Abstract :
The admittance and resonant length of an isolated longitudinal waveguide slot radiating in a finite ground plane are calculated. The problem is solved by applying a spectrum of two-dimensional solutions, referred to as the S2DS method. The reflection coefficient of a single slot in a WR-187 terminated waveguide was measured as a function of slot length and slot offset at 4.8 GHz. This makes it possible to determine the resonant length and resonant conductance for the slot. The resonant length is predicted within 0.5%.<>
