Abstract :
In this article, a new hybrid dielectric resonator antenna (DRA) has been investigated to produce circular polarization over a wide frequency band. The targeted application is to produce a compact antenna for satellite navigation systems. The obtained design was fabricated and measured, showing impedance matching from 1.09 to 1.83 GHz, i.e. over 50% bandwidth. The radiation characteristics of the antennas were also characterized. From 1.13 to 1.63 GHz, the achieved gain is over 1.5 dBic and the axial ratio is under 1 dB at boresight. The half-power beamwidth is greater than 75°, and the axial ratio beamwidth (AR ≤ 3 dB) is over 90°.
