N2 - This paper presents a compact active circularly polarized antenna for Global Navigation Satellite System (GNSS) signal reception. The antenna is designed to operate at GPS LI (1,575 MHz) and GLONASS LI (1,602 MHz) bands, and its size is 64mm × 64mm × 7.42mm, suitable for mounting on a commercial drone. Within this limited size, hybrid-based orthogonal feed and two-staged low noise amplifier (LNA) circuits are packed all together on a high permittivity (ϵr = 10) multi-layer substrate. Passive antenna performances exhibit a reflection coefficient of less than-15 dB, an antenna gain of 2.84 dBic, an axial ratio (AR) of less than 3dB and corresponding axial ratio beamwidth of more than 123° in the operation band. The fabricated active antenna including the LNA circuit shows the gain more than 28.5 dBic and noise figure less than 1.4 dB at the target bands.
