A dipole antenna is easy, right? Two wires, each a quarter wavelength long, emanate from a coax or other feedline. Unless it is an off-center dipole. The length is still the same, but you move the ...

Antennas are an essential part of radio telecommunications equipment, bridging the gap between electronic and electromagnetic signals. The shape and size of an antenna is a strong clue as to its type, ...

How may radios do you own? Forget the AM/FM, GMRS/FRS radios you listen to or communicate with. We’re talking about the multiple radios and antennas in your phone, your TV, your car, your garage door ...

Quectel Wireless Solutions, an end-to-end global IoT solutions provider, has unveiled five new durable fiberglass antennas, covering LoRa, V2X, Wi-Fi and 5G technologies. The new antennas augment ...

A dipole antenna using antenna traps is desired which is to be used to transmit a 140 MHz signal and a 90 MHz signal. Design the antenna assuming a velocity factor of 0.90. First find the wavelengths ...

After moving and installing an anechoic chamber, we needed to test the shielding effectiveness. We decided to build a matched set of 900 MHz Dipole antennas. We started by designing a half wave dipole ...

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 ...
