Fundamental-Mode Leaky-Wave Antenna (LWA) Using Slotline and Split-Ring-Resonator (SRR)-Based Metamaterials

IEEE Antennas and Wireless Propagation Letters, 2013
A new composite right/left-handed (CRLH) slotline leaky-wave antenna (LWA) is proposed. The antenna, implemented by loading a slotline with split-ring resonators (SRRs), is designed to exhibit a balanced dispersion relation, with a continuous transition between the left-handed and the right-handed bands at 2.5 GHz.

Design of circularly polarized planar leaky‐wave antenna using characteristic mode analysis

IET Microwaves, Antennas & Propagation, 2021
In the present study, a characteristic mode analysis (CMA) is proposed for the first time to design a periodic leaky‐wave antenna (LWA). By applying CMA to the unit cell of a periodic travelling wave structure, the open stopband is suppressed and ...
