“…In summary, the dipole's optimization variables in the ECM are After that, the ECM for analyzing the radiator structure with this kind of dipole has to be developed for efficient optimization design. The conventional ECM [8], [9] does not work out, because it is difficult to find the mapping relationship between the physical dimensions of the proposed dual-diamond dipoles and the lumped element values in circuit model.

“…However, it is time consuming and tedious to extract the equivalent inductance of dipoles when the physical dimensions of the dipoles changes. Thereafter, another improved ECM is proposed in [9] to model the radiator structure with interdigital capacitive couplings [9] and parallel plate capacitive couplings [7]. Furthermore, a mapping relationship between lumped element values and physical dimensions is also developed to speed up the optimization design [9], [7].…”

This paper proposes an efficient and systematic design approach for tightly coupled dipole array (TCDA) designs. In this approach, the radiator structure and feeding structure are designed and optimized based on their equivalent circuit models (ECM) respectively. A novel ECM is proposed to accurately describe the impedance characteristics of the radiator structure with dual-diamond dipoles. The proposed ECM of the radiator structure keeps its accuracy for variable design parameters. The ECM of the proposed feeding structure is also developed to analyze its impedance characteristics. As compared with conventional brute-force optimizations based on full-wave simulations, the two ECMs make it easy and efficient to design wideband TCDAs. A dual-polarized TCDA is designed with the proposed approach to illustrate the efficiency of the approach. The resultant TCDA operates in a wide frequency band of 0.87-10.14 GHz with VSWR≤2 for broadside radiation. Meanwhile, the VSWR value under all conditions (broadside, ±60 • scanning in E-and H-planes) remains ≤3 over the frequency band of 0.8-9 GHz. A 10 × 10 prototype is fabricated to demonstrate the design. INDEX TERMS Tightly coupled dipole array (TCDA), equivalent circuit model (ECM), phased array. I. INTRODUCTION
