Antenna Dimensions Calculator

I have been making antennas for a while now and I have realised that I have gotten into the bad habit of actually doing the same calculation to get the dimensions over and over again. Obviously I should know better by now. Anyway I decided to write up the calculations very quickly and then to make a quick animation of the results.

Animations created using p5.js

To do list

General

  • [ ] Add toggle to hide or show dimensions

  • [ ] Add current frequency indicator in top left corner of diagram

  • [ ] Create schematic export to pdf or some other format

  • [ ] Add inverse calculation, ie antenna frequency from dimensions

  • [ ] Add reflection from transmission line calculation

Bi-Quad

  • [ ] Add animation

  • [ ] Add Impedance and Gain

Dipole

  • [x] Add dimensions to drawing

Folded Dipole

  • [ ] Add Gain

Helical

  • [ ] Figure out why the first and last vertex of the helix are connected

  • [ ] Figure out how to pause animation when active tab is changed

  • [ ] Add HPBW (Half Power Beam Width) or transmission diagram

  • [ ] Draw reflector dish

  • [ ] Update animations to show dimensions of antenna

  • [ ] Create stop animation option that displays static image with dimensions

Turnstile

  • [ ] Add animation

  • [x] Add dimensions to drawing

Yagi-Uda

  • [ ] Just do it (tick)

Dipole 73 Requires Balun 2.1
Folded Dipole 292 2.1
Helical 140 Depends on Turns
Turnstile 36 Approx 3dB < dipole
Yagi-Uda Driven Element Parasitic Elements
