Description

Purpose of the Role:

System Antenna Engineers are responsible for designing the phased array antenna beams for ALL.SPACE satellite terminals whose RF performance meets market needs. They work within the overall system architecture, designing specific antenna RF functionality via requirements, antenna RF modelling and chamber-based testing as appropriate.

Roles and Responsibilities

Understand the overall system architecture and RF functionality:
Understand the end-to-end system design and RF architecture
Analyse and improve any existing system documentation
Engaging with relevant stakeholders to refine the architecture
Design Antenna Beam Patterns via:
Use of Ansys HFSS modelling tools and plug-in scripts
Matlab modelling of Antenna RF performance
Python modelling as needed
Simulation results generation, capture and visualisation
Refine and improve Antenna Beam Patterns via:
Running real-world RF chamber tests
Investigate and understand the variances between simulation and chamber results
Determine the consequences of manufacturing variances on RF performance
Refine the models to reduce any variances found
Produce specifications for the Hardware, Firmware and Software teams, using RF design conclusions to drive RF layout, FPGA and software design
Detailed reporting on all activities, suitable to drive internal decision making, and inform external partners
Management of High-Performance Compute servers
Advise and support other engineering teams on Antenna testing scenarios and criteria

Candidate must hold a degree in a Physics (or closely related) Bachelor, Masters, or Ph.D. program.
