abstract

  • In this research article, a single-fed dual-band circular polarized (CP) dielectric resonator
    antenna (DRA) for dual-function communication, such as GPS and WLAN, was made. Initially, the
    proposed design process was initiated by designing a linearly polarized singly fed-DRA. To attain
    CP fields, the cross-shape conformal metal strip was optimized to excite the fundamental and the
    high-order mode in the two frequency bands. The metallic strip (parasitic) was utilized on top of
    the rectangular DRA to improve and widen the impedance and axial ratio (AR) bandwidth. This
    step led to a 2.73% improvement on the lower band and an impact of 6.5% on the upper band while
    on the other side a significant improvement was witnessed in the AR bandwidth in both frequency
    bands. A prototype was designed and fabricated in order to validate its operations. The measurement
    outcomes of the proposed antennas authenticated wideband impedance bandwidths of 6.4% and
    25.26%, and 3-dB axial ratios (AR) of 21.26% and 27.82% respectively. The prototype is a decent
    candidate for a global positioning system (GPS) and wireless local area network (WLAN).
