Title:
ANTENNA FOR PORTABLE RADIO EQUIPMENT
Document Type and Number:
Japanese Patent JP3635544
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve a gain and to stabilize antenna characteristic.
SOLUTION: Strip antenna elements 3a-3d consisting of conductors are arranged in band parts 2a, 2b, respectively. The antenna elements 3a, 3d are connected with each other in the inside of a main body part 1. The antenna elements 3b, 3c are connected to a radio circuit part 6. Also, the outer ends of the antenna elements 3a, 3b are connected to loop connection parts 11a. 11b whose ' ends are exposed advancing the inside of the band part 2a in a buckle part 4. While, a part of the antenna elements 3c, 3d is exposed outward from the band part 2b. When the band parts 2a, 2b are fixed with the buckle part 4, the loop connection parts 11a, 11b are directly connected electrically to the exposed parts of the antenna elements 3c, 3d by the pressing power of the band parts, which forms a loop antenna of two turns.
