SAGE Millimeter offers many aperture antennas. The popular ones are: There are two common questions we often receive from our customers: Do we have 30 dB or higher gain rectangular or conical horn antennas? Do lens corrected antennas make the beamwidth narrower? In this post we will address these questions. Do we have 30 dB … Continue reading Rectangular Horns, Conical Horns, and Lens Corrected Antennas
The corner reflector is a passive device used to directly reflect radio waves back toward the emission source. Therefore, the corner reflector is a useful device for radar system calibration. In general, the corner reflector consists of mutually intersected perpendicular plates. The commonly seen corner reflectors are dihedral and trihedral. While the dihedral corner reflector is … Continue reading Corner Reflectors
Measuring antenna pattern and gain accurately is often a challenge. It is not only due to the demand of expensive test equipment, but also the requirement of skilled and knowledgeable workers. In addition, it is impossible to avoid the interactions introduced by the test equipment and test fixtures/equipment holders. Unlike most microwave component testing, antenna … Continue reading Which is Better: Simulated or Measured Performance for Simple Antennas?
