“…Many reflectarray antennas have been designed to realize the desired performances in recent years. Among all these designs, single-layer implementation, commonly using element structure of particular shape, is much easier to design and fabricate than multiple-layer implementation and will not degrade the bandwidth performance at the same time [3][4][5][6].…”

A dual-polarized broadband single-layer reflectarray antenna based on square spiral element is presented in this paper. Two designs with similar square spiral structures but different construction processes and transition patterns are investigated and compared. The comparison results show that the design varying the length of the first stub of one-arm square spiral is more suitable for building the reflectarray. Several 441-element reflectarray antennas fed by horn with different offset angles are also simulated and compared to show the broadband characteristic. A reflectarray with offset angle of 15 degrees is then fabricated and tested. The measured results show good radiation performances, and the 1-dB gain bandwidth of 34.7% is obtained. The measured gain is 27.1 dB at the center frequency of 15 GHz, which is equivalent to 45.6% aperture efficiency.

In this work, the design and realization of a circular reflectarray antenna (CERA) with semi‐ elliptic rings are carried out for X‐band. In order to achieve a fast design optimization process, 3D EM simulated data‐driven multilayer perceptron neural network (MLP NN) model of the unit element is generated providing the unit reflection phase as a continuous function of the radii and gap of the ring for the width w = 0.5 mm on the FR4 with ∊r = 4.4, h = 1.5 mm. The proposed CERA consists of 148 unit cells taken symmetrical both in the Y and X‐axis. Thus, a meta‐heuristic optimization algorithm honey bee mating optimization (HBMO) is applied to 21 elements between 10 and 12 GHz to determine their optimal geometries for the required reflection angles according to the phasing scheme. The simulated and measured performances of the designed CERA have been found in good agreement and its performance is compared also with its counterpart designs in literature and resulted to exhibit superior performance.
