摘要：

In this paper, a new dielectric resonator antenna (DRA) is introduced for wideband applications, where a simple L-shaped dielectric resonator (DR) is excited by a conformal inverted-trapezoidal patch connected to a microstrip line. It is observed that the impedance bandwidth can be expanded by using an inserted intermediate substrate, an L-shaped DR, and an inverted-trapezoidal patch feed mechanism. The experimental and numerical results were carried out and compared, showing a good agreement. The measured results demonstrate that the proposed DRA achieves an impedance bandwidth of about 71.4% for VSWR <= 2, covering the frequency range from 3.87 to 8.17 GHz. Furthermore, this antenna provides a stable broadside radiation pattern across the operating bandwidth.
