It’s a skill that radio amateurs pick up over years but which it sometimes comes as a surprise to find that is not shared by everyone, the ability to casually glance at an antenna on a mast or a ...

Maximum transmission efficiency occurs when the load impedance matches the generator impedance. Engineers do this to eliminate standing waves, which can severely damage equipment. Transmission lines ...

New understanding of the nature of electromagnetism could lead to antennas small enough to fit on computer chips -- the 'last frontier' of semiconductor design -- and could help identify the points ...

You have probably heard the statement about standing wave ratio: “I changed the length of the transmission line and reduced the SWR.” Or the opposite statement, “I changed the length of the ...

The ultra-wideband, omnidirectional circular ring antenna has a height of 0.047 times the low-frequency wavelength and a width of 0.19 times the wavelength, offering an impedance bandwidth of 12:1.

Every wireless device needs an antenna. This conductive mechanical device is the transducer that converts the radio frequency (RF) power to be transmitted into the electric and magnetic fields that ...

In this application note we will explore antenna theory and design using EZNEC, an easy-to-use antenna simulator. We will measure the antenna’s characteristic impedance through our application board.

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 ...
