Description

设在移动电话内部的隐藏式天线 及具有该天线的移动电话Concealed antenna arranged inside a mobile phone and a mobile phone with the antenna

本发明涉及一种无线电移动电话，尤其涉及其内部具有一种隐藏式天线的无线电移动电话。The present invention relates to a radio mobile phone, in particular to a radio mobile phone with a hidden antenna inside.

由于通讯技术的进步及IC元件的集成化，无线电移动电话已被广泛地使用于一般民用通信系统上。请参阅图1。图1为一熟知的无线电移动电话10的外观视图。无线电移动电话10包含有一外壳18；一移动电话电路(未显示)设于外壳18内；一收话器14；一发话器16以及一天线12。无线电移动电话10通常所使用的天线12为单偶极天线，例如1/4波长，3/8波长或是可伸缩式单偶极天线。Due to the advancement of communication technology and the integration of IC components, wireless mobile phones have been widely used in general civil communication systems. See Figure 1. FIG. 1 is an external view of a known radio mobile telephone 10. As shown in FIG. The radio mobile phone 10 includes a housing 18 ; a mobile phone circuit (not shown) disposed in the housing 18 ; a receiver 14 ; a microphone 16 and an antenna 12 . The antenna 12 usually used by the radio mobile phone 10 is a single dipole antenna, such as 1/4 wavelength, 3/8 wavelength or a retractable single dipole antenna.

这些单偶极天线通常都设于无线电移动电话10的顶端，因此比较容易接收及发射无线电波。其中固定波长(如1/4波长)的单偶极天线是以一种可分离的方式设于外壳18顶端的天线座内，由于其不可伸缩及弯曲，所以比较占空间，并且不适于携带。可伸缩式单偶极天线在不用时虽然可收起来而将其隐藏于外壳18内，但由于使用无线电移动电话10时需将该天线拉出，而停机时则需将其收回至机壳内。该伸缩天线的经常性使用会在其机械接点上造成某些机械性的伤害，使得该伸缩天线在其接触点上产生不良的电性接触而影响到信号传输。These single dipole antennas are usually arranged on the top of the radio mobile phone 10, so it is easier to receive and transmit radio waves. Wherein the single dipole antenna with fixed wavelength (such as 1/4 wavelength) is arranged in a detachable manner in the antenna seat at the top of the housing 18. Since it is not stretchable and bendable, it takes up more space and is not suitable for carrying. Although the retractable single dipole antenna can be stowed and hidden in the casing 18 when not in use, the antenna needs to be pulled out when using the radio mobile phone 10, and it needs to be retracted in the casing when it is shut down. . The frequent use of the telescopic antenna will cause some mechanical damage on its mechanical contacts, so that the telescopic antenna will have poor electrical contact at its contact points and affect signal transmission.

请参阅图6。图6为无线电移动电话10单偶极天线12的场形示意图。在图6中可见该单偶极天线的散射场是向四面八方散射，所以其方向性相当差，而适用于高移动性的移动电话上。一般说来，移动电话在使用时通常会被靠在耳边，若是使用如图6所示的单偶极天线12，则向人体方向散射的散射场便会直接影响到人体。这种散射场若长期直接照射人体，有可能会对人体造成不良的影响。See Figure 6. FIG. 6 is a schematic diagram of the field shape of the single dipole antenna 12 of the radio mobile phone 10 . It can be seen in FIG. 6 that the scattered field of the single dipole antenna is scattered in all directions, so its directivity is quite poor, and it is suitable for mobile phones with high mobility. Generally speaking, a mobile phone is usually held against the ear when in use. If a single dipole antenna 12 as shown in FIG. 6 is used, the scattering field scattered toward the human body will directly affect the human body. If the scattered field directly irradiates the human body for a long time, it may cause adverse effects on the human body.

若将天线设于移动电话外壳的内部，则一方面可以缩减移动电话的体积并消除天线机械性的摩擦或接触，而另一方面则可限制电磁波发射的方向使其不直接照射人体。If the antenna is arranged inside the casing of the mobile phone, on the one hand, the volume of the mobile phone can be reduced and the mechanical friction or contact of the antenna can be eliminated;

因此，本发明的主要目的在于设计一种隐藏式天线以解决上述单偶极天线所造成的问题。Therefore, the main purpose of the present invention is to design a concealed antenna to solve the problems caused by the above-mentioned single dipole antenna.
