Vertical Multiband HF Antenna Simulation and Analysis with Report - 12/09/2025 05:11 EDT
Budget: €200 – €250 EUR
HF Multiband Vertical Antenna Simulation with Capacitive Hat, need analysis simulation files, 3D model and report of simulation.
Description:
Looking for a freelancer with antenna design expertise (better if experience is non HF antennas) to carry out the simulation of a new vertical multiband HF antenna design with 7 bands.
I can provide photos and hand drawings that describe the antenna structure.
NDA and IP required.
Project will be conducted in milestones (draft, revision, final) before awarding the total budget mentioned in the project.
Antenna details:
Type: Vertical
Total height: approx. 9 meters
Operating frequencies: 7 bands (7MHz, 14 MHz, 18 MHz, 21 MHz, 24MHz, 28 MHz, and 50 MHz)
Structure: Capacitive hat on top
Ground system: Radials and counterpoise
Simulation environment: realistic ground conditions (dry, humid and normal/salt water ground plane) in 3 different heights from ground.
Scope of work:
Antenna modeling
Analysis for all operating bands including radiation patterns (2D/3D), Impedance and SWR vs frequency, Gain and efficiency, Influence of ground and radial system with different types of soil and three different heights from ground.
Deliverables:
Antenna model 3D file (detailed)
Simulation files (including radiation patterns, efficiency, VSWR / Return loss) for each type of ground and height required.
Report with approach used for the analysis, data results and plots / graphs
Timeline:
Preferred delivery: within 5–8 days after project confirmation
