16. An antenna structure included in a utility meter, comprising:
-
a planar dielectric; a conductor layout formed on a first side of the planar dielectric, wherein the conductor layout forms a first folded dipole connected in parallel to a second folded dipole, and wherein the first folded dipole has a first central region and the second folded dipole has a second central region, the conductor layout further comprising; a first pair of tuning stubs extending into the first central region of the first folded dipole, and a second pair of tuning stubs extending into the second central region of the second folded dipole; a feed line conductor formed on a second side of the planar dielectric, opposite to the first side; and an impedance matching conductor formed on the second side of the planar dielectric. - View Dependent Claims (17, 18, 19, 20)
