A pseudo-coaxial vertical transition ( 10 ) includes a substrate ( 16 ). A bump array is disposed in a substantially concentric bump pattern upon the substrate ( 16 ) for simulating a pseudo-coaxial vertical electromagnetic wave propagation. The bump array is formed from a centrally disposed bump ( 32 ) having a predetermined bump diameter, and a plurality of at least five ground bumps ( 36 ) substantially equi-distant and circularly disposed about the centrally disposed bump ( 32 ). The predetermined bump diameter and a bump spacing of the centrally disposed bump are determined in relation to the plurality of ground bumps and a dielectric constant of air for providing a characteristic impedance.
