Simulation of 5G mmWave Beamforming Antenna Array for Remote Base Station Applications

Project Description

We are hiring a freelance antenna engineer to design and simulate a beam-steerable phased array antenna operating in the 26–28 GHz mmWave band, suitable for compact 5G remote or fixed wireless access (FWA) base stations.

The project is simulation-only and must include beam steering capability across ±45° with minimal gain drop, low sidelobes, and clear main lobe direction control. The array should be planar and optimized for PCB or LTCC integration.

Objectives:

• Design an antenna array (e.g., patch, slot, or dipole elements) operating at:
  • Center frequency: 27 GHz
  • Bandwidth: ≥ 1 GHz
•  Simulate beam steering between ±45° azimuth
• Optimize for:
  • Gain: ≥ 12 dBi (broadside)
  • Sidelobe level: ≤ –13 dB
  • Return loss: ≤ –10 dB over the entire band
  • Phase uniformity and steering angle accuracy
•  Analyze performance in free space and optional dielectric backplane

Deliverables:

• 3D EM simulation model (CST, HFSS, FEKO, or equivalent)
• Beam steering simulations for multiple angles
• S-parameter plots and radiation pattern visuals (2D/3D)
• Array factor vs angle graphs
• Technical documentation (5–8 pages) covering:
  • Element design and layout
  • Array spacing justification
  • Steering mechanism description
  • Gain, beamwidth, and sidelobe analysis

Recommended Tools:

• CST Microwave Studio
• Ansys HFSS
• Altair FEKO

Ideal Freelancer Profile:

• Experience with phased array antennas and mmWave simulations
• Familiar with 5G NR frequency bands and applications
• Can work independently and deliver clean technical reports
• Understands challenges of beam steering and element coupling

Timeline: 3–4 weeks total

How to Apply:

Please include:

• Your preferred simulation software
• Example of past phased array or mmWave antenna work
• Suggested element spacing and layout format
• Estimated delivery time and your pricing
