All-Dielectric Ceramic 3-D Printed Unidirectional Leaky-Wave Antenna at mm-Wave Frequencies
Guillaume François, Masoud Sakaki, Henrik Jansen +3
An all-dielectric leaky-wave antenna, radiating unidirectionally at broadside without the use of a metallic ground plane, is designed and manufactured. It operates in the 70-90 GHz…
A 28-GHz Varactor-Based RIS With Continuous Phase Control: From Unit-Cell Modeling to Programmable Wavefront Control and Synthesis
Spandan Manna, Florian Reher, Karim El Isa +2
This paper presents a 28 GHz varactor-based reconfigurable intelligent surface (RIS) platform with continuous phase control and establishes a unified device-to-system validation fr…
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…
Exceptional Point Perspective of Periodic Leaky-Wave Antennas
Amar Al-Bassam, Dirk Heberling, Christophe Caloz
Over the past decade, the issue of gain degradation at broadside in periodic leaky-wave antennas (P-LWAs) has been resolved, using a circuit modeling approach, by introducing prope…
Broadside Dual-channel Orthogonal-Polarization Radiation using a Double-Asymmetric Periodic Leaky-Wave Antenna
Amar Al-Bassam, Simon Otto, Dirk Heberling +1
The paper demonstrates that double unit-cell asymmetry in periodic leaky-wave antennas (P-LWAs), i.e. asymmetry with respect to both the longitudinal and transversal axes of the st…
Circular Polarization of Periodic Leaky-Wave Antennas with Axial Asymmetry: Theoretical Proof and Experimental Demonstration
Simon Otto, Zhichao Chen, Amar Al-Bassam +3
The paper includes two contributions. First, it proves that the series and shunt radiation components, corresponding to longitudinal and transversal electric fields, respectively,…
