A Reconfigurable 28/38 GHz Omni-directional Antenna Design for Future 5G Applications

This paper presents a simple and compact reconfigurable monopole omni-directional antenna operating at 28 and 38GHz for 6G applications. The proposed antenna has a wideband with dual-band operating characteristics. Two monopole antennas are printed on a substrate and connected through a PIN diode to achieve a dual-band operation. By changing the biasing of the PIN diode, different operational frequencies 28GHz and 38GHz bands are achieved. The proposed antenna is simulated using two different electromagnetic solvers, where an excellent agreement between both simulated results is achieved.
