Abstract
Slot antennas have long been an integral part of wireless systems and have been known for their robust, flat construction. Since its inception, there have been many developments. However, as new design concepts continue to emerge, difficulties remain. The main theme of this thesis is related to these difficulties and introduces new ideas for matrices and aperture element. The single polarization limit is the first barrier, especially for waveguide aperture ranges, which can very often produce only a single linear polarization. In both communication systems, dual polarity is crucial This is because the four radar channels (HH, HV, VH and VV) provide MIMO / variation and characteristic information and applications for radar. Some studies have used two sets of waveguides to create double polarization, one for polarization and the other. The matrix becomes a large and inefficient structure. Achieving double polarization with a single waveguide is great. However, there are not many examples of this design now in the general literature. In addition, many emerging communication systems aim to integrate multiband bipolarized slot components into a single waveguide slot.
