Low-profile Slot Antenna integrated with a thin polymer non-metallic battery

In this study, a low-profile slot antenna was designed with the purpose of having the ability to be integrated into the structure of a layered non-metallic polymer battery. Using a set of previous published parameters for the slot antenna, the structure was modified in the CST Microwave Studio package in order to suit the needs of a battery substrate. A second slotted ground plane was attached beneath the antenna. The composite substrate and ground planes replicates the layered structure of a plastic planar battery, with the intention of reducing the size of the slots on the bottom plane which also acts as a battery terminal. The effect of the slot size and tan δ value of the substrate on the radiation patterns was also investigated.
