Systems and methods for ultra-ultra-wide band AESA

A current sheet array wavelength scaled antenna aperture comprising:

• a high frequency sub-array including a plurality of first unit cells scaled to support a first operating frequency band having a respective maximum operating frequency f1, the first operating frequency band representing a full operating frequency band of the current sheet array wavelength scaled antenna aperture;
• one or more low frequency sub-arrays arranged adjacent to the high frequency sub-array, each low frequency sub-array including a respective plurality of second unit cells scaled to support a second operating frequency band having a respective maximum operating frequency f2 smaller than f1;
• and
• one or more capacitors each of which coupled to a respective first unit cell of the high frequency sub-array and a respective second unit cell of the one or more low frequency sub-arrays.

A method of providing an antenna array, the method comprising:

• providing a high frequency sub-array including a plurality of first unit cells scaled to support a first operating frequency band having a respective maximum operating frequency f1, the first operating frequency band representing a full operating frequency band of the antenna array;
• arranging a plurality of low frequency sub-arrays adjacent to the high frequency sub-array, each low frequency sub-array including a respective plurality of second unit cells scaled to support a second operating frequency band having a respective maximum operating frequency f2 smaller than f1;
• and
• coupling each of one or more first capacitors to a respective first unit cell of the high frequency sub-array and a respective second unit cell of the low frequency sub-arrays.
