Design of a Dual-Band Patch Antenna Array for Automotive and Industrial Applications

This paper proposes a novel dual-band patch antenna array for automotive and industrial applications. The element is composed of a hairpin resonator, a U-slot resonator in the ground and a radiation patch from bottom to top, which can be used to realize dual-band operation. To further improve the impedance matching and gain characteristics, a new wideband power divider is employed. Finally, a 2 × ...
