Antenna unit having a wide band
First Claim
1. An antenna unit comprising:
- an upper dielectric;
a lower dielectric; and
a conductive pattern sandwiched between said upper dielectric and said lower dielectric, said conductive pattern having a feeding point at a substantially center portion of a front thereof, said conductive pattern comprising a reversed triangular portion having a right-hand taper part and a left-side taper part which widen from the feeding point at a predetermined angle toward a right-hand side and a left-hand side, respectively, and a rectangular portion having a base side being in contact with an upper side of said reversed triangular portion.

Abstract
A UWB antenna has an upper dielectric, a lower dielectric, and a conductive pattern sandwiched therebetween. The conductive pattern has a feeding point at a substantially center portion of a front surface. The conductive pattern has a reversed triangular portion having a right-hand taper part and a left-side taper part which widen from the feeding point at a predetermined angle toward a right-hand side surface and a left-hand side surface, respectively, and a rectangular portion having a base side being in contact with an upper side of the reversed triangular portion. The rectangular portion may preferable have at least one slit formed therein.
