Specific embodiment
Because each can be taken or wireless electronic product (as mobile phone, bluetooth earphone, bluetooth wrist-watch) generally all has button, especially mainly use button (as the switch wiring etc.) that certain volume is all arranged, so can take certain space; And the purpose of this invention is to provide a kind of technology, make full use of circuit board and be located at the space that shift knob forms on the circuit board, and at circuit board when tiny and the problem that can not directly put antenna, so add an antenna (comprising unipole antenna, folded antenna or inverse-F antenna) in aforesaid space, thereby saved segment space, reached good antenna effect.
In the described antenna assembly construction for radio products, described antenna (is comprised unipole antenna, folded antenna or inverse-F antenna, join with the circuit signal end on the circuit board, and by circuit signal end joint, punishing successively to its tail end is that the antenna that L1, L2 and L3 are three sections also can prolong antenna after the L3 section, but being non-major radial, is the waste to space and material.L1 is circuit signal end and the L2 section of joining on the connecting circuit plate, three sections sums of L1, L2 and L3, and promptly total line length is 0.2 λ-0.3 λ; The L1 segment length is an antenna total length 20%; The L2 segment length equals the L3 segment length, and length all is antenna total length 40%; Three sections edges with circuit board of L1, L2 and L3 are the boundary, are located at the push-button switch periphery.The distance of L2 section and L3 section total length 50% and circuit board is more than or equal to λ/30.
Antenna is λ/4 unipole antennas or λ/4 folded antennas, or λ/4 inverse-F antennas, and major radial is single line or parallel lines, join with circuit signal end on the circuit board, and by circuit signal end joint, to the tail end of its single line or parallel lines; Major radial single line or the total line length of major radial parallel lines are 0.2 λ-0.3 λ; λ/4 unipole antenna major radials are a single line, join with circuit signal end on the circuit board, and by circuit signal end joint, to the tail end of its single line; λ/4 folded antenna major radials are a single line, join with circuit signal end on the circuit board, and by circuit signal end joint, to the tail end of its parallel lines; λ/4 inverse-F antenna major radials are a single line, join with circuit signal end on the circuit board, and by circuit signal end joint, to the longest tail end of its single line.
One highest wisdom antenna is placed on the floor, can make the floor produce a refluence electric current because of mirror effect, thereby cause a direction radiation radiation counteracting that antenna emits is weakened.So we are divided into a, b, four districts of c, d with the described circuit board of being located at around the push-button switch on the circuit board, as shown in Figure 5; The L1 of antenna (comprising unipole antenna, folded antenna or inverse-F antenna), L2 section are in a or b or c district; And the L3 section can be in a, b, any one district of c, d.
Count by the circuit board antenna outlet, incipient transmitting power is the strongest, and because antenna when on the circuit board that closely is abound with the floor, working, can produce the phenomenon of mirror images electric current electric wave, its gain loss can be very big, antenna only just can make the loss minimum of antenna gain along the circuit edges of boards, the L2 section of described antenna (promptly a section of intense radiation) can only be in a or b or c district, can not be in the d district; And the L3 section can be in a, b, any one district of c, d.The mode of detouring like this can make it minimize because of floor mirror image problem gain loss.
We can arbitrarily change the antenna outlet (being the starting end of antenna) of the mode that detours of size, conversion antenna of circuit board or direction (at most around button detour along the floor circle) translation circuit plate as requested; Now some examples of implementation shown in conjunction with the accompanying drawings are described in detail, so that can more easily understand above-mentioned and other feature, practicality and the advantage of the present invention.
We propose by zigzag antenna, button and be abound with antenna that the circuit board on floor constitutes shown in Fig. 4 A, Fig. 4 B because button is arranged in the middle of the antenna, can dwindles its antenna and take up room.This meander line antenna 1 is arranged on the front of the circuit board 3 that is abound with the floor, one button 2 is arranged in the middle of antenna and the circuit board, media 5 such as an available plastic cement or foamed glue are finalized the design between zig zag plane and circuit board, height between zig zag plane and circuit board has certain requirement, because circuit board is abound with the floor, so usually, meander line is near more from circuit board, and the antenna gain loss is just big more.Antenna height of the present invention is approximately λ/30, is lower than the frequency range that this highly then can't satisfy our needs, and antenna can reduce the loss of antenna gain like this along the ground edges of boards.According to its design feature, its current direction as shown in Figure 6, simultaneously, the minimum meander length of meander line also has certain requirement, optimum length is approximately 0.2 λ-0.3 λ.Reach the frequency that we want by the length of regulating tortuous lead, the middle button switch also can have some influence to its frequency range simultaneously, can make frequency range increase to some extent.Thereby make the size of this modular antenna little, bandwidth, the low advantage of loss is more winning.
Referring now to figure example is proposed, with the similar plastic stent of a length about quarter-wave lead of centre frequency that is antenna work and height and antenna height by processing.By shape and the height of regulating tortuous lead, position etc. can obtain the working frequency range that we will use.
Below some is relevant with antenna performance:
1, button
Antenna of the present invention is based on its basic structure, and the employing of button has certain help for the performance of antenna, because the coupling capacitance that medium produced can make Shi Mifu that circle dwindles, thereby the frequency range that order matches increases.And button is arranged in the space of antenna and circuit board, do not understand taking other spaces more.
2, circuit board
Circuit board is one to be abound with the circuit board of the radio function on floor; Size definition is that width is equal to or less than λ/8, and length is less than λ/4, and shape can change to some extent, as rectangle, oval as Fig. 6 D or irregular shape such as Fig. 6 E.One button is arranged on circuit board, the zone of below is the electronic component put area, and back of circuit board also is the electronic component put area.
3, antenna
(1) form
The present invention is based on its basic structure, the antenna outlet (being the starting end of antenna) of the size that we can be by changing circuit board, the mode that detours of conversion antenna (at most around button detour along the floor circle), the length that changes each section of antenna and shape, translation circuit plate changes the length of meander line, and the tortuous mode etc. that perhaps changes meander line derives a lot of other similar combined antennas.
(2) live width
1., antenna of the present invention can be as the structure of Fig. 4 A, Fig. 4 B, this structure demonstrates when push-button switch is positioned at zigzag antenna and circuit board middle, and the frequency range of antenna is had certain influence, can be so that antenna bandwidth broadens.
2., the structure of antenna of the present invention, its L2 section and L3 section total length 50% with the distance of circuit board more than or equal to λ/30.
(3), the mode that detours
