The impedance of parallel strips, a quarter impedance transformer principle in applied microwave principle, guarantees the feeder line at radiating element
Impedance is 50 ohm, is connected at feeding point with 50 ohm coaxial wire bondings first, is divided into two 100 ohm of two-sided parallel strips, then
Feeder line is converted by a quarter impedance, makes feeder line 50 ohm of impedance at each radiating element feed mouth.
Additionally, it is provided a kind of ground telemetering and remote-control integral antenna platform, including tripod turntable, and it is placed in tripod
Foregoing ground telemetering and remote-control integral antenna, carry out automatically tracking communication on turntable.
The present invention can be applied particularly to unmanned plane.It is provided according to Ministry of Industry and Information, China, the use of push-button aircraft system
Frequency range plans 840.5- according to Radio Frequency Allocation Regulation of the People's Republic of China and China's frequency spectrum service condition
845MHz, 1430-1444MHz and 2408-2440MHz frequency range are used for push-button aircraft system.But 840MHz frequency and
The upstream frequency of telecommunications is overlapped, and 2400MHz and WIFI, bluetooth frequencies are overlapped.Under the two frequency ranges, unmanned aerial vehicle station is received
Machine is highly susceptible to the interference of periphery electromagnetic environment.And 1400MHz frequency is not occupied by commercial communication also nearby, it is also unallocated to give
Other application, so 840MHz emits for ground remote control, 1400MHz frequency has huge applied to unmanned aerial vehicle telemetry receiving
Big potentiality.
The second radiating element is emulated, the unmanned plane frequency range for keeping its resonance frequency covering 1400MHz legal, radiating element length
Equivalent about half wavelength, covers copper radiation minor matters in second medium plate top and bottom；Similarly emulating the first radiating element makes its resonance
The radiation minor matters of frequency coverage 840MHz equally cover copper radiation minor matters in first medium plate top and bottom.
If Fig. 4 and Fig. 5 are the standing-wave ratio analogous diagram of telecontrol antenna and telemetering antenna respectively, standing-wave ratio (SWR) full name is electricity
It presses standing-wave ratio (VSWR).In the radio communication, the impedance of the impedance mismatch or antenna and sender of antenna and feeder line is not
Match, high-frequency energy will generate back wave in antenna, and back wave and incidence wave converge generation standing wave in antenna-feeder system.In order to characterize
With the stationary wave characteristic in measurement antenna-feeder system, that is, forward wave and the case where back wave in antenna, establish " standing-wave ratio " this
One concept, actually there is always reflections, so standing-wave ratio is always greater than 1.Standing-wave ratio is to examine the foundation of feeder line efficiency of transmission,
Voltage standing wave ratio is less than 1.5.Voltage standing wave ratio is excessive, will shorten communication distance, and reflection power will return to power amplifier in transmitter portion
Point, it is easy to burn out power tube, influences communication system normal work.From Figure 4 and 5 as it can be seen that the antenna of telecontrol antenna and telemetering antenna
Standing wave meets the unmanned plane frequency range of Ministry of Industry and Information's delimitation all in 1.5dB or so, also can satisfy Unmanned Aerial Vehicle Data Link signal
It uses.
Fig. 6 and Fig. 7 is the beneficial directional diagram of telecontrol antenna and telemetering antenna, it is seen that telecontrol antenna uses 4 array elements, and gain is reachable
10dBi, the 24 array element highests that telemetering antenna uses can achieve the gain of 18dBi.If any other system requirements more high-gain,
The solution of the present invention can be used, further promote antenna gain by increasing array element quantity.
The above description is only an embodiment of the present invention, and it is not intended to limit the protection scope of the present invention, all to utilize the present invention
Equivalent structure transformation made by specification and accompanying drawing content, is applied directly or indirectly in other relevant technical fields, and wraps
It includes in scope of patent protection of the invention.
