A significant performance element in communication and radar systems, as well as wireless devices, is the antenna, which may be defined as a transducer between a guided electromagnetic (EM) wave ...

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 ...

This article was written by Louis Frenzel, author of Principles of Electronic Communications Systems, that addresses this topic and much more. Antennas are much more than simple devices connected to ...

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 ...

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 ...
