Abstract

Two patch resonator filters, namely Type I and Type II, are designed using a slot composed of multiple circular sectors. The filters operate in the 2.4-2.48 GHz wireless local area network (WLAN) frequency. The measured 3 dB insertion loss bandwidth of the filters covers the whole WLAN band. The stopband of the Type II filter is below 2.18 GHz and above 2.76 GHz, with a rejection of more than 20 dB. The total size of the Type II filter is 21.9 mm × 22.5 mm.
