Abstract
The effect of profile errors with large correlation diameter on the boresight crosspolarisation of axisymmetric antennas is investigated. An expression for boresight isolation as a function of the correlation diameter, the r.m.s. surface error and the polarisation efficiency of the antenna is given. Curves of isolation as a function of the r.m.s. surface error and the correlation diameter are given for polarisation efficiencies of 0·99 and 0·999 (i.e. for antennas with peak off-axis crosspolarisation of −25·3 dB and −35·4 dB, respectively).
