摘要

In this research, the polarization and bandwidth of a zeroth-order resonators(ZORs) loaded microstrip antenna are improved by employing a grid polarizationfilter cover and a metallic cavity. The polarization improvement is owingto three operations, (a) the filter cover allows co-polarization wave passingthrough only, (b) the ZORs partly rotate the reflected cross-polarizations(X-polarizations) wave to be co-polarization, (c) the metallic cavity suppressesthe fringe fields of the cover. The bandwidth enhancement is owing to thepolarization cover that reflects the X-polarization, which forms a resonant cavity.The improvements of the simulated cross-polarizations range from 17.7 to35.3 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 proposedantenna. The measured results verify the simulations.
