Circularly Polarized Aperture Coupled Zeroth Order Resonance Antenna for mm-Wave Applications
Keywords:
Aperture–coupled antenna, Substrate Integrated Waveguide (SIW), Zeroth-Order Resonance (ZOR)Abstract
In this work, a millimetre-wave aperture–coupled antenna was offered by mode synthesis. In order to increase half power beam width (HPBW), the present study united a TM010 mode, which was generated by aperture slot of substrate integrated waveguide (SIW), and a zeroth-order resonance (ZOR) mode of a metamaterial polarizer mushroom. The results were confirmed by an equivalent circuit and a full wave simulator. Moreover, to prevent mm-wave fed loss, the study made use of a SIW feed with a slot which reduced the interference between a feed and a mushroom metamaterial structure as a polarizer antenna. The proposed antenna was fabricated and measured at 35 GHz. The simulated results roughly agreed with the measured results.
