Summary:
In the past decade, methods to improve antenna performance by using metamaterial superstrate can be approximately differentiated into three categories according to the height. The first is half-wavelength height that can raise the single patch antenna directivity significantly by the research of [1]-[2]. The second is quarter-wavelength height with an artificial ground plane which can provide 90 degree phase reflection and bring almost the same performance as the first one by using the research of [3]-[5]. The last one is the lowest height profile (below 0.1 wavelength) which can also provides approximate 90% aperture efficiency according to the study of [6]. Recently, an ordinary air-layered patch antenna widely applied in consumer fixed access point or similar products and enhanced by metamaterial super-strate structure is successful constructed and simulated. According to the measured result, the proposed metamaterial antenna radome can improve the antenna gain to about 2.0 dB.
