In this article, a compact microstrip tri‐band bandpass filter based on a rectangular ring resonator (RRR) and two triangular patch resonators is presented. This filter is designed to operate at 3.5, 5.2, and 8 GHz for WiMAX, wireless local area network (WLAN), and satellite applications respectively. Also, the center frequencies of the first and second passband can be flexibly controlled by tuning the dimensions of RRR. The fabricated triband band pass filter has merits of compact size, low insertion loss, and suitable stopband. Good agreement between simulated and measured results is observed.
