Abstract:
This paper presents an extremely small antenna, together with its model, for wireless biomedical devices. Most of the implantable devices require very small dimensions. On way to achieve it is to use microtechnologies to obtain the required size reduction. One of the most challenging devices to integrate is the antenna, required if we want to communicate with the device trough a wireless link. The proposed antenna uses a MEMS structure to convert the incoming electromagnetic field into a voltage. This antenna allows the reception of signals using a carrier in the kHz range and uses only a chip area of 2x2 mm2.
