Line-start synchronous motors have attracted researchers’ interest as suitable replacements of asynchronous due to their high efficiency, which has been provoked by strict regulations regarding applicable efficiency classes in the EU market. The research becomes even more challenging it takes into consideration diverse rotor topologies with different magnet locations for this type motor. config...

To satisfy the demand for 5G communication to smartphone terminal antennas in element quantity and isolation, an eight-element wideband MIMO antenna set of high isolation level is proposed. Each array a double-L consisting L-shaped slot 50 Ω microstrip line. The L formed by adding I-shaped open circuit directly side rectangular slot. In addition, arrays are located on long bezels both sides mob...

High gain antennas are highly desirable for long-range wireless communication systems. In this paper, a compact, low profile, and high dielectric resonator antenna is proposed, fabricated, experimentally tested, verified. The proposed system has cylindrical with height of 9 mm radius 6.35 as radiating element. sourced slot while the excited rectangular microstrip transmission line. line designe...

As known, to finish this book, you may not need to get it at once in a day. Doing the activities along the day may make you feel so bored. If you try to force reading, you may prefer to do other entertaining activities. But, one of concepts we want you to have this book is that it will not make you feel bored. Feeling bored when reading will be only unless you don't like the book. test and diag...

In this paper, a hybrid dual-band cylindrical dielectric resonator antenna with parasitic slot fed by a microstrip line that is suitable for wireless body area network is proposed. In this configuration, the dielectric resonator performs the functions of an effective radiator along with the feeding structure and the slot in the ground plane. By optimizing the structural parameters, the antenna ...

Hollow-waveguide slot array antennas [1] have been widely used in the milli-meter band since they do have neither radiation loss nor dielectric loss. Furthermore, they have been developed especially for military application such as radars. For commercial application such as fixed wires access system, mass production at low cost has been required and single layer hollow-waveguide slot array ante...

Novel circularly polarized antennas with a circular radiating aperture for broadband characteristics are presented in this paper. The vertical and horizontal components of the L-shaped probe are separated and placed at the front and back side of the substrate. The antennas are excited by a microstrip line which is connected to the vertical component of the L-shaped probe and electromagnetically...

A numerical design tool has been used to design a halfsplit CDR antenna excited by a coaxial prohe which promises improved bandwidth, radiation efficiency, and power handling capabilities as compared to conventional microstrip and slot-coupled transmission line antennas. Although results were presented only for the TEo, and HEM,, modes, other quasi-TE modes can be excited using this configuration.
