Antenna Design Engineer

Job Title: Antenna Design Engineer
Location: Hybrid (3 days on-site)
Reporting To: Engineering Manager / Technical Lead

Overview
We are looking for an experienced Antenna Design Engineer to support the development of high-performance electronic-scanning array antenna systems operating in the Ku-band frequency range (15–18 GHz), specifically focusing on radar applications. This role will involve the design, simulation, prototyping, and validation of advanced antenna solutions for next-generation sensing and communication systems. The ideal candidate will bring a solid grounding in RF engineering principles, practical antenna development experience, and a collaborative approach to multidisciplinary engineering. This is a long-term opportunity to develop new antenna designs and evolve our existing e-scan antennas with the aim of enhancing capabilities and performance while driving down the cost of manufacture.

Key Responsibilities:

* Design and develop antennas and antenna subsystems for Ku-band radar applications, including arrays, reflectors, planar and meta-structures.

* Perform electromagnetic (EM) simulation and modelling using industry-standard tools (e.g. EMPRO, ADS, CST, HFSS, FEKO).

* Translate system-level requirements into antenna specifications and detailed designs.

* Conduct performance optimisation for gain, bandwidth, efficiency, beam shaping, and sidelobe levels.

* Support prototyping and manufacturing activities including fabrication oversight and test setup definition.

* Carry out antenna measurements (e.g., anechoic chamber testing, near-field/far-field measurements) and analyse results.

* Collaborate with RF, mechanical, and systems engineering teams to ensure integration and performance compliance.

* Contribute to design reviews, technical documentation, and verification reports.

* Stay up to date with advances in antenna technologies, materials, and design methodologies.

Key Requirements:

* Degree in Electrical/Electronic Engineering, Physics, or a related discipline.

* Proven experience designing and developing RF/microwave antennas.

* Strong understanding of electromagnetic theory, transmission lines, and RF propagation.

* Experience with antenna simulation tools

* Familiarity with Ku-band or adjacent microwave frequency ranges (e.g., X-band, Ka-band).

* Practical experience with antenna measurement techniques and RF test equipment (e.g., VNAs, spectrum analysers).

* Ability to interpret and analyse complex technical data.

* Strong problem-solving skills and attention to detail.

Desirable Experience

* Experience working on radar systems or advanced communications systems.

* Exposure to advanced antenna techniques such as phased arrays, beamforming techniques

* Experience using Matlab, Systemvue and Solidworks Interface

* Familiarity with meta-material or meta-surface-based antenna designs at microwave frequencies

* Understanding of manufacturing considerations for high-frequency antenna structures.

Personal Attributes

* Effective communicator with the ability to work across multidisciplinary teams.

* Proactive and self-motivated, with strong ownership of deliverables.

* Comfortable balancing theoretical analysis with practical engineering constraints.

* Adaptable and open to new technologies and approaches.
