Design and Analysis of a Novel Patch Antenna Array for 5G and Millimeter Wave Applications

Multiband high gain antennas are the essence of future wireless communication networks. This paper presents a detailed investigation and design of 1×4 linear and 2×2 planar array antennas. Arrays are designed using Rogers RT/duroid5880 (lossy) substrate. Thickness, dielectric constant and tangent loss of the substrate are 0.508 mm, 2.2 and 0.0013 respectively. Both arrays are multiband antennas and have resonance frequencies in K band, Ka band and V band. The maximum and minimum gains of 14.22 dB and 9.9 dB are achieved at 44.8 GHz and 67.8 GHz using linear array. The highest gain of planar antenna is 12.34 dB at 29 GHz and lowest gain of 8.5 dB is obtained at 38 GHz. Radiation efficiency of both antennas are in the range of 90% at all the resonance frequencies. Results of both arrays show that array with linear setup have better gain than array of planar setup whereas bandwidth and return loss of planar array is better than linear array.
