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, ...

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 ...

ANGOLA, N.Y., Nov. 19, 2025 (GLOBE NEWSWIRE) -- TX RX Systems is introducing a refreshed line of dipole and stacked dipole array antennas designed for customers who depend on reliable communication in ...

Meaning "two poles," a dipole antenna is the simplest type of antenna, consisting of an electrically conducting wire or rod one half the length of the maximum desired wavelength. The wire or rod is ...

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 ...

Full-sized EMI antennas can be relatively large and expensive, so the question many companies that want to bring radiated emissions pre-compliance testing in-house ask is, “Isn’t there something ...

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 ...
