- Abstract
- This paper proposes a circular dual-loop GPS antenna with an extended cavity structure for a small GPS array. The antenna element consists of lower and upper circular loops printed on a high-dielectric ceramic substrate, and the extended cavity structure exists above the ground plane to improve the isolation characteristic. Antenna characteristics depending on cavity height are analyzed and the results show that the proposed structure can improve the isolation characteristic by reducing the leakage field. The isolation is further enhanced by miniaturizing the antenna size with maximized the effective dielectric constant. © 2018 KIEES.
