INTERNSHIP - Characterization of OTA (Over-The-Air) load-pull effects of a multi-port antenna - M/F

This internship at Thales' Elancourt site, a major technological excellence center in Saint Quentin en Yvelines, involves joining the "Antennas, AESA and Radiated IVV" team within the Defense Mission Systems entity. The role builds upon a previous 2025 internship where an OTA load-pull measurement bench was designed and implemented. The primary objective for this 2026 internship is to utilize this bench to characterize the load-pull effects of a multi-port antenna.

Must Have

• Simulate a multi-port antenna (based on an existing design) to understand its challenges
• Develop the test strategy
• Implement tests using the bench developed in 2025

Good to Have

• Knowledge of Matlab or Python programming
• Knowledge of antenna simulation software (HFSS or CST)

Perks & Benefits

• Technological expertise
• Focus on employee work-life balance
• Inclusive and benevolent environment
• Recognized societal and environmental commitment (Thales Solidarity, CAC 40 ESG…)
• All our internships are formalized and subject to remuneration determined by your level of study.

You will join the "Antennas, AESA and Radiated IVV" team of the Defense Mission Systems entity, which has a material characterization bench.

You will work within the "Antennas, AESA, and Radiated IVV" team whose main activities concern:

• antenna and stealth studies (upstream and projects)
• design of antennas, AESA, and radomes
• measurement of antennas and AESA
• RCS characterization
• material and radome characterization

The internship is part of the continuation of a 2025 internship, during which an OTA (Over-The-Air) load-pull effect measurement bench was designed and implemented.

The objective of this 2026 internship is to use this bench to characterize the load-pull effects of a multi-port antenna.

By joining us, you will be entrusted with the following missions:

• Simulation of a multi-port antenna (based on an existing design) to understand its challenges
• Development of the test strategy
• Implementation of tests using the bench developed in 2025
