Abstract
Recently there have been much interest in the GPS antenna performance improvement. In this paper, we propose very small patch antenna for GPS band. The proposed antenna resonance frequency was adjusted using the ground plane and variable capacitor connected the frame. The fabricated antenna was used a FR4 substrate by considering the difficulty and economical efficiency. Antenna measurement results was obtained good characteristics of VSWR 1.2, the passive antenna gain -0.60 dBi, the active antenna gain of 29 dB in center frequency of 1575.42 MHz GPS band.
