A New Technique for Broadband Matching of Open-Ended Rectangular Waveguide Radiator [PDF]
Sensors, 2023 The maximum reflection at an open end of a standard rectangular waveguide is about −10 dB in its operating frequency range. It is often used without matching. For critical applications, it is desirable to further reduce the reflection coefficient.

The Design of a Sliding Rectangular Waveguide Array Antenna for Beam Steering [PDF]
Journal of Electromagnetic Engineering and Science, 2023 In this paper, we designed a sliding waveguide array antenna that can be beam-steered via mechanical manipulation. This reduces the vulnerability of electronic beam-steering radars mounted on ships or aircraft to electromagnetic pulse (EMP) attacks.
