Microstrip patch antennas can be fed by a variety of methods. These methods can be classified into two categories-contacting and non-contacting. In the contacting method, the RF power is fed directly ...

Radio frequency (RF) probes designed like by microstrip patch antennas create uniform and strong magnetic field in high frequency MRI machines, unlike convention coil and bird cage shaped coils used ...

High-resolution magnetic resonance imaging (MRI) machines can work better by changing the structure of radio probes from coils to antennas. How can you make a high-frequency MRI machine more precise?

Antennas made of carbon nanotube films are just as efficient as copper for wireless applications, according to researchers at Rice University’s Brown School of Engineering. They’re also tougher, more ...

We examine the antenna designs that provide GPS functionality to mobile phones and why most phones still do not provide GPS operation indoors. We also see what it will take to make them better. WHAT ...
