Calculation method for microwave pyramidal horn radiators with curvilinear generatrix

A. A. Karpenko, Ya. I. Lepikh


Calculation method for pyramidal horn radiators (PHR) with curvilinear generatrix has been developed on the basis of the theory of waveguide tapers. This method makes it possible to reduce the value of spurious reflection coefficients and transformation of the principal wave into waves of higher order modes by forming generatrixes of walls with specific curvilinearity.
