Abstract :
In this paper, a compact tri-band antenna switch module is presented. The module consists of a high rejection triplexer embedded in LTCC board and three surface mounted SPDT switches. The module operates at B3, L and S channel of Compass Satellite Positioning System. Experimental results show that the insertion loss of the switch module is less than 3.5dB and the rejection between B3 and L is more than 35dB. Well agreement between simulated and experimental result is achieved.
