In this paper, a compact rectangular microstrip dual frequency antenna is presented for wireless local area networks (WLAN) application in IEEE802.11a standard operating in the 2.4/5.2. The proposed design is achieved by loading two pairs of slits in the non-radiating edges. By increasing the length of the slits, the higher resonant frequencies are tuned.… (More)
Certain applications such as RFID, on body sensors network, microwave systems usually require good matching impedance, high gain and large bandwidth for their antennas. The aperture coupled antenna is one candidate that can provide high gain large bandwidth and little packaging. Thus, it would be of interest to enhance the characteristics of a singly-fed… (More)
