摘要

A Ka-band dual-polarized low profile magneto-electric (ME) dipole antenna with wide operational bandwidth is proposed in this paper. A thin substrate with two-stage meandered vias is utilized for realization of the proposed antenna. The meandered vias aid in compensation of phase difference caused due to utilization of thin substrate. The thickness of proposed antenna is reduced from 0.25\lambda {g} to 0.11\lambda {g} by using these two-stage meandered vias. The low profile antenna topology results in bandwidth reduction which is neutralized by introducing asymmetric slots in the ground plane. Shorting pins are inserted for elimination of higher order TM21 mode of Ka-band that results in a uniform broadside radiation pattern due to excitation of fundamental TM10 mode. The proposed antenna covers whole Ka-band with operating frequencies from 26-42 GHz. A 1\times4 antenna array is also designed and fabricated with a reasonable gain of 12.06 dBi and stable radiation patterns. Simulated and measurement results are presented with detailed justification.
