Abstract
Abstract The invention is related to a telescopic and flexible antenna, comprising a plurality of main bodies each being a hollow tube to the lower end of which a conductor plug is affixed, with two arched conductor plates embracing the peripheral surface thereof to form a telescopic antenna, and characterized in that each main body encloses a resilient metal plate with conductor rings at its ends and abutting against the arched conductor plates of another main body.

Claim 1
Independent Claim
236 words
A telescopic and flexible antenna, comprising a plurality of main bodies telescopically joined together, each of said plurality of main bodies being formed by (1) a longitudinally extended tubular member having a through bore and being formed of a plastic material composition, said tubular member having a longitudinally extended recess formed in open communication with said through bore, (2) a resilient conductive plate member disposed within said longitudinally extended recess, said conductive plate member having a pair of ring shaped portions respectively formed on opposing ends thereof, each of said ring shaped portions being disposed within a respective annular recess formed at opposing ends of said longitudinally extended recess, (3) a conductive plug member having a first end portion extending into said through bore and contacting a respective one of said pair of ring shaped portions of said conductive plate member and a second end portion extending from an end of said tubular member, and (4) a pair of arched conductive plates coupled to said second end portion of said plug member and extending circumferentially about a perimeter surface thereof, said second end portion of said plug member of a first of said plurality of main bodies extending into said through bore of a second of said plurality of main bodies and at least one of said pair of arched conductive plates of said first main body contacting said plate member of said second main body.
Claim 2
Dependent Claim
236 words
A telescopic and flexible antenna, comprising a plurality of main bodies telescopically joined together, each of said plurality of main bodies being formed by (1) a longitudinally extended tubular member having a through bore and being formed of a plastic material composition, said tubular member having a longitudinally extended recess formed in open communication with said through bore, (2) a resilient conductive plate member disposed within said longitudinally extended recess, said conductive plate member having a pair of ring shaped portions respectively formed on opposing ends thereof, each of said ring shaped portions being disposed within a respective annular recess formed at opposing ends of said longitudinally extended recess, (3) a conductive plug member having a first end portion extending into said through bore and contacting a respective one of said pair of ring shaped portions of said conductive plate member and a second end portion extending from an end of said tubular member, and (4) a pair of arched conductive plates coupled to said second end portion of said plug member and extending circumferentially about a perimeter surface thereof, said second end portion of said plug member of a first of said plurality of main bodies extending into said through bore of a second of said plurality of main bodies and at least one of said pair of arched conductive plates of said first main body contacting said plate member of said second main body.
