Three-dimensional embattled miniaturization self-adaptation satellite navigation antenna

Abstract

A three-dimensional embattled miniaturization self-adaptation satellite navigation antenna comprises an antenna main array element, a main array element floor, a main array element array element feeder line, a main array element support, an antenna auxiliary array element, an auxiliary array element through connection floor, an auxiliary array element feeder line, an array floor, a main array element transmission network printed board, a main array element transmission network box, a main array element socket, an auxiliary array element transmission network printed board, an auxiliary array element transmission network box and an auxiliary array element socket. The three-dimensional embattled miniaturization self-adaptation satellite navigation antenna enables three-dimensional embattled design to be carried out on an antenna array element and reduces same frequency range coupling interference between the main array element and the auxiliary array element and between auxiliary array elements while meeting miniaturization requirements. Compared with a common plane multi-array element self-adaptation antenna, the three-dimensional embattled design promotes various electrical property indexes of the main array element, guarantees self-adaptation zero-setting performance of the auxiliary array element, and is applicable to miniaturization self-adaptation satellite navigation equipment.

Description

technical field [0001] The invention belongs to a satellite navigation and positioning system, in particular to a front-end antenna suitable for a miniaturized self-adaptive navigation system. Background technique [0002] The adaptive satellite navigation antenna is a kind of smart antenna, which can adjust the antenna pattern in real time, form a null in the interference direction, and realize airspace filtering, so as to ensure the transmission and reception of antenna signals. According to the working principle of the adaptive antenna, an N-element array has N-1 degrees of freedom and can resist interference from N-1 different directions at most. The increase in the number of array elements provides the possibility to improve the signal-to-noise ratio, but at the same time increases the complexity, volume and cost of the array. In actual design, a compromise between these two factors should be taken into consideration. [0003] The array elements constituting the adapt...
