By regulation, the FCC requires any transmitter to suppress spurious emissions. A combination of an isolator and Band Pass Filter (BPF) is one way of meeting this requirement. When combining radios into antenna systems, each transmitter will have an isolator on the output, followed by a combination of filters to deliver all transmitters to the antenna.

ANTENNA TYPES - OVERVIEW

Figure 15 Antenna types

There are various types of antennas. The table on this page identifies several.

Antennas are found in various shapes, sizes, and configurations depending on the application. Antennas are selected based upon their type and characteristics, including directivity and polarization.

In this section of the course, the following antenna types are introduced; some will be covered in depth, examples include:

• Half wave dipole antenna

• Folded dipole antenna

• Yagi antenna

• Corner reflector antenna

• Indoor antenna

• Exposed dipole antenna

• Mobile antenna

• Microwave antenna
