Intrinsic and mutual admittances of the radiating slots for multibeam multifrequency cylindrical antenna

摘要

The method for the determination of the intrinsic and mutual admittances of the radiating slots for the multibeam multifrequency antenna is presented. The antenna represents the circular metal cylinder with transverse slot radiators, having nonlinear properties. The asquired expressions for the admittances are discussed. The simple calculation formulas are received due to the singularities' separation and simplifications of expressions at small and large arguments of the special functions.
