Основные возможности и технические характеристики
The antenna S12014/5 is a linear polarized log.-periodic antenna with foreshortened radiators used for indoor EMC testing.

This is an exceptionally compact antenna for this frequency range, ideally suited for use in anechoic EMC chambers. Antenna polarization (horizontal or vertical) and elevation angle (0° to -40°) can be manually or remotely adjusted.

The antenna is installed on a dolly with rollers for ease of positioning. Manual or automatic change of polarisation, height and elevation is available as option. An optional remote control unit allows automatic operation of the antenna axes.

Measured Field Strengths
The diagrams show measured field strengths made in various anechoic chambers. The measuring sensor was placed 4 m from the tip of the antenna. The RF input power was 2 kW, the height of the sensor was about 1.5 m. For comparison the calculated values assuming a reflecting ground are also shown. The spread of the measured values is due to the effects of the different chambers and the accuracy of the used sensors.

Measured field strength distribution
Measured field strength distribution at 3 m distance from the antenna tip (vertically polarized). The covered area has dimensions of 1.75m (H) x 2.25 m (W); the antenna height is 1.6 m, the antenna elevation –12°. All measured values are given in dB relative to the beam center. 20 MHz (1st value) 220 MHz (2nd value).

Simulated electric field uniformity
Simulated electric field uniformity for the log.-periodic antenna array S12014/5 at 2 m distance with vertical antenna polarization. The antenna was placed in free space without ground influences. The input power was considered to be 10 kW. The covered area has the dimension 4 m x 4 m. The grid-distance is 0.2 m.

Remote adjustments
A remote control unit S42056/01 is needed. The remote control unit itself can be controlled as a device via RS-232 serial interface or graphical user interface.
The remote control unit is connected to the antenna via fibre optic cables. The control box at the antenna controls the motor for the polarization axis. The remote control unit continuously monitors the actual value of the polarization.

Mains Connector                  Souriau 8.47.25F547N002 (shielded)
Mains Voltage:                      230 V / 50 Hz
Connector for FOC:              2 x ST 62.5/125 µm Multimode

FOC and mains cable with connector are not part of the scope of delivery but available on request.

Detachable Radiators
The overall height of the antenna may require the user to remove the last radiators to enable the antenna to pass through the chamber door, or to minimize storage space required. Optionally the longest radiators can be manufactured to be removable.
