  This paper deals with the calibration of the analogue chains of a Square
Kilometre Array (SKA) phased aperture array station, using embedded element
patterns (one per antenna in the array, thus accounting for the full effects of
mutual coupling) or average element patterns to generate model visibilities.
The array is composed of 256 log-periodic dipole array antennas. A simulator
capable of generating such per-baseline model visibility correlation matrices
was implemented, which allowed for a direct comparison of calibration results
using StEFCal (Statistically Efficient and Fast Calibration) with both pattern
types. Calibrating the array with StEFCal using simulator-generated model
visibilities was successful and thus constitutes a possible routine for
calibration of an SKA phase aperture array station. In addition, results
indicate that there was no significant advantage in calibrating with embedded
element patterns, with StEFCal successfully retrieving similar per-element
coefficients with model visibilities generated with either pattern type. This
can be of significant importance for mitigating computational costs for
calibration, particularly for the consideration of real-time calibration
strategies. Data from the AAVS-1 (Aperture Array Verification System 1)
prototype station in Western Australia was used for demonstration purposes.
