Planar Slot-Patch Antenna [PDF]
31st European Microwave Conference, 2001, 2001 This paper discusses investigations of leaky wave radiation from the slotline made on a low permittivity substrate. New findings on the field distribution of the space leaky wave propagating on a slotline with a wide slot are presented. The design of the antenna and its measured parameters are introduced, along with practical experience acquired ...

Rectangular Slot Array Antenna
Applied Computational Electromagnetics Society, 2020 Slot antenna elements are quite popular for use in flat-panel arrays, due to their compactness and relatively large bandwidth. According to Babinet’s Principle, slots and dipoles are duals in performance. Therefore, a vertically placed slot is horizontally polarized and a horizontally placed slot is vertically polarized.
