This paper presents triple band notched ultra wide band (UWB) monopole antenna with overall size of 36 × 32 mm fed by microstrip transmission line. In order to achieve a good impedance matching from 2.7 GHz to 13.4 GHz, a tapered transition between the rectangular patch and the feeding line is utilized. The three notched frequency bands are accomplished by a defected microstrip structure (DMS) ...

Due to the progression growth of multiservice wireless communication systems in a single device, multiband bandpass filter has attract great attention end user. Therefore, is crucial component transceivers which can support multiple services one device. This paper presents design dual-band at 2.4 GHz and 3.5 for WLAN WiMAX applications. Firstly, wideband designed center frequency 3 based on qua...
