چکیده
An antenna mounted underneath the top cover of a wearable device, fed by an ultralow-profile connector, is proposed for Bluetooth-low-energy (BLE) communication at 2.4 GHz. As to be used it essential that should compact in size and tolerant against nearby medium change. The modified planar inverted-F (PIFA) we propose consists main patch parasitic element broaden bandwidth. end shorted miniaturize $25\times10.8$ mm, fitting well inside watch-type device. Also, complete ground layer makes radiate outward direction, minimally interact with back-side medium. This results reflection coefficient being insensitive change on backside. has peak gain 3.62 dBi along 20% efficiency impedance bandwidth 80 MHz (2.4–2.48 GHz). To examine communicative operation practice, received signal strength indicator (RSSI) prototype device measured various postures orientations, demonstrating reliable connectivity within typical indoor distance 10 m. Lastly, embedded electromyography’s wireless monitoring.

Modified E-shaped Pifa Antenna for Wearable Systems
A new wearable antenna for applications in communication systems used in military and police work has been developed. The proposed modified E-shaped PIFA antenna covers the nominal band of 380–400 MHz, and the functionality is guaranteed independently of the user’s clothing and the presence of lossy materials, such as wet clothing, mud or snow. The design is based on numerical simulations and m...
متن کاملCompact MIMO Antenna with Cross Polarized Configuration
MIMO is the key technology to improve spectrum efficiency in the wireless communications. However, MIMO may perform poorly as a mobile terminal with a very small antenna. This paper describes an experimental study on the performance of a compact MIMO antenna. In order to improve the performance, a cross polarized configuration was investigated as well as a co-polarized configuration. Experiment...

متن کاملA compact stacked Quasi-fractal microstrip antenna for RFID applications
In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...
