Metamaterial-Based Transmit Arrays for Multibeam Antenna Array Assemblies

摘要

Transmit arrays or radio frequency lenses can provide large time delay variations. The transmitter array comprises a plurality of time-delay unit (TDU) cells each having a capacitive patch and a rectangular wire loop separated by a dielectric material. Rectangular wire loops allow current continuity between adjacent TDU cells even if TDUs of different sizes are included in the transmitter array.
