چکیده

In order to realize a single-layer corporate-fed slot array, a hollow rectangular coaxial line is adopted as a feeding line. A 2×2-element subarray on a hollow rectangular coaxial line for the corporate-fed array is designed for the 60-GHz band. For the wideband operation, a cavity-backed wide slot is adopted as a radiating element. The 5.7% bandwidth for the reflection less than −20 dB is obtained in the subarray by simulation. The performance of a 16×16-element array is evaluated using the result of the designed subarray.

Excitation of a Longitudinal Slot on a Hollow Rectangular Coaxial Line by Metal Support of the Inner Conductor

This paper presents the excitation of a longitudinal slot on a hollow rectangular coaxial line by a metal support between two conductors and the fabrication by diffusion bonding of laminated metal thin plates. The measured loss of a straight line is 0.046dB/cm at 60GHz while the simulated one is 0.043dB/cm.

Design 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...

Circularly Polarized Circular Slot Antenna Array Using Sequentially Rotated Feed Network

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...

Design, simulation and Fabrication of Circularly Polarized Fabry-Perot Antenna for Ku Band

This paper deals with the design and simulation of a RHCP Fabry-Perot antenna for 14.5 GHz. Based on transmission line model, partially Reflecting Surface (PRS) was designed so thatgain enhancement and circular polarization simultaneously obtained. PRS consist of a square loop and meander-line at the top and bottom respectively. In order to achieve the resonance condition in orthogonal componen...
