摘要：In this rapid changing world in wireless communication systems, multiband antenna has been playing a very important role for wireless service requirements. Rectangular line slot designs of a dual band patch antenna have been investigated in this paper. By using rectangular line slot patch geometry dual band operation has been obtained. The patch antenna is simulated by Ansoft HFSS and antenna magus software which is finite element method based simulators. After the antenna performance characteristics such as, input impedance, return loss, polar plot are obtained.. This ob servation has provided us sufficient insight to optimize the antennaparameters to meet the design requirements. The proposed designs of the antenna operate in 2.4 GHz band which is common to all two designs but the second operating band is different. By varying the slot broadness the second frequency band can be shifted.IEEE802.11b (2.45 GHz), IEEE802.11y (3.2 GHz) andIEEE802.11a(5.775 GHz) standards which would allow WLAN operation. This patch antenna has been intended to be used in portable devices that demand miniaturized constituent parts.
