center frequency 202 is determined by the second current resonance path. Further, the second center frequency 202 can be adjusted by changing the length L of the guide body 或3 or the size of the gap 〇. Due to this coupling effect, a portion of the electromagnetic field is also transmitted to the system ground plane 15, which in turn changes the current distribution on the system ground plane 15. In particular, this coupling effect will cause the current on the system ground plane 15 to increase - in other words, more current will be distributed in the _2 direction of the radiator 11. The induced current on the conductor 13 and the increased current on the system ground plane 同样5 likewise produce radiation and can therefore be used to alter the radiation pattern of the radiator 丨丨. In detail, one of the first electromagnetic waves radiated by the radiator 11 and the second electromagnetic wave radiated by the guiding body 13 and the system ground plane 15 form constructive interference in the far field of the +z direction, that is, The first electromagnetic wave forms a superimposed effect with the second electromagnetic wave in the far field, such an effect that the radiation pattern of the radiator 11 is directed to the +2 direction, that is, the radiation pattern has a higher orientation in the +z direction. Gain (gain). As a result, the hand-held device 1 has a better signal-receiving capability in the +z direction, which helps to receive satellite signals from the +z direction. In order to understand the effect of the guide body 13 on the radiation pattern of the radiator 11, the variation of the hemisphere gain above the radiation pattern is listed below.

Please refer to Fig. 3, which is a line graph of the normalization of the upper hemisphere gain, the horizontal axis is the change of the length L of the guide body 13, the unit is millimeter (millimeter); the vertical axis is the normalized upper hemisphere gain, the unit is dB ; The figure shows the value of the normalized upper hemisphere gain for various length L values and gap G values. It can be seen from the figure that the values of the gains of the normalized upper hemispheres are all greater than 0, that is, when the guide body 13 is disposed, the hemisphere gain of the radiator 11 is higher than the hemisphere gain of the radiator 11 when the guide body 13 is not provided, and Adjusting the length L value and the gap G value adjusts the hemispherical gain above the radiator 11. The distribution of an antenna radiation pattern can be measured by directivity. For convenience of explanation, the first directivity will indicate the directivity of the radiator 11 in the +z direction when the guide 13 is not provided. The directivity of the radiator 11 in the +z direction when the guide body 13 is disposed is indicated by the second directivity. In order to clearly understand the influence of the guiding body 13 on the radiation pattern of the radiator 11, the following definition of a normalized directivity is the second directivity divided by the first directivity, and the guiding body can be known through the normalized directivity. The effect of 13 on the directivity of the radiator 11. Please refer to Fig. 4, which is a line diagram of direct normalization directivity, the horizontal axis is the change of the length L of the guide body 13, the unit is mm; the vertical axis is the positive naturalization directivity; the figure is listed in various The value of the direct normalization directivity when the L value of the different length and the G value of the gap. As can be seen from the figure, the values of the normalized directivity are all greater than 1, that is, the directivity of the radiator 11 when the guide body 13 is disposed is superior to the directivity of the radiator 11 when the guide body 13 is not provided, and the length L value is adjusted. 100112702 Form No. A0101 Page 9 of 22 1002021133-0 201242167 The gap G value adjusts the directivity of the radiator 11. [0025] [0025] 100112702 On the other hand, the gap G between the guiding body 13 and the radiator U can form a capacitance effect. The length L of the guiding body 13 can form an inductive effect, and the electric valley effect and the The inductive effect affects the input impedance value of the radiator u1. Specifically, the capacitive effect increases the electrical valley value of the input impedance of the light emitter 11 'this capacitive effect increases the input impedance of the radiator 11 The inductance value, therefore, the impedance matching of the radiator 11 can be adjusted by changing the gap G or the length l, so that the input impedance of the radiator 11 is matched to the commonly used 50 ohm (〇hm) impedance, and good impedance matching will be performed. The radiation gain of the radiator 11 can be increased. In order to see the effect of the capacitance effect and the inductance effect on the input impedance value of the radiator ,, the average gain variation of the radiator 11 can be observed, and the higher the average gain value of the radiator ^ represents the radiator. The better the impedance matching of 11 is, the better the β is. For the convenience of the following description, the average gain of the radiation pattern of the light projecting body 11 when the guiding body 13 is not provided is represented by the first average gain, which is represented by the second average gain. The average gain of the radiation pattern of the radiator 11 when the director 13 is set, and for ease of comparison, defines a positive normalization (n〇rmal ized) average enhancement as the second average gain minus the first average gain. Please refer to Fig. 5, which is a line graph of the normalized average gain, the horizontal axis is the change of the length L of the guide body 13, and the unit is mm; the vertical axis is the positive normalized average gain, and the unit is listed in the figure. The value of the normalized average gain is obtained for various lengths of 匕 and gap G values. As can be seen from the figure, the value of the normalized average gain is greater than 〇, which means that the average gain of the radiator 11 when the guide 13 is set is higher than the average form number A0101 of the radiator when the guide is not set. A total of 22 pages '1002021133-0 201242167 gain' and by adjusting the length L value and the gap G value can have different sound improvement effects. [0027] In summary, by providing the guiding body u in the -z direction of the radiator 11, the radiation field of the radiator can be directed to the +z direction, and the impedance matching of the radiator 11 can be improved. The radiator 11 has a higher flattening benefit value, and the length L and the gap G of the guiding body 13 can be appropriately adjusted, which is in accordance with the requirements in practical applications. In this embodiment, the radiator 11 is used in a global positioning system (Global Positioning Sys, tem'GPS) frequency band, and the adjustment formula of the length L is between 6 〇 mm and 65 咖, and the adjustment range of the gap G is It is between 〇mm and 5mm, but the adjustment of the length gap is different from that of the actual application. It is not limited to the above range, and the radiator is used as the frequency band. It is also not limited to the GPS band.
