In this post, we investigate PC board antenna feeds, showing how they work compared to a discreet cable as well as some potential pitfalls in design.

Antenna Performance Issues
It sometimes happens that after incorporating a known-to-be-good antenna into a device, the device fails to perform as hoped. Here are some possibilities as to what can cause this.
Chip Antennas
When using a chip antenna, it is important to keep in mind that most chip antennas are not complete in and of themselves, but rely on PC board geometry in order to function.
Why Antennas Need a Ground Plane
In this post we discuss what the purpose of a ground plane is, how it works with an antenna, and why some antennas require a ground plane while others do not.
Small Loop Antenna Located Over a Ground Plane
An examination of the effects of a groundplane in close proximity to a loop antenna, and how it alters the radiation pattern of the antenna.
