摘要

This article presents a stacked dipole antenna operating at industrial, scientific, and medical-band (902-928 MHz) for ingestible temperature monitoring applications. To date, the proposed capsule system has a smaller dimension of 11 mm (diameter) x 16 mm (length) compared to other existing capsule systems. To achieve size reduction of the capsule system, the conjugating matching method is utilized and the matching circuits are intended to be removed. The whole capsule system is simulated in a one-layer muscle phantom for initial parameters optimization, and the impedance bandwidth ranges from 908 to 924 MHz, which is sufficient for data transmission requirements and also brings robustness on the performance stability whatever the surrounding organs is. A wireless data transfer link is established between the integrated capsule and external receiver. An in-vivo measurement is also conducted to validate the system practicability, and besides, the temperature date of a rat is monitored in real time and shown at a display screen.
