“…Good bandwidth performance is obtained, and the 1-dB gain bandwidth of 38% is achieved. In [14], different from the former two mentioned papers, the Archimedes spirals are not attached to patch or ring structures. Only four Archimedes spirals are adopted to form the phasing element.…”

“…Differing from the formula-based Archimedes spiral described in [14], the square spiral is hard to express by simple equations related to its length. Therefore, the study of the reflection performances varying with one particular parameter is hardly carried out.…”

“…Combining a square spiral and the configuration of four-arm Archimedes spirals [14], a novel reflectarray using a four-arm square spiral with a small aperture is first introduced in [16]. In this paper, the design details of the square spiral structure, especially the comparison of two different constructions, are provided.…”

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.

To cite this version:Hassan Salti, Raphaël Gillard. A single layer stub-patch phoenix cell for large band reflectarrays. Abstract-A novel Phoenix cell for large band reflectarray antennas is presented here. The cell starts with a simple square patch whose phase shift is controlled by its sides' length. The size of the patch is then fixed and open-stubs with variable length are connected to it. To complete the phase range at the central frequency, the stub-loaded patch then shrinks gradually until it disappears completely allowing the cell to rebirth. The cell is characterized by a phase range of 360˚ at the central frequency, linear phase responses with respect to frequency and a reduced phase dispersion of less than 34˚/GHz within a 40% bandwidth. The suggested cell retains the same bandwidth when accounting for incidence angles of up to 30˚ and a reduced bandwidth of 32% accounting for higher incidence angles of up to 45˚.Index Terms-reflectarray, large band, Phoenix.

“…A number of outstanding reflectarray designs are developed to achieve these good merits in recent years. Most of the phase-shift elements used in the reflectarray antennas are patches [2], rings [3], stubs [4], slots [5] and their combinations [6][7][8]. A certain shifting phase can be generated by adjusting the dimension of key part or rotating the whole element by a certain angle.…”

Abstract-A single-layer reflectarray antenna using circular patch with four semicircular ring slots is proposed in this paper. By changing the diameter of the circular patch, the proposed phasing element can realize phase range about 500 degrees with relatively stable reflection magnitude. Besides, the reflection phase curve with smooth slope is almost linear. Based on the good phase response, a 421-element reflectarray is designed, simulated and fabricated. The measured results show that 1.5-dB gain bandwidth can attain 24% at the center frequency of 15 GHz.
