Document Type and Number:
Japanese Patent JP3648314
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain the compact antenna receiving a BS broadcast and a broadcast at an UHF band.
SOLUTION: Slits 3-1 to 3-6 are formed to a conductor face formed to be a parabolic face to separates the conductor face.
