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 ...

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 ...

Today, miniaturized devices require the use of antennas that are smaller than their wavelength. Wide bandwidth microstrip antennas get a lot of interest from designers due to their flexibility and ...

When it comes to actual antennas in the real world, much of our knowledge is empirical. We know very broadly theories that explain how a point charge radiates (Maxwell’s equations), the need for ...
