Abstract :
A frequency-independent, triplate feed structure is described that is easily matched, even if slot shape and dimensions are varied, and has the advantage of causing a minimum of disturbance to the aperture fields. This feed structure does not extend the impulse response of the antenna. The properties of the slots can thus be separated from the effects of the edges of the ground plane by making measurements in the time domain. The results show that the resonant frequency may be predicted by simple cavity theory.<>
