low costs. Dual-band operation is an important subject in microstrip antenna designs [5,6]. Recently, several designs of the dual-band slot-loaded microstrip antennas have been reported [7{9]. These related dual-band designs are achieved by embedding a narrow arc-shaped slot or placing an open-ring slot close to the boundary of the patch [10,11]. Reconfigurable Dual-Band Patch Antenna Using Varactor-Loaded Slot microstrip patch antenna with reconfigurable dual band operation. Dual-band is achieved by the placement of a lumped capacitor on a slotted patch antenna, and the two resonant frequencies and their ratio are function of the capacitance value. Consequently, tuning of both frequencies is allowed by choosing proper capacitor value. Slot Loaded Microstrip Antenna for GPS, Wi-Fi, and WiMAX ... degenerate into a slot loaded dual band antenna [1] Here, we present the symmetric Y- and asymmetric U-shaped slots loaded tri-band compact patch antenna for wireless applications. The proposed antenna has been designed for triple band which cover the frequency band 1.561-1.589 GHz, 2.393-2.523GHz, and 3.30-3.661 GHz for GPS, Wi-Fi, and On the Use of Slots in the Design of Patch Antennas
