In this work, different configurations of electrically reconfigurable radial waveguides are presented: a configuration with pass/stop regions, a configuration with tunable narrowband filters and a configuration with integrated phase shifters. Potential applications for the different configurations are also proposed. First, the design and experimental results for a reconfigurable radial waveguide using PIN diodes and operating in the band 5.2-5.8 GHz (11%) are presented and discussed. Then, the principle of radial waveguide with tunable narrowband filters using varactors is described and an application for Frequency Modulated Continuous Wave (FMCW) radars is proposed. Finally, a new radial-line slot array antenna with electrically beam-steering ability is proposed.
