چکیده
A dual-polarized paralle-plate waveguide slot array antenna operating at 24.5 GHz band is proposed in this paper. The architecture consists of two orthogonally oriented 20×19 radiating arrays, where the slots are positioned collinearly. centered longitudinal feeding introduced into waveguides, which offer improved aperture efficiency and higher cross-polarization discrimination (XPD) compared to conventional tilted approach. achieves a remarkable simulated radiation over 95% within operation bandwidth. prototype fabricated verified through measurements. measured results demonstrate an impedance bandwidth 13%, with reflection below -10 dB. Moreover, peak 54% 40%. XPD exceeds 26

متن کاملPost-Wall Waveguide Circuit Consisting of -junctions for a Center-Feed Parallel Plate Slot Array
The center-feed structure is applied to the post-wall waveguide fed parallel plate slot array to widen the frequency bandwidth. The center-feed antenna has a blocking area at its center. This blocking makes the sidelobe level high in the Eplane, therefore the width of the blocking area should be reduced. The authors propose a novel center-feed waveguide consisting of -junctions for this reducti...

A large bandwidth wide-slot antenna, fed by coplanar waveguide (CPW), is proposed. Experimental investigations and detailed simulations are conducted to understand its behavior and to optimize for broadband operation. The impedance bandwidth, determined by 10-dB return loss of the proposed slot antenna using both measurement and simulation, is about 131% (2.8 to 14GHz). In addition to be small ...
متن کاملDesign of Partially Parallel-Fed Hollow Waveguide Nallow-Wall Slot Array Antenna in Millimeter-Wave Band
High-gain and low-profile antennas are required for high-speed wireless communication systems and mechanically-scanning automotive radars in the millimeter-wave band. Waveguide antenna is one of the most attractive planar antennas for such millimeter-wave systems because of its low loss and high efficiency characteristics in high frequency band. Travelling-wave excitation is more effective for ...
