Antenna Design Engineer II

RTX RTX · Aerospace · mckinney, TX +1 · Engineering

RTX is seeking an Antenna Design Engineer II to support the development of advanced LO antennas and ultra-wideband phased arrays. The role involves using CEM software to design, model, and predict antenna performance, participating in testing, and supporting prototyping and integration. Requires a STEM Bachelor's degree and relevant RF engineering experience, with a strong preference for an MS/PhD in Electrical Engineering with an RF/Microwave concentration. A security clearance is required.

What you'd actually do

  1. Provide technical solutions to a wide range of challenging problems involving antenna and AESA based applications such as radar, electronic warfare, communications, and direction finding.
  2. 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 (TCDA).
  3. Create, refine, and optimize antenna designs using full‑wave solvers, run parametric studies, and balance electrical, mechanical, LO, and environmental constraints.
  4. Perform EM simulation and/or test to verify compliance with antenna‑level and system‑level requirements, performing root‑cause investigations when issues arise.
  5. Participate in testing of RF hardware for key performance metrics such as VSWR, insertion loss, gain, efficiency, polarization, and radar cross section (RCS).

Skills

Required
