“…Presently, wireless communication systems like wireless code division multiple access (WCDMA), mobile communication systems (GSM, CDMA, WCDMA, TD-SCDMA), and especially IEEE standards for wireless networks such as WLANs IEEE 802.11g and IEEE 802.11b that operate at 2.4 GHz frequency; and products of IEEE 802.11a operate at 5.8 GHz frequency [1,2], the communication systems with short range such as UWB and Bluetooth, which provide suitable communication services in modernistic society. The compact equipment which support multimode wireless systems are attractive and will be openly applied in the future [3,4]. Besides simple designed realization, low pass-band insertion loss, high selectivity, the requisite requirement of band-pass filters for wireless communication systems is large stopband characteristics and a consolidated size this is substantial in new generation of wireless communication systems.…”
