In this work, a cavity-backed slot antenna has been designed to cover vehicle-to-everything (V2X) frequencies (5.85−5.9255.85-5.925 GHz). The antenna is made to be easily integrated in a vehicle windshield or rear mirror. The cavity-backed slot antenna does not require a ground plane to sit on which makes it an ideal model for below horizon performance. Antenna simulation has been done using high-frequency structure simulator (HFSS) and then on-foam and on vehicle's windshield measurements have

The proposed antenna achieved a linear average gain (LAG) above 2.5 dBi in the targeted V2X elevation and azimuth angles with better than 15 dB return loss. The antenna performance has been reported in terms of reflection coefficient, surface current density, radiation pattern, LAG, and efficiency.
