Units?

[edit]

The equations as presented here are clearly showing results in radians (in the table) yet the example plot (which clearly presents the same values) is labelled in units of degrees. This is obviously wrong. Also, this presentation would suggest that all antennas of the same shape have the same lobe pattern. This is clearly false. The information required to correctly predict/model lobe patterns for the antenna shapes mentioned here involves the relationship between the antenna size and the wavelength(s) of light being emitted from the antenna (assuming a source at the focus, etc.)

Thanks for starting the page - but it needs a lot of work. 65.202.227.115 (talk)mjd 14:52, 13 March 2009

• You are always welcome to improve the article
• Not clear why you think that it is wrong to have a sample radiation pattern plot use degrees, and a canonical equation not use degrees. In practice degrees are always used, hence a sample antenna radiation pattern plot should use degrees. The canonical equation should use radians because to add all the factors of 57.3 ${\displaystyle \left(180/\pi \right)}$ would make the equations more cumbersome than needed.
• The article only suggests that all aperture antennas which have a uniform aperture distribution would have the same sidelobe level. I think this is true.

I think it would be nice to have the 'reason' for side lobes better explained... more than refering to Fourier Transform ... e.g. on a physical/electro-magnetic level. — Preceding unsigned comment added by 193.17.11.20 (talk) 09:20, 16 July 2015 (UTC)[reply]
