Antennas are mandatory for a product to connect via radio frequency. Obvious examples are cell phones, satellite communications, and even our garage-door openers. But the Internet of Things is ...

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 ...

There’s a joke in the world of radio that all you need for a HF antenna is a piece of wet string, but the truth is that rudimentary antennas rarely perform well. Random pieces of wire may pull in some ...

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 ...

We had previously reported that LeEco could be planning to release a new smartphone in September around IFA Berlin. While we are not yet 100% sure what to expect at the event, it’s being said that the ...
