Theory of Seamless-Scanning Periodic Leaky-Wave Antennas based on $\mathcal{P}\mathcal{T}$-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…
