Metasurface Based Pattern Reconfigurable Antenna For 2.45 Ghz Ism Band Applications

In this article, a Z-shaped antenna is designed for 2.45 GHz ISM band applications. The proposed antenna is surrounded by metasurface-based unit cells. The unit cells are designed to reflect for the proposed frequency. Each of this unit cells are activated with the help of a diode. Unit cell is considered active by switching on the diode of respective unit cell. According to the activation of unit cell the pattern of the antenna will be reconfigured. The 2.45 GHz ISM band pattern reconfigurable microstrip antenna is presented. The radiation pattern of the antenna can be steered toward a desired direction by activating appropriate metasurface unit cell, minimizing the interference and optimizing medium usage. The proposed antenna performance is presented with the help of reflection coefficient and the pattern steerable capability by activating metasurface unit cells. The proposed antenna is having azimuth-pattern reconfigurable capability around 360 degrees.
