Comparative Analysis of K-band Crossed Slot and Crossed Dipole Antennas

Abstract

In this paper a comparison between the crossed dipole and the corresponding crossed slot antennas intended for K-band applications has been presented. The analysis of the crossed slot and dipole antennas which are complementary structures is carried out to investigate their performances focusing with two objectives: one is to study their advantages as the single radiating elements suitable for energy harvesting applications and the other is to evaluate their applicability as a radiating element in an array. Therefore, both antennas were simulated and optimized at 25.875 GHz on the same substrate with added parallel reflector plate. The simulated results are presented and discussed.
