Hexagonal Loop Microstrip Patch Antenna for Wireless Communications

This work presents a compact broad bandwidth hexagonal loop microstrip patch antenna. The proposed antenna consists of a coplanar waveguide, a hexagonal loop microstrip patch and uses the feeding way of coplanar waveguide. The proposed hexagonal radiator is cut a circular patch out the center of a hexagonal patch. That is, it called hexagon loop. The antenna is designed a very simple structure and compact size for a board bandwidth of a satellite communication. The proposed antenna obtains dual frequency bandwidths of 3.22 GHz (3.34 - 6.56 GHz) and 5.3 GHz (8.6 - 13.73 GHz). Also, the antenna obtains a realized peak gain of 9 dBi at low frequency band and 4.5 dBi - 8.6 dBi at high frequency band and generates circular polarization at high frequency band. The dimensions are 22 × 29 × 1.52 mm³. The proposed antenna covers the frequency bands of WLAN, WiMax, and other wireless applications which come under the frequency ranges of S-band, C-band, and X-band.
