Abstract

In one aspect, the inventive concepts disclosed herein are directed to an antenna array system employing a current sheet array (CSA) wavelength scaled aperture. The CSA wavelength scaled aperture can include a first frequency region associated with a first operating frequency band and a second frequency region associated with a second operating frequency band. The first operating frequency band can include one or more current sheet sub-arrays having a respective plurality of first unit cells scaled to support the first operating frequency band. The second operating frequency band can include one or more current sheet sub-arrays having a respective plurality of second unit cells scaled to support the second operating frequency band. The CSA wavelength scaled aperture can include one or more capacitors each of which coupled to a respective first unit cell of the first frequency region and a respective second unit cell of the second frequency region.

Description

Background technique [0001] Active electronically scanned array (AESA) systems provide reliable performance over corresponding ultra-widebands (UWBs) of operating frequencies. AESA systems are commonly used in communication systems, military and weather radar systems, electronic intelligence systems, or biological or medical microwave imaging systems. AESA systems utilize arrays of operable radiating elements (or antenna elements) via corresponding sets of transmit / receive modules (TRMs). By steering each of its antenna elements independently, an AESA system provides relatively high reception / transmission performance through the constructive accumulation of signals associated with multiple antenna elements. Additionally, a single failure of one or a few antenna elements within an AESA system has little effect on the operation of the AESA system as a whole due to the inherent ability to simultaneously use and independently steer corresponding multiple antenna elements. Also, ...
