Main intension is to calculate admittance and radiation pattern of longitudinal shunt slot in rectangular waveguide using Method of Moments MoM technique. Resonant length calculation of the slot is a critical parameter in the design of waveguide slot array antenna. All computed results are compared with simulated results. The performance of planar arrays comprising longitudinal shunt slot radiators in the broad wall of conventional rectangular waveguides has a number of limitations: The scan range in the plane perpendicular to the waveguide axis E-plane is restricted because of the relatively large width of the waveguide which translates into a wide inter-element spacing in this plane.

Design of Rectangular Waveguide Slot Array Antenna.

INTRODUCTION Rectangular Slotted Waveguide Antennas SWAs [1] radiate energy through slots cut in a broad or narrow wall of a rectangular waveguide. This means the radiating elements are an integral part of the feed system, which is the waveguide itself, leading to a simple design not requiring baluns or matching networks. A waveguide array based on rectangular waveguide with high gain and low side-lobe is designed in this paper. Inclined slot cut in the narrow wall of rectangular waveguides is employed for horizontal polarization HP radiation. The realized gain of single rectangular waveguide slot antenna reaches 21.1dBi and the side-lobe is below -34.7dB at the center frequency of 9.4 GHz.. In this letter, we propose a high gain rectangular waveguide board wall slot array antenna, which is integrated with one dimensional subwavelength periodic corrugated grooves and artificially soft surface structure. The corresponding far field radiation characteristics are investigated. The simulation results show that the gain of planar 2 8 slot array antenna with the introduction of.

Slot antennas in waveguides provide an economical way of the design of antenna arrays. The position, shape and orientation of the slots will determine how or if they radiate. Figure 3 shows a rectangular waveguide with a drawn with red lines snapshot of the schematic current distribution in the waveguide walls. In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes. The array consists of four, rectangular, slot elements, arranged side-by-side in a linear array and developed around 5GHz. Two feed points, at opposing sides of the printed array, each excite two of the slot.
