Flexible and wearable antennas

Abstract

in this chapter discusses the planar-inverted F-antenna (PIFA) is used for the wearable application, which reduces the effect of radiation on the human body by reducing the radiated power towards the body. As the Global System for Mobile Communication (GSM) transmitted power is reduced, the battery life is increased. This performance is achieved due to matching the feed with the load that reduces the power loss because of reduction in the reflected power. A FlexPIFA antenna is designed from the flexible dielectric material for the smart clothing application. The transmission range was calculated based on Friis expression. Another PIFA antenna that is integrated with the human body for a mobile phone.
