Antennas are an important part of wireless communication. Antennas facilitate receiving and transmitting signals. To get antennas to function, we have to test them. A measurement system for an antenna assists in testing passive and active antennas. An antenna measurement system is used to check the performance of antennas.
Let us know how the system operates and why we require it.
The system consists of:
- Open a test field or a test chamber
- Signal receiver or generator
- Positioner to shift the antenna
- A Computer with software to capture and analyse results
The system offers precise results in a controlled environment.
System Testing for Types of Antennas
We can test two types of antennas on this system:
- Passive Antennas
Passive antennas do not contain power inside them. They rely on the source of the signal or the device. They are usual in:
- TV antennas
- FM radio antennas
- Simple mobile phone antennas
The system checks the transmission and reception of signals by them using no external power.
- Active Antennas
Active antennas incorporate electronics. They are powered and use power to boost signals. They are employed in:
- GPS technology
- Satellite communications
- Smart cellular phones
The system verifies their performance while in operation.
Why Do We Need to Test Antennas?
Antenna testing confirms that they:
- Work well when put into real usage
- Are in line with design and safety requirements
- Function without signal loss
Minor defects in an antenna can result in weak or lost communication. So, proper testing is required.
How Does the Measurement System Work?
The system operates based on some general steps:
- Mount the antenna onto a positioner – It positions the antenna at various angles.
- Transmit or receive signals – The system tests the antenna’s performance at every angle.
- Log the results – the computer displays signal strength, range, and pattern.
- Performance analysis – Engineers verify if the antenna is up to the required standards.
Key Features of a Good Antenna Measurement System
A good system provides:
- High accuracy
- Quick test results
- Simple setup
- Capability to handle numerous types of antennas
- Complete reports
It must also handle indoor and outdoor tests.
The majority of industries apply antenna measurement systems:
- Telecommunication businesses – for mobile antenna testing
- Defense industries – to ensure radar and communication systems
- Automotive sectors – for testing antennas in cars
- Space industries – for testing aircraft and satellite antennas
An antenna measuring system assists in verifying the function of active and passive antennas. It verifies whether they are according to standard and function as desired under practical application. With greater wireless communication, such systems grow increasingly important. Whatever you do, whether producing simple radios or sophisticated GPS equipment, verifying your antennas with a proper system will contribute to improved functionality and less bother.
