In this letter, a frequency-scanning planar antenna composed of a phase gradient metasurface and feed structure is proposed. The phase gradient metasurface can couple the wave from the feed into a spatial radiated wave whose propagation direction is manipulated by frequency as long as the feed provides a similar electromagnetic field to that of spoof surface plasmon polariton rather than exciting...
In this paper, the channel measurements for 5th generation mobile networks (5G) potential spectrum at 3.35 GHz, 4.9 GHz and 5.4 GHz have been performed in the urban macro cell scenarios in China. The measured cases include line-of-sight (LOS) and non-line-of-sight (NLOS) propagation. After acquiring the channel impulse response from the measurement data, the empirical log-distance path loss models...
In this paper, we present a novel microstrip patch antenna specifically designed using planar metamaterial patterned substrate. It is developed based on an ordinary patch antenna, and isolated triangle gaps and crossed strip-line gaps are etched on the metal patch and ground plane respectively. This patterned substrate was demonstrated in literature to have left-handed characteristics. In this way,...
