摘要

研究了发射阵列天线的近场聚焦特性。总结了设计过程，提出了一种ku波段聚焦发射阵列天线，其中元件是带线延迟互连的孔径耦合贴片。将发射阵列的聚焦性能与经典远场设计进行了比较。结果表明，近场聚焦反射射线是高微波功率应用的理想选择。

Near-field characteristics of focused transmitarray antennas

Near-field focusing characteristics of transmitarray antennas are investigated. The design procedure is summarized and a Ku-band focused transmitarray antenna is presented where the elements are aperture-coupled patches interconnected with stripline delays. The focusing performance of the transmitarray is compared with classic far-field designs. It is shown that a near-field focused reflectarray can be a good candidate for applications requiring high microwave power.
