Antenna Measurement/Evaluation System

Model No. XAM

Various antenna measurement techniques have been reported recently. Always keeping up with the latest trend, KEYCOM has been developing superior antenna technologies in the field of 1MHz~300GHz (VHF, UHF, microwave, millimeter wave).

We can design and manufacture various antenna evaluation systems upon request (even single quantity is available).

1. Antenna Measurement/Evaluation System

1.1. Near-Field Antenna Measurement System [ANM01]

1.2. Cylinder type, Near field Antenna Measurement System [ANM02]

The system performs measurement in the near field and converts it to far field and aperture distribution at any distance.

The electric actuator enables vertical movement of the probe antenna, combined with rotational movement of the antenna, to perform cylindrical near-field measurements and conversion to far-field. By adding the horizontal movement option, planar near-field measurement is also possible.

1.3. Compact Range Antenna Measurement System[ANT49]

1.4. Far-field antenna pattern Measurement System [ANT41]

The system evaluates the characteristics of a compact range antenna, using parabolic reflector. This makes the measurement system smaller.

The system can perform measurement in the far-field greater than (1/2π) of the wavelength λ of the electromagnetic wave. We also offer a program to measure antenna patterns by rotating the antenna in azimuth / elevation directions.

1.5. Axis ratio measurment system (For circularly-polarized wave) [ANT90]

1.6. 2D type Anntenna pattern profile measurement system [ANM04]

This system is for measuring polarization isolation.

The system measures antenna pattern in the horizontal and vertical directions in 0.1 degree steps in the far field greater than (1/2π) of the wavelength λ of electromagnetic wave

2. Tools(Fixtures etc.)

	2.1. Antenna Pole [ANT09]		2.2. Antenna Fixture [ANT10]
	This pole is mainly used for evaluating antenna patterns and other characteristics, and can be set at any height, direction, and inclination. The material used is plastic, so there is almost no interference from electromagnetic waves.		The antenna is attached to the antenna fixture and can be adjusted manually for precise positioning and rotation.

	2.3. Automatic Antenna Rotation Drive Unit [ANT11]		2.4. Recording System for Azimuth and Elevation Angle of incoming Radio Wave [ANT12]
	Rotation drive unit for automatic measurement, operated by antenna pattern measurement program.		This system automatically records incoming radio waves by azimuth and elevation angle. Rotation of the polarization plane can be done manually.
