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 ...
