Rectangular Patch Antenna Performances Improvement Employing Slotted Rectangular Shaped for WLAN Applications
Recently, there has been a growing demand of microwave, and wireless communication systems in various applications resulting in an interest to improve antenna performances. Modern communication systems and instruments such as Wireless Local Area Networks (WLAN), mobile handsets require lightweight, small size and low cost. The selection of microstrip antenna technology can fulfill these requirements. WLAN in the 2.4 GHz band (2.4-2.483 GHz) has made rapid progress and several IEEE standards are available namely 802.11a, b, g and j. Various design techniques using Defected Ground structure (DGS) in the patch antenna have been suggested in previous publications. DGS is realized by etching a defect in the ground plane of planar circuits and antennas.
