A method of manufacturing an integrated radio frequency (RF) module, comprising structurally forming at least one RF waveguide and at least one RF radiator of a metalized ceramic material. The RF waveguide(s) and the RF radiator(s) are connected and operatively coupled with each other. Each of the RF radiator(s) comprises a metalized outer wall and at least one metalized axial ridge extending along an inner surface of the outer wall. The method further comprises sintering the metalized ceramic material to create a monolithic structure comprising the RF waveguide and RF radiator, and operatively coupling RF circuitry to the RF waveguide(s).

Near-Field Microwave Heating System and Method

A microwave heating device includes a variable frequency microwave power supply, a waveguide launcher, and a fixture to contain a material to be heated, with the fixture located directly adjacent to the end of the launcher. All heating occurs in the near-field region. This condition may be insured by keeping the thickness of the fixture or workpiece under one wavelength (at all microwave frequencies being used). The launcher is preferably a horn or waveguide configured to apply the microwave power to a small area to perform spot curing or repair operations involving adhesives and composites. The spot curing may secure components in place for further handling, after which a thermal or oven treatment will cure the remaining adhesive to develop adequate strength for service. A related method is also disclosed.

DUAL-POLARIZED ANTENNA, RADIO FREQUENCY FRONT-END APPARATUS, AND COMMUNICATIONS DEVICE

This application discloses a dual-polarized antenna, a radio frequency front-end apparatus, and a communications device.
