A Low Profile Dual-Polarized Tightly Coupled Dipole Array of C-X-Band

The paper presents a model of a low-profile dual-polarized tightly coupled dipole array (TCDA) for operation in the 4-12 GHz band. In contradistinction to the well-known TCDAs, the proposed array is distinguished by its simplicity of design, the period of 12×12 mm, and the small height of 5.63 mm (including the thickness of the upper homogeneous matching layers of 1.67 mm and the substrate layers of 3.968 mm, without the use of balancing transformers). The selected array period allows taking into account the design requirements of the feed network for the array elements. The broadband of the TCDA (at VSWR <; 3.6) is achieved using the upper matching layers.
