Abstract

In this work, a novel excitation technique for non-inclined edge wall waveguide slots is developed. The proposed method greatly facilitates the manufacturing of large edge wall slotted waveguide arrays with very low cross polarization levels at the cost of deviation from shunt slot model. Slots are characterized using the infinite array approach in two dimensions and using this characterization data, travelling wave type linear arrays are designed. A planar array is also formed using previously designed linear ones. Designed antenna arrays are simulated and the results show that the infinite array approach is suitable for the design of these types of antennas. © 2010 IEEE.
