Abstract
Enhanced components and assemblies for microwave radio frequency (RF) antenna feed systems are provided. One example includes radiating probes that propagate RF signals to intermediate waveguides that feed polarizers or filters associated with horn antenna elements. The radiating probes can couple to corresponding transmit/receive circuitry using coaxial link elements. The radiating probes comprise tunable components which can be shaped/sized to produce desired output characteristics (e.g., frequency ranges and gain properties). Many radiating probes can be integrated into a cover plate assembly that feeds an array of horn antennas. Interface elements with integrated waveguides can provide RF sealing between radiating probes and provide radiative coupling from radiating probes to corresponding waveguides that feed the array of horn antennas.
