Abstract A tapered slot antenna integrated with metamaterial unit cells and dielectric loading is proposed in this paper. The impedance bandwidth is 27-29 GHz (7.2%) with a forward gain of 12 dBi and a high aperture efficiency of 75%. In order to achieve uniform received power on the ground, antenna elements with 3 dB higher gain are necessary for beams oriented at ±45°, hence a compact co-polarized topology of pattern diversity is proposed to achieve a wide angle coverage of ±65° with path loss compensation. Detailed simulation and measurement results are presented.
