Manufacture of the Transceiver Housing for an Active Phased Array Antenna with Built-In Cooling Channels by Selective Laser Melting
摘要： A cooled transceiver housing of an active phased array antenna is produced by 3D printing from aluminum, on the basis of selective laser melting (SLM). The housing walls contain cooling channels, whose geometry ensures effective heat transfer from the active electronic components of the transceiver and also permits the manufacture of high-quality samples on existing 3D printing systems and facilitates cleaning of the channels after printing. The housing is made of AlSi10Mg aluminum, with an acceptable content of closed pores (no more than 1%). Its physicomechanical properties correspond to those of regular aluminum alloys used in the traditional manufacturing technology for such components. This housing may be used in advanced radar systems. The research permits recommendations for further development of the technology.

[Institution of Engineering and Technology 12th European Conference on Antennas and Propagation (EuCAP 2018) - London, UK (9-13 April 2018)] 12th European Conference on Antennas and Propagation (EuCAP 2018) - Compensation Method for Distorted Active Phased Array Antennas in Condition of Quantization Errors Based on Structural-Electromagnetic Coupling
摘要： Widely used digital attenuator and phase shifter could inevitably introduce quantization errors for distorted active phased array antenna, at the time of controlling the amplitude and phase for improving the electromagnetic performance. The reduction of quantization errors decides the compensation effect service for antenna environment. Therefore, a compensation method for distorted antenna in condition of quantization errors is presented based on the coupled structural-electromagnetic model with least squares method. The quantized amplitude and phase adjustments are deduced from the perspective of multiple dividing of minimum quantization value and the optimal amplitude and phase differences, which could be implemented to recover a high quality pattern from a distorted antenna. Lastly, an X-band active phased array antenna with representative saddle shape deformation is illustrated to verify the compensation effect for quantization errors including both the amplitude and phase.
