Abstract

A millimeter wave Grid Array Antenna for fifth generation (5G) communications is presented. The 20 cell, nearly-rhombic, 40×40 mm2 Grid Array Antenna structure is simulated and fabricated on a Rogers RT/Duroid 5880 substrate with thickness of 0.25 mm. The grid array has |S11|<-10dB for two frequency ranges in the upper 26 GHz millimeter wave band and has a percentage bandwidth and gain of 5.41% and 16.5 dBi, respectively. The antenna is compared with a Microstrip Patch Array using same substrate and dimensions.
