Amateur radio is the only hobby that offers its licensed operators the chance to legally design, build, and operate high power radio transceivers connected to unlimited antenna arrays for the purpose ...

Note: we are working to recover the figures for this article. The process of designing a short-range radio system can be complex and often involves many project tradeoffs (Fig. 1). With a little ...

The basic design of the radio antenna hasn’t changed in a century. The antenna is usually a set of metal rods roughly half the size of the wavelength they are designed to receive. The electric field ...

THE ANTENNA. This crucial component of any radio transmitting or receiving system has a history that actually predates the invention of radio itself. The first antennas were used by Princeton ...

After my recent Jensen JHD-910 radio article was posted on webBikeWorld, an astute reader commented about the importance of the antenna. He and radio pioneer Marconi were absolutely correct, in that ...

The whip or pole car antennas of the past have all but disappeared in the latest models. Car designers simply won’t use them anymore because of esthetics as well as wind noise and drag issues. These ...

From 5G smartphones to IoT sensors, RF antennas are the backbone of modern wireless systems. Selecting, designing, and tuning them precisely ensures reliability, efficiency, and compliance. Here’s how ...

The process of designing a radio system can be complex and often involves many project tradeoffs. With a little insight, balancing these various characteristics can make the job of designing a radio ...
