Compact Partial Ground Plane 1x2 Patch Antennas

In this paper a 1x2 Compact Wide-band Rectangular Patch Antenna is proposed. The antennas are designed for the IEEE 802.16a (5GHz to 6GHz) and 802.16b (2GHz to 11GHz) frequency band. A partial ground plane is loaded at feeding point to introduce additional reactance which results in wideband response. Compact size is achieved by transforming dipole antenna to monopole antennas. The-10dB impedance bandwidth of antenna is 50%. To reduce the mutual coupling mushroom type Electronic Band-gap Structure (EBG) is designed and incorporate in between the two common ground plane rectangular patch. Antennas are placed four times closer than minimum required separation. The size reduction of the antenna is more than 80%. Proposed techniques are implemented on rectangular, circular and triangular shape patches. Proposed antenna is simulated using HFSS-13.
