Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments, is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of metal 5CA antennas based under small headroom as shown in figures 1 to 6, including metal edge frame
Antenna 3, the metal edge frame antenna 3 are arranged between comprehensive screen 1 and complete machine metal outer frame 2, the periphery of comprehensive screen 1
Edge is equipped with complete machine metal outer frame 2, and a part of the metal edge frame antenna 3 using metal edge frame as antenna is radiated,
The back of comprehensive screen 1 is equipped with pcb board 7；
In this in-kind simulation, double-layer PCB board 7 is used, antenna motherboard size is 145mm*76mm*1mm, and substrate is
FR4 (δ=0.024 ε=4.3), the top edge of the pcb board 7 passes sequentially through feeding point 6, first antenna coordinates switch 5 and second
Its line coordination switch 8 is connect with the complete machine metal outer frame 2 of the top edge of comprehensive screen 1, centered on feeding point 6, passes through second
Its line coordination switch 9 is added inductance and generates second low frequency+intermediate frequency+harmonic high frequency in the case where first antenna coordinates switch 5open state
Vibration includes Band 1Band2 Band3 Band4 Band5 Band34 Band39 Band40 Band41 Band7, in addition,
Reach in 820MHz~960MHz~1710MHz~2170MHz/2300MHz~2700MHz frequency range internal antenna radiation efficiency
It is poly- to can be realized 5 LTE frequency range carrier waves such as Band5+Band40+Band39+Band41+Band7 substantially by 35%-40% or more
