“…(1) guarantees that different phase behaviors of the element at any location of the reflective surface will be accounted for in the design process. To show the adverse behavior of frequency factor on the reflective phase of the elements at various points of the aperture, the desired phase slope versus the frequency is calculated according to the following equation [15]:…”

Two main factors limiting the reflectarray bandwidth are different phase slopes versus the frequency at every point on the aperture and the phase limitation of comprising elements at different frequencies. Considering these two factors, a novel design method is proposed to implement a dual-band, dual-polarized reflectarray antenna in X and Ku bands. An optimization algorithm is adopted to find the optimum phase for each unit cell on the reflectarray aperture. The best geometrical parameters of the phasing elements are suggested based on the phase variation of the element versus frequency and the element position with respect to the antenna feed. Many different classes of phasing elements with identical base structures are investigated to provide a lookup table for the optimization algorithm. The optimum phases are obtained so that two collimated beams are realized within the frequencies of 10.95 GHz to 11.7 GHz and 14 GHz to 14.5 GHz with vertical and horizontal polarizations, respectively. From the experimental results, the peak directivity of 27.1 dBi and 30.6 dBi, aperture efficiency of 42% and 67%, and cross-polarization level of less than –15 dB and –20 dB were obtained in the lower and upper bands, respectively.

“…Merging two independent functionalities in one structure reduces the antenna space occupation without sacrificing the antenna performance. Many efforts have been made in recent years to realize dual band and/or dual-orthogonal polarization reflectarrays with acceptable performance [9,[12][13][14][15][16].…”

In this letter, a single-layer broadband wide band-ratio (ratio of f higher to f lower ) reflectarray that can achieve different linear polarizations at the X-band and the K-band is designed. Its elements consist of a split square loop with two square shaped phase delay lines (outer structure) and a phoenix square loop (inner structure) operating at the X-band and the K-band, respectively. The ingeniousness of the design is that the outer structure and the inner structure can achieve a 0 • − 360 • phase shift by adjusting the phase shift lines and the side length of the inner square ring, respectively. At the same time, they do not affect each other in space. Different polarizations corresponding to the two structures are orthogonal to each other, so their electrical performances do not affect each other. To verify our design concept, the reflectarray is fabricated and measured in a microwave anechoic chamber. The simulated and measured results are in good agreement. The measured gains are 23.6 dBi at 10 GHz (f lower ) with aperture efficiency of 48%, and 30.6 dBi at 22 GHz(f higher ) with aperture efficiency of 43%. The 1-dB gain bandwidths are 20% (9.1 GHz-11.1 GHz) at the X-band and 19% (19.8 GHz-23.9 GHz) at the K-band. The band-ratio of the reflectarray is 2.2. A single-layer dual-band wide band-ratio reflectarray with dual-linear polarization is confirmed.

“…The Phoenix cell concept was firstly introduced in [2] and many other Phoenix cells were derived later [3][4][5][6][7][8]. As their name suggests, Phoenix cells are characterized by rebirth capabilities, which means that their geometry comes back to its initial state after a complete 360° phase cycle.…”
