摘要：An antenna comprising a waveguide component and a probe assembly, coupledto the antenna assembly, for distributing radio frequency (RF) energy to slots positionedon at least one of the broad walls of the waveguide component. The probe assembly canbe positioned at the approximate center point of the waveguide component to present adesired impedance to the waveguide cavity and to distribute RF energy of substantiallyequal amplitude and phase to each section of the waveguide cavity. The probe assemblyincludes 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 thepost, and (2) a post slot having an opening located along the post and traversing thepost cavity. A probe pin, which is inserted within one end of the post cavity and connectedto the opposite end of the post cavity, couples the RF energy to the waveguide cavity viathe post slot.
