Solar battery based conformal antenna and wing and solar power air vehicle

Abstract

The invention provides a solar battery based conformal antenna. The solar battery based conformal antenna includes an antenna block, an isolation board and a feed block. The antenna block is formed bysplicing a plurality of small solar battery panel together and the lower surface of the antenna block is made of metal and is adhered to the upper surface of an upper skin. The isolation board and the feed block are disposed between the upper skin and a lower skin. The antenna block includes an antenna radiation unit, a sender and a peripheral parasitic area. The sender is composed of parallel rectangles in cascaded connection. The peripheral parasitic area surrounds the antenna radiation unit and the sender. The isolation board covers the feed block between the upper skin and the isolation board. The feed block feeds the antenna block. The invention also provides a wing provided with the above conformal antenna. The invention also provides a solar power air vehicle provided with the above wings. The invention has advantages that high coverage rate of the solar panels is ensured since an integral design integrating the antenna and the solar battery panel is realized; and the antenna processing and manufacture difficulty is reduced since the antenna can be formed by splicing the small pieces of solar battery panels together.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a horizontally polarized end-fire antenna integrated with a carrier of a modern solar-powered aircraft. Background technique [0002] With the advancement of science and technology, solar-powered aircraft has developed rapidly. Solar electromagnetic panels are mainly laid on the upper surface of the aircraft to obtain energy and provide kinetic energy for the aircraft. In order to realize the multi-functionality of the aircraft, equipment such as radar and large sensors are equipped on the aircraft. However, the traditional antenna is directly welded to the carrier shell, which has a high profile and is easily damaged; or it is directly hung on the carrier, which affects the starting shape of the aircraft, increases resistance, and reduces flight performance. [0003] In order to solve the above problems, conformal antennas and their arrays have emerged. For examp...

Problems solved by technology

For example, "A Low-profile Conformal Antenna" proposed by Guo Lin (application number: CN 201610441467.9), but the main radiation direction of the conformal antenna array is side-firing, which cannot provide the working mode of the end-firing direction; Guo Lin proposed another An article "A High-Gain End-Fire Conformal Antenna" (application number: CN201510745761.4), although the conformal antenna can achieve high-gain end-fire mode, the carrier of the antenna must be a non-metallic carrier, and the antenna form will As a result, the area of ​​solar cells that can be laid is greatly reduced, sacrificing the kinetic energy supply of the aircraft

Zhou Jinzhu proposed "Structure-Function Integrated Wing Antenna" (authorization number: CN 103887605 B), but the antenna is placed inside the wing. If solar panels are laid on the surface of the aircraft, the design of the conformal antenna array will not work properly. , not applicable to solar vehicle carrier
