Job Description

Job Summary
Job & Company Description:
Looking for an outside-the-box thinking professional to join a diversified team of go getters on as a Radio Frequency Engineer (Cellular Antennas). The successful candidate to fill this role will compile reports, research, design, and develop Antennas, and be a part of the development of tools for obtaining, processing, and simulation results. This person will be the liaison between the Lead RF Engineer and the rest of the research and development team.
Key responsibilities include:
Antenna Design & Simulation

• Use software tools (CST, HFSS, FEKO, ADS) to design and model cellular antennas (2G, 3G, 4G/LTE, 5G).
• Optimise antenna parameters such as VSWR, gain, directivity, radiation patterns, bandwidth, efficiency, and MIMO configurations.

Testing & Measurement

• Perform lab measurements using RF test equipment (vector network analyzers, spectrum analyzers, signal generators, anechoic chambers).
• Validate antenna performance against design simulations and industry standards (ETSI, 3GPP, FCC).
• Conduct over-the-air (OTA) testing to verify real-world performance.

Prototyping & Development

• Build and refine antenna prototypes (PCB antennas, patch antennas, omni/sector panels, base station antennas).
• Work with mechanical engineers to integrate antennas into enclosures while maintaining performance.

Troubleshooting & Optimisation

• Diagnose performance issues such as poor return loss, low efficiency, or pattern distortion.
• Recommend design modifications and retest until specifications are met.

Documentation & Reporting

• Prepare technical documentation (test reports, design notes, compliance reports).
• Support certification processes by compiling compliance test data.

Collaboration & Project Support

• Work closely with cross-functional teams (R&D, manufacturing, quality assurance, and sales).
• Support customer-specific antenna requirements or customisation projects.
• Provide technical support during product deployment and field trials.

The requirements:
Education & Qualifications

• Bachelor's degree in electrical/Electronic Engineering, Telecommunications, or related field (Master's advantageous).
• Specialized coursework or certifications in RF engineering, antenna design, or wireless communications.

Technical Skills and Experience:

• 3-5+ years of hands-on experience in RF design and testing, with a focus on cellular technologies (2G, 3G, 4G/LTE, 5G).
• Strong background in antenna theory, propagation, and design methodologies.
• Proficiency with simulation and modelling tools such as CST Microwave Studio, HFSS, ADS, or FEKO.
• Experience with RF test equipment (network analyzers, spectrum analyzers, anechoic chambers).
• Knowledge of compliance standards and certification processes for cellular antennas (e.g., ETSI, 3GPP, FCC).
• Practical experience in optimizing antenna performance (VSWR, gain, efficiency, MIMO, beamforming).
• Familiarity with ruggedized / outdoor antenna applications for industries like defence, mining, or telecom
