A broadband slotted ridge waveguide antenna array - INFONA A longitudinally-slotted ridge waveguide antenna array with a compact transverse dimension is presented. To broaden the bandwidth of the array, it is separated into two subarrays fed by a novel compact convex waveguide divider. A 16-element uniform linear array at X-band was fabricated and measured to verify the validity of the design. Parallel-Plate Slot Array Antenna for Deployable SAR ... 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.
