Bosma, S. (author), van Rooijen, N. (author), Alonso Del Pino, M. (author), Llombart, Nuria (author)We present a resonant leaky-wave lens antenna, fed by a circular waveguide with annular corrugations in the ground plane. The proposed leaky-wave feed reduces the impact of the spurious TM0 leaky-wave mode in all planes over a wide bandwidth while reducing assembly complexity compared to previous methods. The proposed leaky-wave antenna has...journal article 2022
