A 30-Pointed Star-Shaped Patch Wideband Antenna for WLAN and WiMAX Applications

Wideband microstrip antenna is required in modern wireless communication. Microstrip antenna has the characteristic of being lightweight, small in size, and easy-to-integrate. Due to the need for wideband antennas, many types of antenna patches have been developed over the years. In this work, a novel antenna of a 30-pointed star-shaped patch was designed to operate in WLAN and WiMAX bands and fabricated on an FR-4 substrate. The antenna bandwidths are 4.5 GHz in simulation and multiband of 0.9312 GHz and 2.946 GHz in measurement. Both simulation and measurement bandwidths cover the WLAN and WiMAX frequency bands.
