本文提出了一种利用径向介电常数变化的宽带同心半分裂圆柱介质谐振器天线的设计和研制方法。已分别讨论了均质、双层和三层同心半裂CDR。天线参数，如层的安排，几何参数，和探针长度的影响进行了研究。为了验证结果，使用市售的微波层压板制造了两层和三层同心半裂式陶瓷。在每种情况下，输入反射系数，辐射方向图和天线增益进行了模拟和测量。模拟结果与实测结果吻合较好。© 2014 Wiley Periodicals，Inc. Int J RF and Microwave CAE 25：321-329，2015.
Design and development of wideband concentric half‐split cylindrical dielectric resonator antenna (CDRA) using permittivity variation in radial direction has been proposed in this article. The homogeneous, two‐layer and three‐layer concentric half‐split CDRAs have been discussed separately. The effect of antenna parameters such as layer arrangement, geometrical parameters, and probe length are investigated. To validate the results, two‐layer and three‐layer concentric half‐split CDRA have been fabricated using commercially available microwave laminates. In each case, the input reflection coefficient, radiation pattern, and antenna gain are simulated and measured. Good agreements between simulated and measured results have been obtained. © 2014 Wiley Periodicals, Inc. Int J RF and Microwave CAE 25:321–329, 2015.
