摘要

A wideband microstrip reflectarray antenna (RA) is proposed using a novel unit-cell for X-band applications. The unit-cell is composed of a logarithmic toothed microstrip element and two-variable phase-delay lines (PDLs) for the required phase compensation in the RA. By adjusting the lengths of the PDLs, a smooth and almost linear phase variations of 627 is achieved at the frequency of 10 GHz. Based on the proposed element, a 144-element center-fed RA with dimensions of 216 mm × 216 mm is designed at 10 GHz and simulated using CST software. Then, a fabricated prototype RA is tested to validate the design approach. The maximum measured gain is 25.3 dB at 10.4 GHz, whereas the gain is 24.6 dB with 44.2% aperture efficiency at the design frequency of 10 GHz. Also, the measured gain frequency characteristic shows the 1 and 3-dB gain bandwidths of 24.8% and 42.3%, respectively, and the measured radiation patterns verify the simulated ones as well.
