The magnetic loop antenna is a familiar sight in radio amateur circles as a means to pack a high performance HF antenna into ...

AM reception can be very difficult because of the inherent succeptibility AM has to electrical noise and other sources of interference. The built-in antenna in most receivers – a coil and a ferrite ...

Magnetic loop antennas are great if you are limited on space since they are just a potentially small loop of wire. The problem is, they are sharply tuned. You normally have an adjustment capacitor to ...

An introduction to properties of individual antennas and arrays of antennas. Retarded potentials, dipoles of arbitrary length, radiation pattern, gain, directivity, radiation resistance. The loop ...

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 ...

The author is vice president of business development for Orban Labs Inc. Over the last 20 years or so, I have put in several FM master antenna systems in various broadcast facilities, to drive ...

Frequency Modulated (FM) radio has been used for years in high-fidelity music and speech broadcasting, offering excellent sound quality, signal robustness, and noise immunity. Recently, FM radio has ...

From early mobile phones to the IoT, wireless and antenna design has contributed to the evolution of comms. Colin Newman reflects on his company’s history, and future prospects. Changes in antenna ...

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 ...
