摘要：
本文报道了一种利用特征模理论（CMT）和二进制遗传算法（BGA）的多模介质谐振器天线（DRA）形状合成方法。通过将天线的特征模响应（谐振频率和品质因数）纳入代价函数，形状合成过程在不包含激励馈电的情况下进行。通过优化过程，由四面体单元形成一个非规范介质体，以支持所需的模态特性。作为所提设计方法的演示，从矩形和圆柱形体积中分别合成了两个工作在2.45 GHz的三模MIMO DRA。合成的MIMO DRA复杂形状（基于矩形）随后采用纳米颗粒喷射氧化锆进行制造。采用探针与缝隙馈电的组合来激励所需模式。由于特征模的正交性和馈电网络的精心设计，所有端口之间实现了大于20 dB的隔离度。
英文摘要：
In this paper, we report a shape synthesis method for multi-mode dielectric resonator antennas (DRA) using characteristic mode theory (CMT) and a binary genetic algorithm (BGA). By including the antenna's characteristic modal responses (resonance frequencies and quality factors) in the cost function, the shape synthesis process is conducted without including excitation feeds. Through the optimization procedure, a non-canonical dielectric body is formed from tetrahedral elements to support the required modal properties. As a demonstration of the proposed design approach, two three-mode MIMO DRAs are synthesized from both a rectangular and a cylindrical volume to operate at 2.45 GHz. The synthesized MIMO DRA's complex shape (based on rectangle) is then fabricated using Nanoparticle jetted zirconia. A combination of probe and slot feeds are employed to excite the desired modes. Due to the orthogonality of the characteristic modes and the careful design of the feeding network, isolation $>20$ dB is achieved between all ports.
