    In this paper, a novel single-layer Gemini-shaped patch antenna with dual-band characteristics is presented. The proposed patch antenna, with design operating frequencies of 6.53 GHz and 8.62 GHz, is targeted for applications in C-band and X-band. More importantly, the Gemini-shaped microstrip patch antenna exhibits a theta polarized radiation pattern with gains of 6.036 dBi and 9.556 dBi with corresponding reflection coefficients of -18.69 dB (VSWR = 1.263) and -24.31 dB (VSWR = 1.129) at 6.53 GHz and 8.62 GHz, respectively. The measurements of the fabricated patch antenna corroborate the simulation results obtained in Sonnet Suites version 16.52. This dual-resonance antenna, with comparatively high gain performance, can be easily integrated into systems for satellite and radar communications. © 2017 ACES.
