Characterization of Dumbbell Slots in Rectangular Waveguide by Method of Moments,
Abstract
Dumbbell slots are often used for an array to reduce their resonant length, and hence, their internal and external mutual coupling. The square dumbbell shunt slot is characterized by the moment method. As expected, the resonant length is shorter than a conventional rectangular slot. Also, changing the width of the dumbbell slot has the same effect as changing the length of the rectangular slot. However, for a small offset such that a part of the dumbbell is across the center line, changing the width of the dumbbell slot has little influence to its admittance.
