Broadband bow-tie antenna for dual-band wave trapping reflector

Abstract

本发明涉及一种双频陷波反射器的宽带领结天线。该天线由领结辐射贴片(1)、馈电传输线(2)、介质基板(5)和陷波反射器(6)组成,其中两片领结辐射贴片成对跖状印制于介质基板(5)的两面,分别与馈电传输线的导带(3)和地(4)在传输线末端(10)相连。陷波反射器(6)由两段长度不等的终端开路的左边微带开路线(11)和右边微带开路线(12)构成,其导带和地在陷波反射器的第一加载点(9)和第二加载点(13)分别与馈电传输线的导带(3)和地(4)相连。该天线的陷波反射器,在天线的工作频段内可提高天线增益,同时在低于工作频段的两个陷波频段内可作为滤波器,抑制天线的辐射。
The invention relates to a broadband bow-tie antenna for a dual-band wave trapping reflector. The antenna is composed of bow-tie radiation patches (1), a feed transmission line (2), a medium substrate (5) and a wave trapping reflector (6), wherein the two pieces of bow-tie radiation patches are pairwise printed on the two sides of the medium substrate, and respectively connected to a conduction band (3) of the feed transmission line and the ground (4) at tail end (10) of the transmission line. The wave trapping reflector (6) is composed of a left micro-strip open-circuit line (11) and a right micro-strip open-circuit line (12) which are terminal open-circuits with different length, the conduction band and the ground wire of the wave trapping reflector are respectively connected to the conduction band (3) of the feed transmission line and the ground (4) at a first loading point (9) and a second loading point (13) of the wave trapping reflector. The wave trapping reflector of the antenna can improve antenna gain within the working frequency band of the antenna, and meanwhile, also can be used as a filter within two wave trapping frequency bands lower than the working frequency band for restraining radiation of the antenna.
