Wireless telemetry based secure communication has been extensively worked to improve the life quality of patients having heart problems, diabetic problems and so on. Information of appropriate biosensors could be transferred via implant antennas to which, there are a growing research interests. In the scope of this work, we have designed a wide band antenna for biotelemetry communication. Radiation diagram, reflection coefficient, gain and such critical parameters of designed antenna are investigated. CST Studio Suite 2008 software was employed during the design. The working frequency range, the properties of the implant medium and the position of the device were all considered via this software. On the other hand the antenna was encapsulated to a proper cavity so that the extra radiation would not be produced. Acquired results of this simulation work constitute a concrete infrastructure for clinical applications. ©2010 IEEE.
