Abstract: A method for coupling a coaxial transmission line with a micro-strip package transition is disclosed. The method includes offsetting a conductor from a center, of the coaxial transmission line. The offsetting the conductor concentrates a first electromagnetic field lines of the coaxial transmission line towards a single ground plane. Further, the method includes coupling the micro-strip along a length of the offset conductor, using a connector. The first electromagnetic field lines of the offset conductor flows into the micro-strip to transmit energy packets with least discontinuity, for smooth transition of energy packets, with less or minimal signal to noise ratio.
