Boresight Gain Enhanced with Cylindrical Metasurface Lens
In this paper, a transmission-type electromagnetic metasurface lens which can be conformal to a cylindrical surface is designed and employed to enhance the boresight gain of a feeding antenna. The objective gradient of the transmission phase is formulated and implemented with four-layer slot unit cells. Focused electric field strength and power density are observed for a TM-polarized plane electromagnetic wave illumination at the designed focal point. Using a traditional probe-fed microstrip antenna as feeding, the cylindrical lens antenna can enhance its boresight gain by 11.4 dB for TM-polarized radiation at 10 GHz.
