All‐dielectric circularly polarised loop antenna made of high‐permittivity ceramic/water

IET Microwaves, Antennas & Propagation
A kind of all‐dielectric circularly polarised (CP) loop antenna made of high‐permittivity material is proposed. The leaky‐wave radiation from a high‐permittivity dielectric waveguide is utilised here to support the operation of the proposed antenna.
