Abstract
A effectively balanced dipole antenna is provided comprising an unbalanced microstrip antenna having a transmission line interface and a planar balun connected to the transmission line interface of the antenna. The balun can be coplanar or multi-planar. For example, a coplanar balun includes an unbalanced coplanar transmission line, with a signal line interposed between a pair of coplanar grounds, and a pair of planar stubs plan-wise adjacent the coplanar grounds. The coplanar grounds are connected to the plane stubs with conductive lines proximate to the antenna transmission line interface. A microstrip planar balun includes an unbalanced microstrip signal line, a microstrip ground formed on the dielectric layer underlying the signal line, and a pair of planar stubs, plan-wise adjacent the microstrip ground. The planar stubs can be located on the same dielectric layer as the signal line or the ground. A stripline planar balun is also provided.
