Design and Analysis of Dual-Band Microstrip Patch Antenna Array for 5G Cellular Communication Networks with Improved Radiation Characteristics

With the advancement of world to 5
^th
Generation cellular communication system presently commercial implementation of 5G in USA, UK, Switzerland, South Korea and Spain a space for improvement of radiation characteristics is always there for Antenna to accommodate the high gain demands of 5G. In this paper the design and simulation of compact, millimeter wave antenna array for 5G wireless communication network is proposed operating at 30 GHz and 50 GHz. Ka band from 26GHz to 42 GHz and V band from 40GHz to 75GHz need dual band frequency for its application from a single antenna. A conventional patch antenna with dimension 3×3 mm

is designed on Rogers RT5880LZ substrate material with thickness of 0.787 mm. Two Rectangular and one circular slot is made in the patch to attain another band at 50 GHz frequency. In this proposed antenna array configuration of 2×1 met the requirement s of improved radiation characteristics. In this proposed antenna array configuration meets the commercial demands such as 75 ohm coax cable and substrate material with thickness of 0.787mm. The realized gain of 10.2 dB & 11.6 dB and return loss value of -12.5 & -14.85 at 30 GHz and 50 GHz respectively is achieved. The bandwidth is 2.093 GHz and 1.764 GHz at 30GHz and 50GHz Respectively. The VSWR value measured from simulation is 1.67 and 1.43 at dual bands frequency which is less than 2. The proposed antenna is fed by corporate feed network technique.
