Abstract

This paper investigates dual right-angled triangular-shaped dielectric resonator antenna (DRA) excited with asymmetric slot coupled. Here, the asymmetric slot coupled ground plane is responsible for generating orthogonal modes to realize circular polarization (CP) in the proposed antenna. The designed antenna shows TE11δ mode and is confirmed by the rotation of the electric field inside the triangular DRA. This proposed antenna is realized by using dual right-angled triangular dielectric resonators (DRs), which are separated by an optimal gap to be responsible for the generation of wideband CP bandwidth. Proposed antenna shows -10 dB input impedance bandwidth of 20.22% (3.25-3.98 GHz) and 3-dB axial ratio bandwidth in broadside direction of 16.11% (3.31-3.89 GHz). In addition, this antenna offers an average gain and radiation efficiency of 5.64 dBi and 89.00% in the broadside direction respectively. The designed antenna shows right-hand circular polarization and is suitable for Wi-MAX applications (3.3-3.7 GHz).

非对称槽耦合激励双三角形DRA在宽带圆极化中的应用

研究了非对称槽耦合激励下的双直角三角形介质谐振器天线。其中，非对称槽耦合地平面负责产生正交模式，以实现天线的圆极化。设计的天线显示TE11δ模式，并通过三角DRA内部电场的旋转来证实。该天线采用双直角三角形介质谐振器(dr)实现，它们之间由最佳间隙分隔，负责产生宽带CP带宽。该天线-10 dB输入阻抗带宽为20.22% (3.25-3.98 GHz)，宽带方向3 dB轴比带宽为16.11% (3.31-3.89 GHz)。此外，该天线在宽方向上的平均增益和辐射效率分别为5.64 dBi和89.00%。设计的天线呈现右圆极化，适用于Wi-MAX应用(3.3-3.7 GHz)。
