Web22 okt. 2024 · The designed reflectarrays exhibits a wider gain bandwidth compared with other reflectarray structures proposed in literature. The 3-dB gain bandwidth of the fabricated antenna in the X and Ku bands is 39 % and 44 %, respectively. The gain of the proposed antenna is 21.8 and 26.6 dB at 7.8 and 12.2 GHz, respectively. Web31 jan. 2015 · It is demonstrated that the fabricated TTD reflectarray operates over a bandwidth of 40% without any significant chromatic aberrations. The proposed antenna provides a realized gain of 23 dB when fed with an X-band horn antenna and shows a gain variation of about 4 dB in the 8–12 GHz range.

Ultra-Wideband Reflectarray Regarding the ultra-wideband (UWB) designs, up to date, there are few reported works. In [17], reflective spatial time-delay units were developed to improve the bandwidth of the reflectarray. The spatial time-delay unit is a unit cell of a ground-plane-backed frequency selective surface (FSS)
