Abstract
An antenna having a line feed delivering a radiofrequency (RF) signal to or from a radial waveguide is provided. The radial waveguide may include radiating elements on its periphery for converting the RF signal into a wireless signal. Filter elements are disposed within the waveguide, interposed radially between the line feed and the waveguide periphery. The filter elements are controllable for tunably filtering of the RF signal in their vicinity. Portions of the RF signal propagating through the waveguide in different direction may be bandpass filtered differently or blocked, thereby allowing for both beamsteering and bandpass filtering to support multiple frequency bands concurrently. Also provided is a design for the filter elements as tunable filter components of a frequency selective surface.
