Minitaurized reconfigurable multiband antennas for GPS, UMTS, WiMAX & WLAN wireless applications

Abstract

In this manuscript, compact multiband antenna for four different wireless applications is presented. Two stubs which are embedded on radiating patch produces resonances for Global Positioning System (GPS) and Universal Mobile Telecommunication system (UMTS). Also, the other two resonating bands are obtained by etching two slots which produces resonances for WiMAX and WLAN bands. Antenna offers good gain and radiation pattern at operating frequencies bands. Furthermore, to control resonating bands which are obtained by means of stubs and slots, antenna is reconfigured by using 4 PIN diodes. Antenna is designed on Rogers RT Duroid5870 with compact dimensions of 20×20 mm2.
