Wearable PIFA antenna for smart glasses application
2016 IEEE International Conference on Computational Electromagnetics (ICCEM), 2016This paper presents a wearable antenna of 2.4 GHz Bluetooth for smart glasses application. This antenna consists of two elements array planar inverted-F antennas (PIFA) using coaxial cable to connect two antenna elements together. Moreover, Specific Absorption Rate (SAR) in user's head is also calculated using the model provided by CST software.

11th International Symposium on Antenna Technology and Applied Electromagnetics [ANTEM 2005], 2005
In this article, a frequency reconfigurable antenna using the ON/OFF states of a MEMS (micro‐electro‐mechanical system) switch is presented. This structure is based on a planar inverted‐F antenna (PIFA), designed with an L‐shaped open slot etched upon its main plate.

User's Impact on PIFA Antennas in Mobile Phones
VTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009Thanks to a recent grip study, CAD models of the human hand have been generated, investigating user's impact on PIFA antennas in mobile phones. The simulation results show that the hand and especially the index finger exhibit a major contribution in determining the total loss when compared to the upper torso alone, while the influence of the position ...

Multiband PIFA Vehicle Telematics Antennas
IEEE Transactions on Vehicular Technology, 2005Compact, low-cost antennas for multiband telematics applications on vehicles are described. The multifrequency band antennas are variations on the printed inverted-F antenna (PIFA) principle. One type of PIFA is a compact variation of a conventional antenna while the other is a novel planar version customized for different mounting positions such as ...
