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 ...

Micrel Semiconductor has developed a single-chip radio transmitter for unlicensed bands in the 280 to 460MHz range that automatically corrects for differences in a connected loop antenna so the board ...

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 ...

While we can’t argue that FM has superior audio quality and digital streaming allows even higher quality in addition to worldwide access, there’s still something magic about hearing a weak and fading ...

Last month I wrote some about making a notch filter for the AM band. However, before you have any signals to notch out, you must first, of course, have some signal to begin with. Let’s talk a little ...

Abstract: A mechanically-tuned electrically small loop antenna for HF use is proposed. The antenna is composed of a tuned outer loop that is inductively coupled to a smaller coaxial loop. Measurements ...

Abstract: This article presents a novel superstrate-loaded frequency-agile cavity-backed slot antenna (CBSA) and filtenna for X-band (8–12 GHz) applications. The antenna is designed by combining the ...

I just picked up an "Advent" 27" HDTV from Worst Return.<br><br>Looks pretty damn nice, and after the 10% coupon I used it was only around $450 + tax. 18 month no interest financing too.<br><br>The ...
