Abstract

The ultra-wideband high-gain beam tilt-up omnidirectional antenna of the present invention includes a first broadband sub-array and a second broadband sub-array coaxially arranged on the same medium substrate, the array elements of the two sub-arrays are not equal, and the minimum array element number is 1 , the array elements are all U-shaped symmetrical oscillators, the dielectric substrate is also provided with feeding wires, the oscillators of the first broadband sub-array and the second broadband sub-array are connected to the feeding cables through the feeding wires, and are respectively connected to the first broadband. The characteristic impedances of the two sections of the feeder cables of the sub-array and the second broadband sub-array are Z01 and Z02 respectively, and the input impedances Zin1 and Zin2 of the first broadband sub-array and the second broadband sub-array are respectively equal to their feed cables. Characteristic impedance, namely: Z01=Zin1, Z02=Zin2. The ultra-wideband high-gain beam-up omnidirectional antenna of the present invention has ultra-wideband, high gain, horizontal omnidirectional, beam-uplift, high power, high efficiency, light, small and portable, simple structure, economical and durable.

Description

【Technical field】 [0001] The present invention relates to an omnidirectional antenna device and technology, in particular to a miniaturized ultra-broadband high-gain beam-up omnidirectional antenna suitable for a UAV ground control station and its technology. 【Background technique】 [0002] With the development of the aviation industry and information technology, human beings have entered the era of drones. UAVs are suitable for performing various tasks, and have the advantages of high cost performance, and have broad application prospects in both military and civilian fields. For military use, UAVs are used for map surveying, intelligence reconnaissance, battlefield surveillance, enemy attacks, relay communications, etc.; for civilian use, UAVs are used for aerial photography, logistics express and scientific exploration. At present, China is leading the world in the field of drones. Typically, drones rely on radio remote control from a ground station to perform various t...
