Today, along with the advances in circuit printing technology it has become possible to fabricate band lines integrated with circuit elements. The band lines are known as microstrip lines and the whole packages are called microstrip antennas. The microstrip antennas have three layers, including conductive patch layer, dielectric sub layer, and ground conductive layer. One of the most important ...
This paper presents a flexible multiple-input, multiple-output (MIMO) antenna with ultrawideband (UWB) performance for smart clothing applications. The MIMO is comprised of four octagonal-shaped radiators several slots loaded into them, and it offers frequency range 2.9–12 GHz. unit cell has size 0.26λ0 × 0.164λ0 0.014λ0 the 0.48λ0 0.014λ0, where λ0 corresponds to lowest operating frequency. ra...
in this paper a new low profile substrate integrated waveguide (siw) probe-fed h-plane horn antenna structure with improved gain is proposed. the proposed antenna consists of two waveguides including a rectangular and a taper one, in which both, first and third modes of the structure are simultaneously excited leading to a uniform field distribution along the radiating aperture of the antenna a...
The recent advancements in technology in the wireless technology has led to rise of wearable antennas made of different fabrics. It is an unconventional antenna, meant to be a part of clothing and body. The radiating element is made of copper or any other conductor while the substrate used for wearable antenna application are textile or cloth based material. This literature review tends to reve...
Introduction. Due to the good electrical and thermal properties of carbon, carbon-based materials represent a major trend is various applications, including electromagnetic compatibility. Among materials, graphite-impregnated woven fabrics new in field shielding, with perspective being used for protective clothing. The novelty proposed work consists exhaustive comparative analysis sample shield...
Communication technology is increasingly pervading everyday life. The rapid progress in wireless communication besides the increasing interest in wearable antennas and electronics in civil, medical, sport wear and military domains promises to replace wiredcommunication networks in the near future in which antennas are in more important role. Recently, there has been growing interest in the ante...
Presently, it is difficult to measure the characteristic impedance of embroidered microstrip line for its conductive anisotropy directly. The published work had proposed use S-parameters estimate port a balanced dipole antenna, and cannot be used calculate lines with one arm. Thus, still problem on measuring obtaining 50 Ω line. Therefore, taking reflection coefficient as an intermediate variab...
