Efficiency-Driven Design for Planar Antennas With Lossy Materials

This article demonstrates a design strategy for improving the radiation efficiency of a planar antenna made of a layered conductor of MXene with modest conductivity on a lossy PDMS substrate.New methods to reduce the conductor loss and the dielectric loss are proposed.On the one hand, the conductor loss is minimized by identifying the location of h
