First Claim
Patent Images
1. A planar antenna comprising:
- a driver having a folded dipole;
coplanar strips coupled with the driver;
an integral balun coupled with the coplanar strips;
a substrate, with a first side and a second side opposite to the first side, having a dielectric constant of at least 10, the first side coupled with the driver, the coplanar strips, and the integral balun;
a truncated ground plane coupled with the second side of the substrate, the truncated ground plane having a continuous serrated edge for reflecting waves; and
a feeding structure having a coplanar waveguide (CPW), on the first side of the substrate, coupled with the integral balun to feed the integral balun.
