Slotted waveguide antenna (SWA) arrays offer clear advantages in terms of their design, weight, volume, power handling, directivity, and efficiency. For broad-wall SWAs, the slot displacements from the wall centerline determine the antenna's sidelobe level (SLL). This paper presents an inventive procedure for the design of broadwall SWAs with desired SLLs. For a specified number of identical longitudinal...
A new approach in designing a multi-band microstrip patch antenna is illustrated. The presented approach is based on combining a rectangular and a triangle patch with proper slots placed on each part. First, rectangular slots, following a Chebyshev distribution, are inserted into the rectangular patch and next, a triangular slot is inserted into the triangular patch. The new structure is fed by a...
