- Abstract
- This article proposes a novel feeding mechanism to improve the isolation characteristics in the GPS L1 and L2 bands for electromagnetically small arrays (aperture diameter<). In the mechanism, a feeding patch is sandwiched between two radiating patches and excited by two pins with a 90 degrees phase difference. To improve the isolation, ceramic with a high dielectric constant is used as the antenna substrate, and then four identical antennas are mounted on the ground platform. The results prove that the proposed design approach can achieve high isolation in the arrays. (c) 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:359-362, 2014
