Compact BLE Antenna With a Modified PIFA Configuration for Wearable EMG Monitor

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...

Compact multiband Planar Inverted F Antenna (PIFA)

Compact 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...

A Compact Wearable Slot Antenna for LTE and WLAN Applications

In this paper, a compact wide-band, ultra-thin and flexible slot antenna intended for wearable applications is presented. The presented antenna is designed to provide Wireless Local Area Network (WLAN) and Long Term Evolution (LTE) connectivity. The presented design exhibits a relatively wide bandwidth (16003500 MHz below -6 dB impedance bandwidth limit). The antenna is positioned on a 33 mm x ...

A 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...
