Design of a Microstrip Open Loop Resonator BPF with Wide Stopband for WLAN

A new microstrip open loop resonator bandpass filter (BPF) for wireless local area networks (WLAN) with a wide stopband response is presented in this article. The BPF consists of a pair of λ/2 open loop resonators and two additional resonators ope...
RF and microwave microstrip BPFs with high selectivity, low insertion loss, suppression of spurious sideband and wide stopband are widely used in recent wireless communication systems. 1 In 2002, the IEEE extended the 802.11b standard in the 2.4 to 2.4835 GHz frequency range; the fast development of WLAN communications...
