Design and Simulation of a Multiband Millimeter Wave Microstrip Patch Antenna Array for 5G Wireless Communication

In this paper, a 2x2 multiband patch antenna array is presented and it is designed and simulated by using CST Microwave Studio for the bands 24GHz-27GHz, 31-34GHz, 42GHz-48GHz, 50GHz-52GHz, 65GHz 68GHz, 82GHz-85GHz. The design of patch antennas is very efficient and widely used in wireless communication due to their lower cost of fabrication, light weight and can operate a microwave frequency but it offers low efficiency, low gain etc. Future upcoming 5G wireless communication is needed of high gain, good protection from path loss because of their millimeter wavelength, broadband performances of antennas. Similarly, the multiband antennas are highly desired to use a single antenna instead of multiple antennas for different bands. The antenna provides maximum and minimum gains of 15.63dB and 9.23dB at operating frequency 26.82 GHz and 34.60 GHz. The radiation efficiency is achieved 96% and above for all operating frequencies, total bandwidth of 11.84 GHz. The overall size of antenna is 20.66mmX22.56mmX0.67mm make it normed to work better by fulfilling the requirements for 5G communication.
