Abstract
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.
