A 12×16-Element Double-Layer Corporate-Feed Waveguide Slot Array Antenna
نویسندگان
چکیده
The plate-laminated waveguide slot array antenna is a high-efficiency and wide-band antenna in the millimeterwave band. However, in the conventional corporate-feed circuit, the number of radiating elements is limited to be a power of two by using a cascade of T-junctions. In this paper, we propose the corporate-feed with a cross junction and an asymmetric Tjunction for 12×16 elements. The bandwidth for VSWR less than 1.5 is 7.64%. Antenna efficiency of 82.6% is obtained at the design frequency of 61.5 GHz by simulation. Index Terms — waveguide slot array, corporate-feed, cross junction.

An E-Band Partially-Corporate Feed Slot Array with Laminated Quasi Double-Layer Waveguide Structure and PMC Terminations
Authors have developed various types of single-layer slotted waveguide arrays with simple structure and high mass-productivity. Those arrays have been successfully applied to relatively narrowband commercial services for satellite broadcast reception in 12 GHz band and wireless IP access at home in 26 GHz band etc. However, one weak point of that antenna is that the bandwidth of the antenna gai...
متن کاملDesign of a 45-degree Linearly-polarized Hollow-waveguide Slot Two-dimensional Array Antenna with a Full-corporate-feed Circuit in the Lower Layer
Hollow-waveguide slot array antennas [1] have been widely used in the milli-meter band since they do have neither radiation loss nor dielectric loss. Furthermore, they have been developed especially for military application such as radars. For commercial application such as fixed wires access system, mass production at low cost has been required and single layer hollow-waveguide slot array ante...

This paper presents the design, simulation, and measurement of two low-cost broadband circularly polarized (CP) printed antennas: a single element and an array at C band. The proposed single element antenna is excited by an L-shaped strip with a tapered end, located along the circular-slot diagonal line in the back plane. From the array experimental results, the 3 dB axial ratio bandwidth can r...
