Theoretically, an ideal antenna test

environment should provide a plane wave

testing area without reflection, within this

area, the radiation performance of the

antenna is measured. So antenna test should

meet far field environment conditions.

However, when the antenna is very large

and the working frequency is ultra high, the

test distance will be hundreds or even

thousands meters long, which becomes

unrealistic to test environment and the cost

will be extremely high. Compact Antenna

Test Range (CATR) employs an optical

technology to transform the spherical wave

to plane wave, so as to create a far field test

environment within limited distance and

ensure the amplitude and phase of

electromagnetic wave in the quiet zone are

consistent. In this way, CATR can be

regarded as a regular far field system which

meets the needs of electrically large antenna

measurement at an affordable cost.

CATR technology has been employed

by Aerospace and Defence industry for

many years, for 5G mmwave antenna/OTA

test, CATR has special benefits, it is

functional, accurate, and DUT adaptable.

The CATR uses a parabolic reflector to

collimate spherical wave emitted by a small

radiation source(feeding source) into a plane

wave, so as to form a plane wave radiation

mmWave CATR Chamber

region(quiet zone) in which the amplitude

and phase distribution is almost ideal,

thereby meeting the requirements of far

field testing.

Compared to the traditional far field

and near field test, CATR limits the plane

wave just within the quite zone and the

reflection from surrounding walls is relative

low, therefore, reduces the requirements for

the chamber. Moreover, the in-door test is

less affected by the environment, so its

efficiency is relative high and can be run

24/7. Meanwhile, CATR covers wide working

frequency band, mmwave and sub-mm

wave tests can be done by just changing the

feed antenna. CATR can be applied to

mmwave equipment/antenna measurement,

and it is one of most effective test methods

in 5G FR2. CATR can also be used in

automotive radar antenna measurement.

A CATR chamber system consists of

reflector, feeding source, anechoic chamber,

low reflection 2D turntable, measurement

instruments and test control software. The

performance of CATR become more

stringent with increasing frequency, the parts’

machining and assembly accuracy, especially

the reflector, demands stricter requirements.

Thus, the overall system performance is

determined by the manufacturing and

assembly of reflector, feeding source etc.

short wave length, wide band width and high

resolution, so corrugated horns with narrow

beam width and high gain is the most

suitable feed for CATR systems.

RayPact Major Features

1. High Precision Reflector

Compared to lower frequency, mmwave

has higher pathloss, which brings big

challenges to the manufacturing of mmwave

parts. For example, the reflector’s machining

and assembly precision should reach up to

microns level. Reflector becomes the key

part of a CATR chamber, it’s precision will

affect the whole system’s performance.

RayPact series products adopt the high-end

rolled edge reflector, which has high

precision, stable structure, compact size and

excellent performance.

4. Innovative mmWave Absorber VPC60

RayPact600 equipped with GTS’s high

performance mmwave absorbers, which

are made with closed cell expanded

polypropylene(EPP). The absorbing agent is

directly fused with the PP resin particles,

then foamed at a high temperature. The

final product is uniform, stable, moisture-

free, dust-free and in-deformable and the

absorbing performance for the anechoic

chamber can be promised. The VPC60 is 6

cm height, its reflection within the whole

working frequency band is less than -40dB.

➢ Electrical performance：EPP has small

dielectric constant, small surface

reflection, uniform material, sufficient

internal attenuation and good absorbing

effect in the microwave frequency band.

➢ Flame retardant ：meets UL94 HF-1，

GB8624 B2 standard.

➢ Oxygen index：> 27%

➢ Working temperature ： long-term

50~100℃ (short-term 120℃).

➢ Environmental protection ： non-toxic

raw material, odor-free, and no harmful

gas released.

➢ Final product：stable in nature, meets

RoHS standard.

➢ Physical performance：on-time molding,

precise size, uniform and customizable

color, stable and in-deformable.

3. Fine-tuning Feed Positioner

The feed positioner is an auxiliary

device for adjusting the feed position to

achieve the precise relative position to the

reflector. This six-axis fine-tuning platform

can make the feed move in X,Y, and Z

direction. At the same time, it can rotate

360° in azimuth and 20 ° in polarization.

RayPact CATR test system consists of a reflector, feed, turntable, shielding chamber and

absorbers, system software and RF links. Among these, the reflector works with the feed to

become the core component of CATR –- the plane wave source. The feed’s position is

precisely located and can be finely tuned. The turn table supports 2D rotation and is able to

do the fully spherical scanning and sampling. The shielding chamber with the high

performance mmwave absorbers provides a closed test environment which is a stable and low

electromagnetic noise. The system software and RF links are necessary for the DUT testing. All

the DUT test results can be obtained from the data sampling, software algorithm processing,

data analysis and finally visual graphic displayed.

3. Active Test (Receiver Performance test, non-signaling)

Major applications: phased array base station, mmwave UE receiver performance test,

such as EIS、ACS、Blocking、Intermodulation etc.
