Metamaterial-based transmit array for multi-beam antenna array assembly

摘要

A transmit array, or radio frequency lens, can provide a large change in time delay. The transmit array comprises several time delay unit (TDU) cells each having a capacitive patch and a rectangular wire loop separated by a dielectric material. The rectangular wire loop allows current continuity to be maintained between adjacent TDU cells even when different sized TDUs are included in the transmit array.
