Patent ID: 8102327

Claim:
An antenna system, comprising: a printed circuit board comprising a first dielectric layer and a second dielectric layer; a conductive ground plane bounded by respective portions of the first and second dielectric layers of the printed circuit board; a balanced folded dipole, wherein a first portion of the folded dipole is located on the first dielectric layer, and a second portion of the folded dipole is located on the second dielectric layer; first and second transmission lines coupled to respective folded dipole portions; and a balanced matching network comprising first and second portions, the first and second matching network portions coupled to respective transmission lines and having substantially equal electrical impedances, each portion comprising: a tapered first microstrip, comprising a narrow end electrically coupled to a respective transmission line; a second microstrip electrically coupled to the first microstrip; and a third microstrip coupled substantially orthogonally to the second microstrip via a mitered bend.
