A Penta Band Slot Loaded Circular Microstrip Antenna for WLAN and WiMAX Applications
In this paper, the authors present the design and development of slot loaded circular microstrip antenna for penta band operation. The penta band antenna has been realized by incorporating plus type equal arm length slots at the center of the conventional circular microstrip antenna. The proposed antenna is operating between the frequencies range from 2.57 GHz to 11.09 GHz, covering the application bands of WLAN and WiMAX. The antenna gives broadside radiation characteristics at each operating band. The presented antennas are simulated and are analyzed using commercial ElectroMagnetic (EM) HFSS simulation software.
