Abstract :
A Slot antenna design based on recently developed gap waveguide technology has been presented in this work. This antenna can be built easily by having the feed network on the bottom metal plate, where the ridge will be distributing the waves for equal excitation of each slot element, and the top metal plate will have the slots. Design and simulation results of the basic T-junction for a corporate-feed network and the single element slot show that - it is possible to have an array antenna with BW of 15 % or more based on ridge gap waveguide technology.
