Abstract

In this paper, a tri-band-pass filter suitable for microwave applications is presented. The proposed band pass filter consists of four rectangular patches (cells) separated by four rectangular slots. The selectivity of the pass bands is adjusted by adjusting the position of transmission zeros (TZs). The locations of the TZs can be adjusted for different selectivity of the filter, by adjusting the dimensions of the rectangular cells. Also, the band pass filter's centre frequency and bandwidth of the tri pass bands are independently adjusted by changing the length and width between pass band edges, which makes the design very simple. Measured results merely agree with the simulated values.
