A miniaturized planar microstrip balun includes first and second microstrip coupling segments that are considerably shorter than a quarter of a guide wavelength (λg/4 ). In at least one embodiment, a microstrip balun is provided that does not require the use of lumped circuit elements or short circuit terminations.
