Circularly polarised dielectric resonator antenna

open access: yesElectronics Letters, 1994
A circularly polarised dielectric resonator antenna is reported. The circular polarisation is obtained by exciting the two orthogonal HE/sub 11 delta / modes of a cylindrical ring dielectric resonator in phase-quadrature. Measured results show that the antenna has an axial ratio of less than 3 dB over a beam width of 100 degrees with a minimum value of

90° dielectric polariser in circular waveguide

open access: yesElectronics Letters, 2000
Experimental results for a 90° dielectric polariser in a circular waveguide are presented. A small slot notched into the circular waveguide wall, used for the accurate alignment of the dielectric plate, has led to a decrease in the relative phase shift by 15.7%. A new U-shape impedance matching structure results in a bandwidth of 12.4%.
