Abstract
Balanced microstrip folded dipole antennas and matching networks are disclosed. In some examples, an antenna system includes a printed circuit board having first and second dielectric layers, and respective portions of the first and second dielectric layers bound a ground plane. The system further includes a balanced folded dipole, wherein a first portion of the folded dipole is located on the first dielectric layer, and a second portion is located on the second dielectric layer. First and second transmission lines are coupled to respective folded dipole portions. A matching network includes first and second portions that are coupled to respective transmission lines and have equal impedances. Each matching network portion includes a tapered first microstrip, having a narrow end coupled to a respective transmission line, a second microstrip coupled to the first microstrip, and a third microstrip coupled orthogonally to the second microstrip via a mitered bend.
