Design of a Millimeter Wave Microstrip Patch Antenna and Its Array for 5G Applications

Abstract

A millimeter wave microstrip patch antenna and its array for 5G applications is proposed. The 5G Microstrip patch is designed on rogers RT Duroid 5880 substrate with standard thickness 0.787 mm having relative dielectric constant (ϵ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">r</sub> ) = 2.2 and tan δ = 0.0013. The antenna resonates at 24.85 GHz with a return loss -19.5 dB and a bandwidth 1.318 GHz. An array of 1x4 element of the proposed antenna is designed using tapered line feeding. The antenna array resonants at four different frequencies i.e. 23.2 GHz, 27.09 GHz, 31 GHz and 42.5 GHz. Appreciable improvement in gain is observed with the array of antennas. The antenna and its array can be used for 5G mobile communication because of its compactness.
