Theory of Seamless-Scanning Periodic Leaky-Wave Antennas based on -Symmetry with Time to Space Mapping
Amar Al-Bassam, Simon Otto, Dirk Heberling +1
Periodic Leaky-Wave Antennas (P-LWA) offer highly directive and space-scanning radiation. Unfortunately, they have been plagued by the ``broadside issue'', characterized by a degra…
