Compact, Low-profile and Robust Inversely E-shaped antenna Integrated with EBG Structures for Wearable Application

Abstract

A compact and robust inversely E-shaped antenna (IESA) integrated with electromagnetic band-gap (EBG) is presented for wearable applications at 2.4 GHz. The EBG introduced in this paper to shield the antenna from body effects, due to its high natural dielectric. With EBG, the antenna shows good performance under bending and loading human body. The design has overall dimension of $46 \times 46 \times 2.4$ mm3. The integration of antenna with EBG shows an improvement of a gain of 7.8 dBi and bandwidth of 27%. It also reduces the specific absorption rate (SAR) by more than 95.
