Most radio engineers today will recall uncomfortable evenings and cold nights spent in dog houses making antenna impedance measurements, or worse, still trying to balance a laboratory model GR bridge ...

St. Louis, Mo.—Laird Technologies has enhanced RadioAnt with Activv, an FM antenna that is embedded directly into a handset to improve performance, minimize product size, ease installation and lower ...

This 4-part report discusses antenna fundamentals and the various types of antennas used for short range devices. Fundamentals are presented along with practical design principals. It is excerpted ...

In this paper a new formula for the input impedance of the rectangular V-dipole antenna is presented. The formula is derived by variational method using a two-term trial function for current ...

ADELPHI, Md. -- A new, miniature, low-frequency antenna with enhanced bandwidth will enable robust networking among compact, mobile robots in complex environments. In a collaborative effort between ...

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 ...

Atmel(R) Corporation (Nasdaq: ATML) announced today the availability of the highly integrated AM/FM antenna amplifier IC ATR4251, which enables outstanding AM/FM car-radio reception when used with ...

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 ...

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 ...

So far in the $50 Ham series, I’ve concentrated mainly on the VHF and UHF bands. The reason for this has to do mainly with FCC rules, which largely restrict Technician-level licensees to those bands.
