Abstract
Abstract The present invention relates to an antenna housing of a portable transceiver, more particularly to an antenna housing for a portable transceiver for improving a receiving level and protecting against fracture and damage to an antenna. The present invention provides an antenna housing of a portable transceiver comprising: an antenna cover having a pair of annular rims at its lower part and protecting an antenna; a tip fixed to an upper end of the antenna; a spring inserted between the annular rims; a pair of cover supporters having a guide groove to guide motion of the spring in the longitudinal direction, a number of locking grooves which are formed at a predetermined interval deeper than the guide groove, and a catching jut in an upper part of the cover supporters; and a connector connecting a lower part of the cover supporters and a transceiver.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
198 words
An antenna housing of a portable transceiver, comprising: an antenna having a tip fixed to an end thereof; an antenna cover having an end with a pair of annular rims attached thereto, said antenna cover protecting said antenna; a spring inserted between the annular rims, said spring and said antenna cover being rotatable relative to each other about a longitudinal axis of said antenna cover; a pair of cover supporters connected together to surround said antenna cover and said spring, and each having: a guide groove for guiding a motion of said spring and said antenna cover in a longitudinal direction and preventing rotation of said spring around the longitudinal axis; a plurality of locking grooves formed at predetermined intervals along the guide groove, and having a depth deeper than a depth of the guide groove, the locking grooves releasably locking said spring and said antenna cover in the longitudinal direction; and a catching jut formed at a first end of said cover supporter for engaging one of said annular rims to limit a movement of said antenna cover in the longitudinal direction; and a connector connecting a second end of said cover supporters to the portable transceiver.
Claim 2
Dependent Claim
198 words
An antenna housing of a portable transceiver, comprising: an antenna having a tip fixed to an end thereof; an antenna cover having an end with a pair of annular rims attached thereto, said antenna cover protecting said antenna; a spring inserted between the annular rims, said spring and said antenna cover being rotatable relative to each other about a longitudinal axis of said antenna cover; a pair of cover supporters connected together to surround said antenna cover and said spring, and each having: a guide groove for guiding a motion of said spring and said antenna cover in a longitudinal direction and preventing rotation of said spring around the longitudinal axis; a plurality of locking grooves formed at predetermined intervals along the guide groove, and having a depth deeper than a depth of the guide groove, the locking grooves releasably locking said spring and said antenna cover in the longitudinal direction; and a catching jut formed at a first end of said cover supporter for engaging one of said annular rims to limit a movement of said antenna cover in the longitudinal direction; and a connector connecting a second end of said cover supporters to the portable transceiver.
Claim 3
Dependent Claim
53 words
The antenna housing as defined in claim 1, wherein said spring includes an elastic strip forming a locking protuberance, said elastic strip being movable along a respective guide groove so that said locking protuberance snaps into a respective locking groove for releasably locking said spring and said antenna cover in the longitudinal direction.
Claim 4
Dependent Claim

Claim 6
Dependent Claim
17 words
The antenna housing as defined in claim 4, wherein said loading coil is fixed to said connector.
Claim 7
Dependent Claim
22 words
The antenna housing as defined in claim 4, further comprising a shielding pipe fixed to said connector and surrounding said loading coil.
Claim 8
Dependent Claim
18 words
The antenna housing as defined in claim 6, wherein said shielding pipe is comprised of a conducting material.
Claim 9
Dependent Claim
25 words
The antenna housing as defined in claim 1, further comprising a shielding pipe fixed to said connector and surrounding a lower portion of said antenna.
Claim 10
Dependent Claim
