“…This option was rejected as adding additional components between the elements and the LNA would impair the noise performance. Another alternative was to place radiators near the PAF [13]. This was rejected as the variation in received signal is expected to be as much as 60 dB.…”

This paper gives an overview on different research activities on electronically steerable antennas at Ka-band within the framework of the SANTANA project. In addition, it gives an outlook on future objectives, namely the perspective of testing SANTANA technologies with the projected German research satellite "Heinrich Hertz". modem information source, e.g. internet earthstation modem end user, e.g. PC Rx Tx fBE=18.2-20.2 GHz transponder Heinrich-Hertz satellite high data rate communication mobile terminal circular polarisation satellite modem fTS=29.5-30.0 GHz fTE=19.7-20.2 GHz fBS=28.0-30.0 GHz

“…Some methods are proposed to calibrate receiver arrays only and radiation sources at multiple positions are needed [8][9][10]. Some other methods obtain the element signals by measuring the array signals with the measurement probes at multiple positions [11][12][13][14][15][16][17]. Planar near-field measurements are required in [11][12][13][14] and far-field radiation patterns are measured in [16][17].…”

In this paper, we propose a new phased array calibration method that measures all antenna element excitations simultaneously. The method has the minimum number of measurements among the known similar methods. The auxiliary antenna used for measurement is placed in either near-field or far-field region to receive the complex array signals during the change of the antenna element phase settings. According to the superposition principle of electromagnetic field, a set of linear equations concerning the element signals are created with the measured array signals. With the scattering parameters between the measurement probe antenna and the element antennas pre-stored or simplified, we calculate the excitations of the antenna elements by solving the linear equations. The coefficient matrix of the linear equations determines the antenna element phase settings for the array signal measurements. The principles for the selection of the coefficient matrix concerning accuracy, complexity and hardware requirements are presented. A recursive matrix-forming method is presented for the matrix selection in this paper. Numerical simulations and experiment results validated the effectiveness of the proposed method.
