Exponentially tapered slot antenna and assembly

An antenna assembly comprising:

• a first exponentially tapered slot antenna (ETSA) including an exponentially tapered edge on a radiating element positioned between a substrate and a superstrate collectively defining a first antenna panel including a first end and a second end;
• a second ETSA including an exponentially tapered edge of a radiating element positioned between a substrate and a superstrate collectively defining a second antenna panel including a first end and a second end;
• a first corner formed by an orthogonal alignment of the first end of the first antenna panel with the second end of the second antenna panel;
• a first capacitive loaded panel adjacent the first corner in operative electrical communication with the first ETSA and the second ETSA;
• a third ETSA including an exponentially tapered edge on a radiating element positioned between a substrate and a superstrate collectively defining a third antenna panel including a first end and the second end;
• the third antenna panel offset parallel to the first antenna panel;
• a second corner formed by an orthogonal alignment of the first end of the second antenna panel with the second end of the third antenna panel;
• and
• a second capacitive loaded panel adjacent the second corner in operative electrical communication with the second ETSA and the third ETSA.
