Abstract
This paper introduces an innovative low-profile dipole array (TCDA), featuring a wide bandwidth. The individual antenna elements are designed for direct feeding from a standard 50 O coaxial cable, circumventing the need for costly baluns. Additionally, to mitigate common mode resonance, a metallic wall is integrated into the array, simulating the boundary conditions of conventional dipole arrays. The design culminates in an infinite array boasting an impressive bandwidth ratio of 6.1: 1 (0.68-4.17GHz) with VSWR < 4. Moreover, the antenna demonstrates robust performance across a 60° scan angle from 0.61 to 3.96GHz (6.5:1) in the E-plane, maintaining a VSWR below 4. Concurrently, in the H -plane, the proposed antenna achieves a scanning span of 60° from 0.7 to 2.95GHz (4.2:1) with active VSWR < 4. Remarkably, its profile remains exceptionally low at merely 0.08?low. The proposed design is distinguished by its low-profile architecture, extensive bandwidth, and wide scanning capabilities.
