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 ...

The only way to determine the characteristics of an antenna is to measure its performance since theory alone cannot predict the actual results. The fields generated by antennas are extremely complex ...

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 magnetic loop antenna is a familiar sight in radio amateur circles as a means to pack a high performance HF antenna into a small space. It takes the form of a large single-turn coil made into a ...

QuantalRF, a developer of radio frequency (RF) semiconductor and antenna solutions, announced its DockOn antennas are now ...

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 ...
