ANTENNA DESIGN I n this paper a non-resonant slotted waveguide antenna design method is present-ed. The internal and external mutual coupling between adjacent radiat-ing slots is considered in the described meth-od. In order to confirm the usefulness of this method, a non-resonant waveguide array antenna with longitudinal slots cut in a broad Design of a new waveguide slotted antenna array - e-fermat.org In this paper, a new waveguide slotted antenna array, in which T-shaped cross section waveguide is used as the radiating waveguide, is proposed and simulated. The T shaped radiating waveguide can reduce the waveguide profile height. The radiating slots are etched and inclined alternately on the top [1, 2, 3]. Design of Slotted Waveguide Array Antenna Fed by H-Plane ... number of slots in linear and or planar arrays, phase excitation, positions and size one can control the critical antenna parameters like main radiation beam, side lobe level, front to back ratio, bandwidth and choose an optimal design depending on the desired requirement. Design of a slotted waveguide array antenna involves a number of details ... Design of Substrate Integrated Waveguide Multi-band Slots ...
This work systematically presents a high-efficiency corporate-fed slot array antenna based on groove gap waveguide in the millimeter waves. A cavity-backed slot sub-array is firstly designed in a groove gap waveguide cavity. The cavity is fed through a coupling hole from groove gap waveguide distribution network at the bottom layer.

In this paper, a new waveguide slotted antenna array, in which T-shaped cross section waveguide is used as the radiating waveguide, is proposed and simulated. The T shaped radiating waveguide can reduce the waveguide profile height. The radiating slots are etched and inclined alternately on the top [1, 2, 3].
Slotted waveguide antennas are mostly employed in Radar applications. This paper analysis the structure and design procedures of slotted antenna in the broad wall. This design specifications are chosen for high gain and mechanical robustness. The slotted waveguide antenna designed is a directional type antenna with gain of 16db.
