Overview

The Mi-Wave 202/203 series are high-gain prime focus parabolic antennas built for a symmetric pattern and stable RF performance from microwave through millimeter-wave. The family covers the X, Ku, K, Ka, Q, U, V, E and W bands, 8.2 to 110 GHz in total, with reflectors of 3, 6, 9, 12, 18, 24, 36 and 48 inches. Gain runs from 26 to 57 dB and rises with diameter and frequency; the 3 dB beamwidth falls between 0.18 and 6.5 degrees. The 202 series uses an aluminum reflector and the 203 a fiberglass composite; both hold VSWR at 1.3:1 and end in the standard waveguide flange for their band. Fix the band first, then pick the diameter for the gain and beamwidth you need, and check that combination exists. Typical uses are satellite communications, radar, antenna ranges, RF laboratories, EMC testing and millimeter-wave research.

Features

High gain across the whole range

X-band to W-band (8.2 to 110 GHz) with gain up to 57 dB, rising with diameter and frequency, for long-range and millimeter-wave links.

Symmetric narrow beam

The prime focus layout gives a symmetric pattern with a 3 dB beamwidth as narrow as 0.18 degrees, for pointing-critical measurement and communication work.

Eight diameters

Reflectors from 3 to 48 inches let you trade gain against beamwidth and physical size for each installation.

Two reflector materials

The 202 series uses a machined aluminum reflector; the 203 series a metallized fiberglass one where weight matters more than surface accuracy.

Stable RF match

VSWR stays at 1.3:1 across the family, and each model ends in the standard waveguide flange for its band, so results repeat.

Broad range of uses

Satellite communications, radar, antenna test ranges, RF laboratories, EMC testing and millimeter-wave research.

Typical applications

Antenna measurement

Far-field millimeter-wave antenna measurement and gain calibration

On an anechoic or open-air range, a 202/203 series reflector serves as the source or receive antenna. High gain and a narrow beam keep multipath low, so engineers measure pattern, gain and sidelobes of the antenna under test from 18 to 110 GHz without long, lossy waveguide runs.

Aerospace and defense

Satellite ground station uplinks and radar system integration

In Ka-band and V/W-band ground terminals and airborne radar prototypes, the prime focus reflector delivers the gain a tight link budget needs with a short feed path. Defense research groups and satellite operators use the 202/203 series to hold a stable uplink EIRP through integration and acceptance testing.

R&D laboratory

5G/6G millimeter-wave propagation and channel model experiments

Universities and carrier R&D teams building channel models for 5G mmWave (28 GHz, 39 GHz) or candidate 6G bands use a 202/203 series antenna as the directional reference radiator. With a vector network analyzer they record path loss, angular spread and cross-polarization ratio to parameterize channel emulators and validate beam management.
