    300 GHz Antenna Testing

    Hello All,

    I have designed a 300 GHz lens antenna and I want to test it. I have ordered its fabrication and its very small, it has to be attached with a lens and a PCB to hold it.

    I have to measure s-parameters and radiation pattern. The antenna chip will also have detector mounted.

    I want to order an antenna positioner/rotator for radiation pattern measurement.

    Can anyone please suggest a company for an accurate (around 0.1 to 0.05-deg accuracy) rotator/positioner for antennas at 300 GHz frequency range?

    The rotator would be for both azimuth and elevation planes.

    Our measurement system has everything required, except a motor/automatic rotator for PCB/antenna.

    Thank you in advance.

    Re: 300 GHz Antenna Testing

    I have doubts about 0.1deg accuracy. I have used commercial rotating table few times, it had stepper motor and a belt. Most important part was the software, which was able to get data from spectrum analyzer. Maybe industrial robotic arm manipulator type will provide 0.1deg.

    Google for "antenna measurement system"
