Introduction to Wireless Microphone Systems

Friday, September 18th, 2009

Wireless equipment is perhaps one of the most poorly understood technologies used in the theatre and broadcasting world today.  Despite their complexity, it is possible to develop an intuitive understanding of how these devices work.  The purpose of this document is to explain the fundamental behavior of wireless systems, and to apply this knowledge to the functionality of wireless microphones, wireless in-ear monitors, and similar systems commonly found in the theatre and broadcast industries.  This guide assumes that the reader is familiar with basic electrical concepts such as impedance and electrical waves.

Antennas

Friday, September 18th, 2009

Antennas are passive electrical devices that convert electromagnetic radiation into electrical signals, and vice versa. Both transmitters and receivers require antennas to operate. Transmitters typically have small “whip” antennas mounted on them, and receivers usually have a connector on the rear to attach an external antenna. There are a number of types of antennas commonly used for wireless microphone receivers.
