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.
Why Does the Size of the Antenna Matter?
An explanation on why the size of an antenna is important to the antenna's performance, and how this size constraint can affect the design of a device.
Using Sequential Rotation
In this post we discuss sequential rotations, which is a method by which excellent circular polarization can be implemented into an antenna array, even in wideband applications.
