Radome Design with Improved Aerodynamics and Radiation for Smart Antennas in Automotive Applications

More applications are using wireless communication, where the radomes become more important as they are essential in the performance of antennas as well as protect antennas from environmental conditions. The focus in this study is to design a radome for a customized smart antenna such that the attenuation of antenna signal and the increase in drag coefficient of vehicle are minimized. This paper presents a novel method of radome design and the simulation results demonstrate that the drag coefficient of the vehicle is slightly increased by less than 2% while the loss to the signal strength is less than 0.5 dB.
