3591/01 LNB Antenna, 24.25 to 29.5 GHz, dir.

When measuring inside buildings, the field strengths are often very low. For

example, a modern, coated glass window can attenuate a signal at 24 GHz by

about 30 dB. To be able to detect a field strength of such a low level, a high gain

antenna is needed. In turn high gain antennas have a high directivity due to their

design. The LNB antenna 3591/01 is a directive antenna with high gain.

In addition, the directional characteristic can be used to detect the field

strength of geographically separated base stations. Depending on how the

antenna is held, it receives primarily horizontally or vertically polarized RF

signals. A label on the antenna indicates the polarization.

3591/02 LNB Antenna, 24.25 to 29.5 GHz, omn.

For EMF measurements, national and international standard recommenda-

tions require EMF measurements to be performed isotropically. However,

isotropic antennas are not available for the FR2 frequency range.

The LNB antenna 3591/02 offers an omnidirectional characteristic that

roughly corresponds to the shape of a donut, which is as close as you get to

an isotropic characteristic in the FR2 frequency range. Ideal results with the

3591/02 antenna are therefore obtained in an X-Y spatial plane. To cover all

three spatial axes for isotropic measurements, the antenna must be moved

accordingly during the measurement.

To move the antenna easily, the antenna must be connected to the basic

unit via an extension cable.

 The omnidirectional LNB antenna has its minimum in axial direction

(donut shape antenna pattern). Therefore, do not align the antenna

axially with the RF source during the measurement, as this will create

significantly underestimated results!
