Abstract: A novel antipodal Vivaldi antenna (AVA) array is proposed for 5G mm Wave applications.The proposed AVA array consists of 1x4 antenna elements and with dimensions 55.3x26.6x0.79mm 3 .The antenna is designed using Rogers RT/duroid 5880 material having dielectric constant 2.2 and presented material have low dielectric losses and is suitable for high frequencies.Rhombus parasitic patches, triangular corrugations at edges, and air vias are used in antenna feed line design for improvement of gain, bandwidth, and low radiation losses.The proposed antenna is operating from 25 GHz-32 GHz frequency range and antenna is resonating at 28.56 GHz.Gain is varying from 9.45 to 14.88 dBi and 95% radiation efficiency is obtained in specified frequency band.At resonant frequency 28.56 GHz front to back ratio (FBR) is 34.47dB is obtained.The proposed antenna is designed using ansys HFSS tool.
