Vehicular mm-Wave Array for Smart Handover

Abstract

[EN] The emergence of new technologies such as autonomous vehicles and high data rate 5G networks requires advanced antenna types that are capable of fulfilling requirements for highly demanding wireless communication links. The array of microstrip-fed slot-coupled patches is one such type of antenna that provides low return loss and good transient behaviour for broadband applications. A compact size slot-coupled patch antenna subarray and its phased array is proposed in this paper. Two different substrates Rogers TMM4 and Green TapeTM 951 Low Temperature Co-Fired Ceramic (LTCC) are considered for the fabrication of microstrip feedline. The feedline is fabricated on the respective substrates and then mounted on a Rogers RT/duroid 5880 laminate. Ground planes are used on both the front and backside of the antenna array. The antenna is operating in a range of 24.25 GHz - 29.5 GHz. A Smart Array is proposed in this paper which has a good performance in terms of antenna gain and scanning property for 5G application in Smart handovers.
