A Novel High Gain Array Antenna Design for Autonomous Vehicles of 6G Wireless Systems

By 2030, 6G wireless networks will provide a fully autonomous system for many applications, one of them is fully automated vehicles. Antennas with different gains, half-power beamwidths (HPBW), and different radiation zones will be needed for different purposes such as parking assistance, lane change, emergency braking, and traffic jam assist in autonomous vehicles with integrated RADAR technologies. The Federal Communication Commission (FCC) has proposed millimeter-wave (mmW) frequency bands for vehicular RADAR systems. This paper describes the development of a new and improved 2x4 array antenna for autonomous vehicles. Development of proto-type single patch for the array is described in [1]. The array antenna resonates at7 7 GHz frequency. With a higher gain, the optimized array antenna has a lower mutual coupling effect. The gain of the 2x4 corporate feed array antenna is 18.0 dB. The return loss was calculated to be -39.8947 decibels. The array antenna designed and described in the paper can be used in autonomous vehicles.
