An offset overlapping slot line comprises a first metallization on a first side of a dielectric substrate and a second metallization on a second side of a dielectric substrate cooperating to yield a transmission line. By overlapping the first and second metallizations, one may achieve much lower impedance than in traditional slot line transmission line structures. An offset overlapping slot line antenna apparatus incorporates an offset overlapping slot line in a feed region. This has the benefit of yielding a low input impedance. A low input impedance allows a transmit antenna to bed driven efficiently even by low voltage, high current drivers. Also a low input impedance can help reduce thermal noise in a received front-end. This technique is well suited for application to dipole, monopole, slot, and annular slot antennas, to name a few examples.
