There is no way to cover all the important concepts of directional antennas in a single column. There have been many voluminous tomes written about this subject. This month we will look at some of the ...

An antenna is an electrical component that is needed to transmit and receive electromagnetic energy from the space surrounding it in order to establish a wireless connection between two or more ...

In the United States and many parts of the world, antennas are calibrated per the American National Standards Institute C63.5: American National Standard for Electromagnetic Compatibility—Radiated ...

Like a lot of people, [Bruce] likes radio controlled (RC) vehicles. In fact, many people get started in electronics motivated by their interest in RC. Maybe that’s why [Bruce] did a video about ...

If you need to characterize RFID tags or make reflection or stimulus/response measurements on antennas or transceiver modules, you might be able to make use of a low-cost basic spectrum analyzer.
