Bidirectional high data rate satellite links are needed in emergency conditions where other telecommunication infrastructures are not available. This paper focuses the design of Co-radiator transmit receive antenna suitable for satellite Ku-band emergency communications. The reported antenna consists of two elements in the same patch which is operated from 10.7 GHz to 12.5 GHz for reception and 14...
The design of a rectangular WR62 waveguide fed finline (tapered slot) antenna is presented. The antenna utilizes a tapered E-plane ridge within the rectangular waveguide to provide a smooth matched transition. This type of antenna is targeted for high power phased array applications where dielectric materials are prohibitive. Simulation shows wideband characteristics from covering the full WR62 bandwidth...
A new broadband dual polarized L-shaped horn antenna and associated waveguide feed structure is presented. The antenna is well suited for millimeter-wave polarimetric phased array systems requiring wide-angle scanning and ease of integration with planar circuits. A stereolithographic fabrication process is employed to obtain the complex angles and intricate features that are essential for the antenna...
