Abstract :
A mathematical model of the radiation from an open-ended circular waveguide excited by the symmetrical modes TM01 and TE01 has been developed. Easy to use and reliable approximation expressions, which allow calculation of the power radiation pattern both for TM01 and TE01 waveguide excitation on the whole observation space, have been obtained. The mathematical model is based on the accurate solution developed by Weinstein. It has been shown that the approximation absolute error does not exceed 0.6 dB and 1.5 dB till the level -30 dB for TM01 and TE01 modes respectively
