Liquid metasurface-based periodically stacked radome design

We present liquid metasurface-based periodically stacked radome design. Radome is a layer placed above the antenna to protect it from weather disturbances. The layer protects the antenna but reduces its gain. Periodic stacking of liquid metasurface based radome improve the antenna parameters like gain and bandwidth. Microstrip patch antenna is used as basic antenna to check the improvement in gain. The comparison of microstrip patch antenna, patch antenna with simple multilayer radome, patch antenna with liquid metasurface multilayer radome and patch antenna with liquid metasurface periodically stacked multilayer radome is presented in the manuscript. The improvement in terms of gain is clearly visible from the comparison of results for all the designs. Efficiency is also increasing by adding liquid metasurface periodically stacked multilayer radome to patch antenna.
