In this paper we present the electromagnetic modeling and beam pattern measurements of a 16-elements ultra wideband sparse random test array for the low frequency instrument of the Square Kilometer Array telescope. We discuss the importance of a small array test platform for the development of technologies and techniques towards the final telescope, highlighting the most relevant aspects of its design. We also describe the electromagnetic simulations and modeling work as well as the embeddedelement and array pattern measurements using an Unmanned Aerial Vehicle system. The latter are helpful both for the validation of the models and the design as well as for the future instrumental calibration of the telescope thanks to the stable, accurate and strong radio frequency signal transmitted by the UAV. At this stage of the design, these measurements have shown a general agreement between experimental results and numerical data and have revealed the localized effect of un-calibrated cable lengths in the inner side-lobes of the array pattern.

Abstract-This work provides the comparison of different methods for the experimental determination of the phase center location of an antenna. The phase center position is determined by means of measured data obtained with a planar scanning system and computed with different methods: a least-squares fit method with and without weighting coefficients and a directivity-based plane wave spectrum (PWS) analysis method. A study of the phase center position for different microwave antennas is provided. The results of the different methods are presented and compared, along with the confidence interval of the phase center values due to the uncertainties of the acquisition system.

Feed based scanning Antenna Pattern Comparison (APC) is a method to improve antenna measurement accuracy similar to the well-known APC method. In contrast to APC, the transmit antenna (feed) is moved instead of the AUT. This is beneficial because moving the feed is in general easier than moving the AUT. Previous publications have shown that horizontal feed based scanning APC and APC show similar improvements. Feed based scanning APC can easily be extended to two dimensions and this paper presents a comparison between horizontal and vertical feed scanning directions. For the comparison the technique was applied to measurements of a high and a medium gain antenna as well as Quiet Zone (QZ) measurements in a single reflector Compact Antenna Test Range. It is shown that different feed scanning directions require different mechanical alignment capabilities. Furthermore, it is pointed out that depending on the measurement setup, the AUT characteristic and the underlying scattering sources, the feed scanning direction is a crucial parameter. Thus the feed scanning direction has to be considered in the usage of the feed based scanning APC technique.
