Abstract :
A circularly polarised cylindrical dielectric resonator antenna fed by a single microstrip feedline is investigated. By printing two microstrip lines on the surface of the cylindrical dielectric resonator together with a vertical feeding strip, two orthogonal modes in phase quadrature are excited to obtain a circular polarisation. The impedance bandwidth, axial ratio bandwidth, antenna gain and radiation pattern are presented
