A Penta Band Slot Loaded Circular Microstrip Antenna for WLAN and WiMAX Applications
This paper presents the design and development of slot loaded circular microstrip antenna for penta band operation. Thepenta band antenna has been realised by incorporating plus type equal arm length slots at the centre 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 analysed using commercial electromagnetic (EM) HFSS simulation software. The experimental and simulation results are given and are discussed in this paper. A close agreement is obtained between the simulated and experimental results.
