“…These unwanted modes would otherwise be supported between the side grounds and the substrate ground. This type of transmission line is known as finitewidth ground-backed coplanar waveguide (FW-GBCPW) [3]. The T/R array makes use of a combination of FW-GBCPW and micro-stripe transmission lines (MSL).…”

Abstract-An active-antenna array with 18 transmit elements and 18 receive elements is designed and fabricated. This T/R array can work at two different frequencies (19.5 GHz and 21.5 GHz) with multiple levels of isolation between the transmit and receive channels. A hybrid element-level vector finite element and adaptive multilevel fast multipole method (ELVFEM/AMLFMA) is applied to simulation the performance parameters of the array element and the full array fast. To obtained the maximum directivity of the array, the best distances of the T/R elements in the array are optimized by using the genetic algorithm (GE) combining with VFEM/AMLFMA. The design efficiency of the array is improved at a ratio of 30%. Finally the performance of the T/R array fabricated is measured in experiments and some good results are obtained.

“…Among these advantages, CBCPWs allow easy implementation of mixed coplanar/microstrip circuits, reduce radiation effects, and raise effective permittivity. These and several other advantages make CBCPWs ideally suit for MIC as well as monolithic MIC (MMIC) applications [1][2][3][4][5][6][7][8][9][10][11][12].…”

“…Various types of CBCPW structures have been presented and analyzed in the literature [4][5][6][7][8][9][10][11]. The CBCPWs were analyzed by using the spectral domain approach (SDA) [4], conformal mapping method (CMM) [5,6], and quasi-static SDA [7].…”

“…The CBCPWs were analyzed by using the spectral domain approach (SDA) [4], conformal mapping method (CMM) [5,6], and quasi-static SDA [7]. The dispersion characteristics of CBCPWs have been obtained by using the rigorous mode matching method [8], alternative formulation of the transverse resonance technique [9], full-wave SDA and Galerkin's method [10], and a hybrid two-dimensional finite-difference time-domain/Marquardt curve-fitting technique [11].…”

Abstract-In this paper, accurate synthesis formulas obtained by using a differential evolution (DE) algorithm for conductor-backed coplanar waveguides (CBCPWs) are presented. The synthesis formulas are useful to microwave engineers for accurately calculating the physical dimensions of CBCPWs. The results of the synthesis formulas are compared with the theoretical and experimental results available in the literature. A full-wave electromagnetic simulator IE3D and experimental results are obtained in this work. The average percentage error of the synthesis formulas obtained by using DE algorithm is computed as 0.67% for 1086 CBCPW samples having different electrical parameters and physical dimensions, as compared with the results of quasi-static analysis.
