Mode basis method in spherical coordinate system is considered. Compared to the previous works in this field the method is generalized to take into consideration T-modes in conical lines and more general medium inhomogeneity that contains both radial and angular dependencies. A biconical and alike antennas (bow-tie, blade antenna, V-antenna, TEM-horn, etc.) can be rigorously analyzed with the proposed method.
