Pattern Reconfigurable Two Element Printed Patch Antenna for THz Wireless Applications

In this paper, pattern reconfigurable two element patch antenna is presented at 0.6THz frequency. Both the patch elements are fed from the common feed line and each patch element is fed from each of the corner of feed line to achieve proper impedance matching for both the patch elements. Switches (PIN diodes) are used to control reconfigurable characteristics. The purpose of this work is to achieve pattern re-configurability at THz frequency by using patch antenna. The result shows that it can divert its pattern in two different directions i.e. 26° and -26° dependent on the configuration of switches. Directivity and gain of the proposed model is 7.1 dBi and 6.9 dB respectively with radiation efficiency of 97%. The antenna has a wider bandwidth of 54.6GHz.
