“…4, right). The radiation patterns were measured at 38 GHz for co-and crosspolarizations by the method described in [25]. Figure 9 illustrates the calculated radiation Measurements (the horn with the circular-to-rectangular transition) patterns in the E-, H-, and 45°-planes and measurement results.…”

The requirements for a feed suitable for a radio telescope multi-beam focal plane array are considered. A smooth-walled spline-profile horn covering the 30-38 GHz frequency band to be used in a multi-beam receiving array of a radio telescope has been optimized, manufactured and tested. The achieved cross-section aperture size of the horn allows us to provide a neighboring beam spacing equal or less than 2HPBW for the RATAN-600 radio telescope. The measured sidelobe levels of the radiation pattern is less than−30dB/−24dB/−26dB in H/E/45 0 -planes, cross-polarization levels better than−20 dB, an input return loss better than −18 dB and the −3dB/−10dB-beamwidths are of the order of 40º/ 80º over the frequency band. Mutual-coupling of adjacent horns is less than−38 dB.

“…The radiation patterns were measured on the experimental set-up described in [9], and S 11 parameters were measured on the Agilent Network Analyzer PNA-L N5230A. By taking into account that the measured input reflection coefficient is virtually the same for all sixteen feeds, we show in Fig.6 (up) the S 11 of a one of them.…”

In this paper simulated and measured characteristics of an optimized smooth-walled spline-profile horn for twodimensional multibeam focal plane array at RATAN-600 radio telescope are presented. The measured -10dB beamwidth is less than 45 0 in the H-and E-planes. The measured side-lobe levels of the radiation pattern are less than -18 dB in the both principal planes. The measured input reflection coefficient is better than -21dB in the frequency range 30GHz -38GHz. The experimental results are in good agreement with simulated ones in the operational frequency band 34GHz -38GHz.

“…These experiments were performed with the help of the methods, facilities and special probes developed and designed in the Laboratory of High Frequency Technology and described in detail in our earlier papers [Ivanchenko et al, 2002;Cao et al, 2002;Andrenko et al, 2006;Chernobrovkin et al, 2006;Chernobrovkin et al, 2007]. As an example, the near-field distributions of the quarter-wave monopole antenna with different ground plane radii are shown in Fig.…”
