ABSTRACT:
An antenna comprising a waveguide component and a probe assembly, coupled to the antenna assembly, for distributing radio frequency (RF) energy to slots positioned on at least one of the broad walls of the waveguide component. The probe assembly can be positioned at the approximate center point of the waveguide component to present a desired impedance to the waveguide cavity and to distribute RF energy of substantially equal amplitude and phase to each section of the waveguide cavity. The probe assembly includes a post, connected to one or both of the rear and front walls, and a probe pin. The post, which is typically positioned within the center of the waveguide cavity, comprises (1) a post cavity located within and extending along at least a portion of the post, and (2) a post slot having an opening located along the post and traversing the post cavity. A probe pin, which is inserted within one end of the post cavity and connected to the opposite end of the post cavity, couples the RF energy to the waveguide cavity via the post slot.
