Document Type and Number:
Japanese Patent JPS63100804
Kind Code:
A
Abstract:
An antenna is formed with a hollow waveguide (1) having a narrow slot (2) in one face. A Vivaldi horn type radiator (5) is mounted with a coupling arrangement (3, 4) to couple energy in the waveguide through the slot to the radiator. The slot can be a non-radiating longitudinal slot, parallel to the waveguide axis, and several radiators may be mounted in a non-resonant slot along the length of the waveguide to form a linear resonant array.
