Tri Pentagon Slotted Antenna Using Jeans Material WLAN/Hiper LAN Application

Recently the thinner and lighter devices are preferred by the consumers because of having multifunctional capabilities. That's why dual-band antennas for WLAN and Hiper LAN applications are developed to fulfill the demand of consumers. A new compact antenna operating in 2 to 11 GHz frequency range has been presented in this paper. The design is planned for the Hiper LAN and WLAN applications. The simulations of the antenna in free space produced desired results in terms of gain, radiation efficiency, and bandwidth; a maximum directivity of 4.372 dB was achieved. A slotted circular patch with line feed is made on substrate having partial ground plane of copper. The presented antenna gives dual band width of 31.84% and 87.85%.
