
Above the antenna, the antenna surface is parallel to the antenna surface
The height of the antenna to the inner surface of the radome H
 The ideal height is an integer multiple of the half-wavelength of electromagnetic
waves in the air
 ,where m is a positive integer, co is the vacuum speed of light, f is the
working center frequency.

For example,24.125GHz center frequency,its half-wavelenath in the air is about
6.2mm
The thickness of the antenna cover D

The ideal thickness is an integer multiple of the half-wavelengthof the
electromagnetic wave in the medium
 ,where m is a positive integer,  is the relative dielectric constant
of the radome material

For example, an ABS material  = 2.5, its half wavelength of about 3.92mm
