Abstract

The invention provides a spaceborne transmit-receive integrated dual-band dual circularly polarized antenna comprising antenna units and a reflecting aluminum plate. Each antenna unit comprises an upper radiation ceramic substrate and an upper high frequency radiation patch which is pasted on the upper radiation ceramic substrate and faces the upper surface of the space, wherein a circularly polarized chamfer is respectively formed at the two ends of one diagonal line of the upper high frequency radiation patch; and a lower radiation ceramic substrate and a lower low frequency radiation patch which is pasted on the lower radiation ceramic substrate and faces the upper surface of the upper radiation ceramic substrate, wherein a circularly polarized chamfer is respectively formed at the two ends of one diagonal line of the lower low frequency radiation patch, the four side surfaces of the lower radiation ceramic substrate are respectively provided with an expansion radiation band, a high frequency antenna feed needle is arranged between the upper high frequency radiation patch and the lower low frequency radiation patch, and a low frequency antenna feed needle is arranged between the lower low frequency radiation patch and the reflecting aluminum plate.

Description

technical field [0001] The invention relates to an antenna, in particular to a satellite-borne transceiver integrated dual-frequency dual-circular polarization antenna. Background technique [0002] The advantages of low cost, miniaturization, light weight and multi-satellite launch of satellites put forward higher requirements for satellite antennas. The limitations of traditional metal helical antennas in terms of volume, weight, cost and satellite envelope are becoming more and more prominent in the application of microsatellites. Microsatellites are looking forward to low-cost, small-size, high-performance spaceborne antennas. For example, the measurement and control antennas commonly used on satellites usually require beams to achieve 360-degree spherical full coverage. The current mainstream implementation method is to use two pairs of helical antennas for transmitting and receiving. In the small outer envelope space of micro-nano satellites, install With four helica...
