This paper introduces the development of two Printed Inverted F Antennas (PIFA) to be integrated in a patch worn on the back of human body. This study is part of SACHA project (Search And Computerize Human Acts) whose main aim is to design a tracking device for monitoring the elderly suffering from Alzheimer disease. The first antenna frequency is 868 MHz and will be used to communicate with a specific SIGFOX communication technology. A second frequency (1575.42 MHz) is used for GPS geolocation. The proposed development is a part of research in Human Health Monitoring field, based on the monitoring of the behavior, the location and the position of the patient, and could deeply help the medical team or family to instantly respond through a warning generation.
