Abstract :
The authors present the design of a linearly polarized RLSA (radial line slot antenna). A key feature consists of the slot arrangement that realizes the linear polarization of the rotationally symmetric travelling wave excitation. The design is verified by experiments. Fresnel patterns indicate the reasonable XPD of more than 17 dB. To suppress the reflection from slots, beam tilting techniques should be used in the practical design of the linearly polarized RLSA.<>
