DESIGN AND ANALYSIS OF DUAL-BAND SWASTIKA SHAPED MICRO-STRIP PATCH ANTENNA

Abstract

In this paper, a novel single-layer circular swastika shaped antenna with dual-band characteristics is presented. The proposed patch antenna, with design operating frequencies of5.5 GHz and 10.3 GHz, is targeted for applications in C-band and X-band. More importantly, the circular swastika-shaped micro strip patch antenna exhibits a theta polarized radiation pattern with gains of 11.17 dB and 9.05 dB with corresponding reflection Coefficients of (VSWR = 1.419) and (VSWR =1.046) at 5.5 GHz and 10.3 GHz, respectively. The Measurements of the fabricated patch antenna corroborate the simulation results obtained in HFSS. This dual-resonance antenna, with comparatively high gain performance, can be easily integrated into systems for satellite and radar communications.
