Meta Surface Inspired Compact CPW Antenna for 5G Wireless Communication

A Single Complementary Slotted Ring Resonator (CSRR) based Co-Planar Waveguide (CPW) antenna operating between 3.4 - 4 GHz is presented in this article. The proposed CSRR inspired antenna is printed on 1.6 mm thick widely used FR4 substrate. As communication technology advances and 5G telecommunications become more widespread, there has been an increase in the need for antennas that are economical, thin, compact, and broad-band in frequency range. In light of this, the research presented here proposes an antenna that is inspired by metamaterials and has operating frequencies that encompass the 5G operating bands. The antenna achieves overall efficiency up to 88–90% with substantial gain around 2.8 - 3.2 dBi in the desired spectrum of operation. Besides, the antenna has omnidirectional radiation pattern which helps to cover all ranges around 5G devices. The results evident that the antenna proposed in this research could be a right contender for future 5G cellular communications.
