Abstract Smartdielectric resonator antenna (DRA) having beam control mechanism is anew area to be explored by antenna researchers. Proposed new geometry DRA has low loss, design flexibility, high efficiency, compact size and desired radiated beam control. Developing beam control in new geometry DRAs is investigated for the first time in this letter. Unique technique for beam control and beam width control is proposed using pit top and mount top DRA. Gain is controlled from 5.0 to 9.98 dBi and beam is controlled from ±30° to ±70° in broadside radiation pattern. U shape pit DRA has maximum directive gain of 9.98 dBi and efficiency 98% at 5.8 GHz frequency. Measured and simulated results of radiation pattern and reflection coefficient are found to be in close proximity. Hardware of U shape pit top DRA, mount top DRA, left side arc top DRA, right side arc shape top DRA is developed and investigated. Mobile and cellular communication network need wide coverage, hence large beam width is required. Narrowing of beam width at higher order mode is also achieved.

用于光束宽度和方向控制的智能 DRA

摘要 具有波束控制机制的智能介质谐振天线（DRA）是天线研究人员探索的一个新领域。提出的新几何 DRA 具有低损耗、设计灵活性、高效率、紧凑的尺寸和所需的辐射束控制。在这封信中首次研究了在新几何 DRA 中开发光束控制。使用坑顶和安装顶 DRA 提出了用于光束控制和光束宽度控制的独特技术。增益控制在 5.0 到 9.98 dBi 之间，波束控制在 ±30° 到 ±70° 的宽边辐射方向图中。U形坑DRA在5.8 GHz频率下具有9.98 dBi的最大定向增益和98%的效率。发现辐射方向图和反射系数的测量和模拟结果非常接近。U形坑顶DRA、安装顶DRA、左侧弧顶DRA、开发和研究右侧弧形顶部DRA。移动和蜂窝通信网络需要广泛的覆盖范围，因此需要大的波束宽度。还实现了高阶模式下波束宽度的变窄。
