摘要

In this paper, a metrological analysis of GPS ceramic antenna using polarization conversion with anti-jamming features have been presented. Additionally, a novel polarization conversion technique using a metasurface is introduced to enhance the gain of a rectangular dielectric resonator antenna (RDRA). Two split-ring resonators (SRRs) interconnect provided anti-jamming capability. The structure consists of an RDRA made from a high DK ceramic material, which is excited by coaxial feeding. The proposed model has been fabricated and tested using a Vector Network Analyzer (VNA). The anti-jamming service features in the L1 band at 1.5742 GHz. Furthermore, a (SRR) cell integrated with a Z-shaped strip line is used to convert right-hand circular polarization (RHCP) to left-hand circular polarization (LHCP) as a novel feature. The gain enhancement is another novel feature, which is obtained due to polarization conversion. This study also emphasizes the significance of metrology in ensuring accurate measurement of key antenna parameters, including \(S_{11}\) S 11 , gain, axial ratio and impedance. The ceramic DRA also contributes to the measurement and detection of environmental signals.
