A Novel Microstrip Antenna to Enhance The Bandwidth for WIFI/ WIMAX Applications
In this paper, a multiband micro strip patch antenna design has been introduced which is a novel symmetric director slotted patch. This patch antenna is designed on substrate of FR4 having permittivity of 4.4.The thickness used for substrate is 1.6mm. The unique slot design and partial ground techniques enhances the bandwidth for 5.5 GHz application. The design results in multiple resonant frequencies which include Bluetooth, Wi-Fi/WiMAX and X-band applications. Using High Frequency Structure Simulator (HFSS) software package, the antenna is simulated and dimensions are adjusted to achieve the desired resonant frequencies for multiband operation.
