Antenna Design Optimization with HFSS and ADS

I'm looking for an experienced RF engineer to revise and improve an antenna's feed network and design for enhanced gain using HFSS and ADS software.

Key tasks include:
- Feed Network Optimization
- Impedance matching: Improve impedance matching using techniques like L-network, quarter-wave transformer, or stub matching.

- Antenna Element Design
- Redesign antenna elements to enhance overall gain.

- Antenna Array Configuration
- Optimize the configuration of the antenna array for better performance.

Ideal Skills and Experience:
- Proficiency in HFSS and ADS
- Strong background in RF design and antenna theory
- Experience with impedance matching techniques
- Ability to analyze and improve gain
