Full-Wave Analysis of a Waveguide Printed Slot Waveguide slot arrays have a number of advantages over other mi-crowave antenna systems. Among the others they have a very large efciency, due to the use of closed guiding structures for feeding, and a considerable mechanical strength. On the other hand, they have no exibility since, once an array is... Broadband array antenna Broadband array antenna.

Parallel-plate slot array antenna fed by rectangular waveguides at its lower-edge sides has been proposed. This antenna panel can be applied for dual circularly polarized deployable synthetic aperture radar (SAR) antenna onboard small satellite. As to confirm the feasibility of the antenna implementation, a development of one panel antenna system with single polarization (RHCP) has been conducted. Low Cross-Polarization Slab Waveguide Filter for Narrow A low cross-polarization slab waveguide filter for narrow-wall slotted waveguide array antenna with high gain horn is presented. In narrow-wall slotted waveguide array, the horizontal polarization (HP) is the co-polarization, while the vertical polarization (VP) is the cross-polarization.
