The Radial Line Slot Antenna Using Non-Resonant Cross-Slot Pair for Radiating Waveguide Termination

We have proposed the radial line slot antenna (RLSA) using non-resonant cross-slot pair for radiating waveguide termination. This radiating waveguide is advantageous in term of reflection suppression from end of radial line. The reflection characteristics of the calculation and the measurement results are less than -15dB around 38.0GHz. In this time, we show the first fabricated RLSA using non-resonant cross-slot pair for radiating waveguide termination.
