A.H. Systems SAS-585 Standard Gain Horn Antenna

INTRODUCTION

The SAS-585 Standard Gain Horn Antenna is designed specifically for utilization in

emissions and immunity testing over the frequency range of 8.2 GHz to 12.4 GHz.

and a constant antenna factor. The antenna performance is very precise and

predictable through design parameters and comparisons of measured versus

computed antenna factors and gain have been shown to be +/- 0.5 dB. Therefore,

this horn antenna is considered to be a standard reference, similar to that of a

resonant dipole below 1 GHz. The coax-to-waveguide adapter is the only power-

limiting component on the antenna and can be removed if high fields are desired.

GENERAL DESCRIPTION

The SAS-585 Standard Gain Horn Antenna mounts directly to the tripod azimuth

and elevation head (AEH-510) at the bottom of the antenna. Horizontal and vertical

polarization is obtained by rotating the antenna on the tripod. The azimuth and

elevation head also allows the operator to vary the antenna azimuth (left right

direction) and elevation (up, down direction) and makes it easy to change the

antenna polarity (horizontal or vertical).

To obtain the field strength of the signal being measured, the operator must add the

receiver reading in dBuV, the antenna factor in dB, and the cable attenuation in dB.

This yields the field strength in dBuV/m. Calibrations for the E-field antennas are

supplied at 1 meter.
