Abstract :
The r.f. surface reflectivity of a parabolic antenna reflector fabricated from carbon fibre reinforced plastic with high modulus fibres, has been investigated at L- and S-band frequencies by a swept frequency gain comparison method. The gain of the antenna with the reflector uncoated was compared with that of the same unit but with a metal coating on the reflector.
