Antenna Design Engineer II

Overview

We are seeking an Antenna Design Engineer II to support advanced LO antennas and ultra‑wideband phased arrays. This role is ideal for new M.S. EE graduates who excel in both deep technical analysis and hands‑on engineering.

Onsite, 1st shift – 100% on‑site in McKinney, TX.

• Provide technical solutions to challenging problems involving antenna and AESA based applications such as radar, electronic warfare, communications, and direction finding.
• Use advanced computational electromagnetic (CEM) software (HFSS, CST, FEKO, SENTRi) to design, model, and predict performance of antennas and apertures including spiral, sinuous, Vivaldi, patch, slot, horn, and ultra‑wideband tightly coupled dipole arrays.
• Create, refine, and optimize antenna designs using full‑wave solvers, run parametric studies, and balance electrical, mechanical, LO, and environmental constraints.
• Perform EM simulation and/or test to verify compliance with antenna‑level and system‑level requirements, performing root‑cause investigations when issues arise.
• Participate in testing of RF hardware for key performance metrics such as VSWR, insertion loss, gain, efficiency, polarization, and radar cross section (RCS).
• Support antenna prototyping, build reviews, troubleshooting, and integration activities in collaboration with Operations, Manufacturing, and Test Engineering.
• Contribute to internal and customer‑funded research and development programs involving antenna, phased‑array, or RF component/system design.
• Document technical approaches, design decisions, and verification results in engineering reports and formal design reviews.

• Bachelor’s degree in STEM (electrical, mechanical, physics, etc.) and at least 2 years of RF engineering experience in design, fabrication, or testing of conformal antennas, apertures, and passive RF components.
• Experience designing and testing ultra‑wideband phased array antennas such as Tightly Coupled Dipole Arrays, Vivaldi, Sliced Notch, and/or Planar Ultra Wideband Modular Arrays.
• Proficiency with EM modeling tools such as HFSS, CST, FEKO, or SENTRi.
• Experience performing testing with RF equipment including VNAs and far‑field antenna ranges.

• Master’s or Ph.D. in Electrical Engineering with a concentration in RF/Microwave circuits.
• Electromagnetic modeling and simulation experience with conformal antennas or airborne apertures.
• Knowledge of printed wiring board (PWB) or printed circuit board (PCB) fabrication processes, stack‑up design, and design rules.
• Strong written and verbal communication skills supported by publications, technical presentations, or student awards.
• Ability to troubleshoot complex antenna or RF performance issues and collaborate across multidisciplinary teams.
• Experience supporting prototype builds, test automation, fixture design, or specialized antenna range measurements.
