Design and Performance Evaluation of Frequency Reconfigurable Antenna for 5G Wireless Communication Applications

A reconfigurable antenna has become a vital element in modern communication systems to meet the requirements of 5G networks such as high rate and large capacity, also to do multi-functions in one device. The target of this paper is to design a frequency reconfigurable antenna with microstrip technology to operate over 5G bands. The researchers proposed antenna which is designed on FR-4 substrate where the dielectric constant is 4.4 as for the thickness and loss tangent are 0.8mm, and 0.02 respectively. Three switches are employed to achieve the reconfigurabilty of the proposed antenna. Based on the three states of switches, the researchers evaluated the performance of the designed antenna that included different parameters i.e., return loss, gain, and radiation efficiency, the proposed antenna has a ability to cover a frequency range of 34.02-73.04 GHz, and its gain varied between 2.1 to 5.8 GHz. Therefore, it can be used properly for 5G networks.
