Overview
Rhombic Antenna helps you calculate design values for a specific antenna types project from Frequency, Leg Length (× λ), Included Angle. Calculate approximate dimensions and characteristics of a Rhombic antenna. Use the result to make an informed first design decision before choosing hardware, setting dimensions, or evaluating the RF system in its final environment.
Input Guide
Enter Frequency, Leg Length (× λ), Included Angle exactly in the units shown by this rhombic antenna. Check the operating band, unit prefix, and decimal position before calculating; these are the inputs used by the formula.
- Frequency — use MHz.
- Leg Length (× λ).
- Included Angle — use °.
Output Guide
The results describe the calculated rhombic antenna values for the inputs you entered. Check each value against the available space, selected components, feed system, and operating conditions before making a final design decision.
How This Calculator Works
The Rhombic Antenna uses λ = 300/f Leg Length = λ × Multiplier Overall Length = 2Lcos(θ/2) Overall Width = 2Lsin(θ/2) . Supply Frequency (MHz), Leg Length (× λ), Included Angle (°) in the displayed units, then use the calculated values as the first engineering target for this specific antenna types design or analysis.
Design Notes
This specific antenna types calculation is based on λ = 300/f Leg Length = λ × Multiplier Overall Length = 2Lcos(θ/2) Overall Width = 2Lsin(θ/2) . Real-world accuracy depends on factors such as material properties, losses, mounting, nearby conductors, ground interaction, feed-line effects, and construction tolerance. Confirm the final system with measurement or simulation.
Build and Tuning Notes
Apply the rhombic antenna result as an initial target, then validate it in the intended installation. Keep the physical layout and feed arrangement consistent while testing, change one parameter at a time, and record the measured outcome before making another adjustment.
