Abstract: With rapid evolution of wireless communication and mobile networking techniques, one of the major advancements is that fifth generation (5G) is envisioned in-order to meet the perpetual demand for greater network speed and capacity. This paper provides an overview of the design of five reconfigurable antennas for 5G wireless application is introduced by varying the substrate material used. Teflon, Taconic TLY, Rogers Ultralam 1217, Rogers RT/Duroid 5880, FR4 are the substrate materials used in designing the respective antennas. The proposed antenna designs employ a leaky-wave antenna based on half-mode substrate integrated waveguide. Since this antenna is used in 5G communication systems, the centre frequency is taken as 28.5 GHz. The length width and height of each of the antennas are designed using design procedures of rectangular patch antenna for all five substrates respectively. Each antennas are compared based on their return loss, VSWR, gain, directivity and radiation pattern respectively and an inference regarding performance of each substrate is obtained. On comparing the results of all the five antennas in the ON and OFF condition of switch, the results are found to be best in case of Rogers RT/duroid 5880 with return loss of -15.2719dB, VSWR of 1.4165, gain of 4.6dB, directivity of 4.31dB in the ON condition and with a return loss of - 13.0779dB, VSWR of 1.6893, gain of 3.4dB and directivity of 3.7dB in the OFF condition. Further by changing the switches and replaced it by conducting sheet switches for reduction of loss and were able to achieve improved results with return loss of24.5026dB, gain of 5.1dB in the ON condition and return loss of -12.6608dB and gain of 3.8dB in the OFF condition which contributed to the novelty of the project. In the proposed antennas, beam steering is obtained due to the disturbances in surface current under the influence of changing voltage bias of the switches. The technologies used make the antenna design compact provides configurability, which makes this antenna a suitable candidate for 5G applications.
