Electrically Small MEMS Antenna for Wireless Biomedical Microsystems

This paper presents an extremely small antenna for wireless biomedical devices. Most of the implantable devices require very small dimensions, requiring the use of microtechnologies to obtain the necessary size reduction. One of the most challenging devices to integrate is the antenna, required if we want to communicate with the device through a wireless link. The proposed antenna uses a MEMS structure to convert the incoming electromagnetic field to a voltage. This antenna allows the reception of signals using a carrier in the kHz range and uses only a chip area of 1.5 times1.5 mm2.
