- Abstract
In this research, the polarization and bandwidth of a zeroth‐order resonators (ZORs) loaded microstrip antenna are improved by employing a grid polarization filter cover and a metallic cavity. The polarization improvement is owing to three operations, (a) the filter cover allows co‐polarization wave passing through only, (b) the ZORs partly rotate the reflected cross‐polarizations (X‐polarizations) wave to be co‐polarization, (c) the metallic cavity suppresses the fringe fields of the cover. The bandwidth enhancement is owing to the polarization cover that reflects the X‐polarization, which forms a resonant cavity. The improvements of the simulated cross‐polarizations range from 17.7 to 35.3 dB in the band. The measured bandwidth is increased from 940 MHz (17.22%) of the referenced antenna to 1390 MHz (24.5%) of the proposed antenna. The measured results verify the simulations.
