Broadband RF radial waveguide feed with integrated glass transition

摘要

An antenna and a method of using the antenna are disclosed. In one embodiment, the antenna includes a radial waveguide, an aperture that operates to radiate a radio frequency (RF) signal in response to an RF feed wave supplied by the radial waveguide, and RF energy in the waveguide. And a radio frequency (RF) choke that operates to prevent leakage through a gap between the outer portion of the aperture and the outer portion of the aperture surface. [Selection] Figure 2
