Compact range feed source suitable for indoor ultra-broadband wireless communication frequency band

Abstract

The invention relates to a compact field feed source suitable for an indoor ultra-broad band wireless communication frequency and is characterized in that the compact field feed source comprises a double-ridge horn antenna, a supporting column, a flange and a wave absorbing material covered on the flange; the double-ridge horn antenna is connected with the supporting column and the supporting column is connected with the flange; the wave absorbing material is connected with the upper surface of the flange and surrounds the side surface of the supporting column; the opening surface of the double-ridge horn antenna is parallel to the lower surface of the flange; the double-ridge horn antenna comprises a horn wall with a specific size, two ridges which adopt a specific ridge curve, a back wall, a short circuit board and an SMA standard joint. The compact field feed source overcomes the problem of narrower frequency band of the original standard wave band feed source, achieves the ultra-broad band communication frequency width set by the Federal Communications Commission, can greatly improve the test efficiency of a broad band system and timely finish the test on a time domain signal; moreover, the compact field feed source has the advantages of small size, light weight, low cost and high performance.

Description

technical field [0001] The invention relates to a compact field feed source suitable for indoor ultra-broadband wireless communication frequency bands, which can be used for both receiving and transmitting radio waves. It is mainly used for tight field testing. On the one hand, it can be used as a common antenna and RCS measurement feed in a tight field, and on the other hand, it can be used as a quiet zone detection feed in a tight field. In addition, the feed can also be used as a common reflector antenna feed, a terminal antenna for ultra-wideband radio equipment such as electronic reconnaissance, electronic jamming, and ground-penetrating radar, and a base station antenna for ultra-wideband communication after a certain structural modification. It belongs to the technical field of wireless communication. Background technique [0002] As the FCC-Federal Communications Commission (FCC-Federal Communications Commission) officially promulgates that the frequency of 3.1GHz-1...
