提出了一种用于超宽带（UWB，3.1- 10.6GHz）的新型结构简单、紧凑的微带介质谐振器天线。该设计结合了小尺寸微带天线和薄平面微带天线的优点。该设计提供了高辐射效率、一致的全向特性以及整个频带内的低交叉极化。天线尺寸为15 × 33 mm 2，厚度为5.08 mm。介质谐振器（DR）的形状，以容纳激励饲料和介电基板被切割，以容纳DR。共面波导被用来给天线。
A new simple compact monopole type dielectric resonator antenna (DRA) for ultrawideband (UWB, 3.1-10.6 GHz) applications is presented. The design combines the advantages of small size DRA and thin planar monopole antennas. The design provides high-radiation efficiency, consistent omnidirectional characteristics, and low cross polarization within the entire band. The antenna size is 15 × 33 mm2 with 5.08 mm thickness. The dielectric resonator (DR) is shaped to house the excitation feed and the dielectric substrate is cut to house the DR. The coplanar waveguide is used to feed the antenna.
