A Stacked triangular dielectric resonator antenna (DRA) fed by a conformal patch is proposed for WLAN applications. In this paper, triangular shaped three resonators with same dielectric constant and different sizes are stacked to improve the gain, bandwidth and radiation performances of DRA. An increase in bandwidth is further achieved by using air gaps. This Stacked DRA is excited by a conformal...
A novel dielectric resonator antenna design is presented for wideband applications in this letter. By using a dielectric resonator with an optimized H-shaped across section and an optimized trapezoidal patch adhered on the concave surface of the resonator as a feeding mechanism, an impedance bandwidth of about 62% (for VSWR les 2) , covering the frequency range of 3.6-6.85 GHz, is achieved. The measured...
