Dielectric-based leaky-wave antenna for high gain using a printed surface-wave source [PDF]
A multilayer leaky-wave antenna (LWA) is presented for microwave and millimetre-wave frequencies. By placing two superstrate dielectric layers on top of a base grounded dielectric slab, a practical resonant cavity structure can be realised for high gain ...

A Miniaturized Reconfigurable CRLH Leaky-Wave Antenna Using Complementary Split-Ring Resonators
Composite Right-/Left-Handed (CRLH) Leaky-Wave Antennas (LWAs) are a class of radiating elements characterized by an electronically steerable radiation pattern. The design is comprised of a cascade of CRLH unit cells populated with varactor diodes.

Full‐Space Scanning Leaky‐Wave Antenna Utilising Spoof Surface Plasmon Polaritons
In this paper, we present a novel spoof surface plasmon polariton leaky‐wave antenna (SSPP‐LWA) capable of full‐space beam scanning. The proposed antenna achieves full‐space beam scanning from ‐90° to +90° across the frequency band of 9.8–13.3 GHz, with a high scanning rate of 5.94° per 1% frequency variation.
