In this paper, we present a new type of coupler which applicable to low leakage two-dimensional communication (2DC) sheets. Our 2DC system can transfer signals and powers simultaneously by using microwaves. Our goal is to realize supplying 1 W/cm power through the sheet safely and extracting the power with the coupler that is smaller than 100mm. For safety, the microwave leakage from the sheet should be reduced so that the localized specific absorption rate (SAR) value conforms to the safety guideline. First of all, the 2DC sheet that satisfies above criteria is designed. Next, the proposed type and previous type of coupler are designed and their performances are measured. As a measurement result, proposed coupler can absorb 54 % of power that flows in the sheet at the peak frequency, 3.58 GHz. It is nearly 5 times greater than that of previous type of coupler at the same frequency.
