Design and Analysis of Compact Printed Triple Band Antenna for Wi-Max, Wlan and Wireless Systems

In this paper, we design a compact single antenna which is used for different bands. The term compact here means that the size of the antenna is very small to the tune of just 24×30mm². This antenna is fabricated on roger RTduroid 5880 with thickness 0.79 mm, and is designed using partial ground plane. The antenna is equipped with two inverted L shaped stub and a stub of combination of inverted L shape and T shape; and it resonates at three frequencies, 2.57GHz, 3.52GHz, and 5.51GHz. As the operating range of antenna covers these frequencies, its main use is in Wi-MAX (wide interoperability for microwave access) and WLAN (wireless local area network). All the parameters and details are elaborated by the ensuing parts of this paper.
