摘要

为了实现频率和极化混合重配置，研究人员对 4 × 4 阵列进行了研究。天线阵列的辐射元件由圆柱形介质谐振器、威尔金森功率分压器、PIN 二极管和介质基板组成。PIN 二极管控制威尔金森功率分配器中每个分支的状态，以实现频率和极化的可重构性。为了验证设计的可行性，我们测量了所建议的天线阵列的制造样品。结果表明，天线阵列可以在工作频率和极化之间自由切换。它可在 1.93 至 4.6 千兆赫的带宽内进行频率重配置，并可在 2.96 至 3.39 千兆赫范围内连续调谐线性极化、左手圆极化和右手圆极化三种常见极化状态。

Reconfigurable dielectric resonator antenna and array with frequency and polarization flexibility

To implement frequency and polarization hybrid reconfiguration, a 4 × 4 array has been investigated. The radiation elements of the antenna array consist of cylindrical dielectric resonators, Wilkinson power divider, PIN diode, and dielectric substrate. The PIN diode controls the states of each branch in the Wilkinson power divider to achieve frequency and polarization reconfigurability. To verify the feasibility of the design, a fabricated sample of the proposed antenna array has been measured. The results demonstrate that the antenna array can be switched freely between its operating frequencies and polarizations. It operates within a bandwidth of 1.93 to 4.6 GHz for frequency reconfiguration, and three common polarization states—linear polarization, left-handed circular polarization, and right-handed circular polarization—can be continuously tuned from 2.96 to 3.39 GHz.
