Abstract

Two integrated antenna designs are presented to work in Medical Body Area Network Band. The upper antenna is rectangular microstrip patch antenna in both designs. The lower layer for first design is novel truncated metastructure with circular geometry. The lower layer for second design is truncated 2 × 2 array of circular elements. The final integrated antenna in both designs has very compact dimensions of 0.42λ0 × 0.42λ0 × 0.013λ0 The primary purpose of designing the antenna is to achieve low specific absorption rate (SAR) while maintaining its compactness and robustness. Significant reduction in SAR is achieved making the antennas good candidates for wearable devices.
