dc.description.abstract	This letter presents an ultra-wideband (UWB) dual-linearly-polarized tightly coupled dipole array (TCDA) designed for wide-angle scanning in both E and H planes. The proposed TCDA design achieves exceptional performance, boasting a bandwidth of 10.2:1 (1.3–13.3 GHz) and an active voltage standing wave ratio (VSWR) of less than 3 when scanning up to ±70° in both E and H planes. This superior performance is achieved through the incorporation of four new design elements: gradual shorting posts, resistance patches, a notched balun, and a composite double-layer superstrate. These design elements effectively suppress various resonances, improve impedance matching, and enhance beam scanning capabilities. The antenna element has dimensions of 0.43λc × 0.43λc × 0.57λc, where λc represents the free space wavelength at the center frequency of 7.3 GHz. A 12×12 element array was fabricated and tested, further validating the proposed TCDA's noteworthy features, including dual-polarization operation, ultra-wide bandwidth, and the widest scanning angle in both E- and H-planes.

Abstract:

This letter presents an ultra-wideband (UWB) dual-linearly-polarized tightly coupled dipole array (TCDA) designed for wide-angle scanning in both E and H planes. The proposed TCDA design achieves exceptional performance, boasting a bandwidth of 10.2:1 (1.3–13.3 GHz) and an active voltage standing wave ratio (VSWR) of less than 3 when scanning up to ±70° in both E and H planes. This superior performance is achieved through the incorporation of four new design elements: gradual shorting posts, resistance patches, a notched balun, and a composite double-layer superstrate. These design elements effectively suppress various resonances, improve impedance matching, and enhance beam scanning capabilities. The antenna element has dimensions of 0.43λc × 0.43λc × 0.57λc, where λc represents the free space wavelength at the center frequency of 7.3 GHz. A 12×12 element array was fabricated and tested, further validating the proposed TCDA's noteworthy features, including dual-polarization operation, ultra-wide bandwidth, and the widest scanning angle in both E- and H-planes.
