Abstract :
A 42 × 44-element reflectarray using interdigital gap loading structure element is used as a passive reflector for elimination blindness propagation channel. The proposed reflectarray is designed with a 58-degree scattering angle and fabricated to experimentally investigate the performance and effectiveness in improvement of the receiving signal noise ratio (SNR) and channel quality. It was found that the received power level were improved by more than 12 dB for cumulative distribution function (CDF) at 1% as compared to those without the reflectarray in the none-line-of-sight (NLOS) environment.
