Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
50 words
A chip antenna characterized by comprising: an antenna conductor (10); and a dielectric chip (12) which stacks on a portion
of said antenna conductor, wherein a conductor exposed portion of said
antenna conductor which is not overlapped on the
dielectric chip is bent along the surface of the
dielectric chip.
Claim 2
Dependent Claim
22 words
The chip antenna according to claim 1, characterized in that said antenna conductor is a
meandered conductor formed in a meandered shape.
Claim 3
Dependent Claim
31 words
The chip antenna according to claim 2, characterized in that said dielectric chip is formed
such that said meandered conductor is overlapped to a
middle portion of a meander width direction.
Claim 4
Dependent Claim
31 words
The chip antenna according to claim 2, characterized in that said dielectric chip is formed
such that said meandered conductor is overlapped to a
middle portion of a meander width direction.
Claim 5
Dependent Claim
51 words
The chip antenna according to claim 1, characterized in that said dielectric chip comprises
a plurality of dielectric chips arranged apart from one
another in a meander width direction of said meandered
conductor, said conductor exposed portion of said
meandered conductor is bent, and said plurality of
dielectric chips are stacked.
Claim 6
Dependent Claim
51 words
The chip antenna according to claim 1, characterized in that said dielectric chip comprises
a plurality of dielectric chips arranged apart from one
another in a meander pitch direction of said meandered
conductor, said conductor exposed portion of said
meandered conductor is bent, and said plurality of
dielectric chips are stacked.
Claim 7
Dependent Claim
27 words
The chip antenna according to claim 6, further
comprising an extension prevention member (28)
configured to prevent the meandered conductor from
extending in a meander pitch direction.
Claim 8
Dependent Claim
35 words
The chip antenna according to any one of
claims 1 to 7, characterized in that a trench in which
the bent conductor is to be disposed is formed in the
surface of the dielectric chip.
Claim 9
Dependent Claim
28 words
The chip antenna according to any one of
claims 1 to 8, characterized in that an overlapped
portion of said antenna conductor is buried in said
dielectric chip.
Claim 10
Dependent Claim
26 words
The chip antenna according to any one of
claims 1 to 8, characterized by further comprising
a protection film (24) to cover said conductor exposed
portion.
Claim 11
Dependent Claim
34 words
The chip antenna according to claim 10, characterized in that said protection film is formed of
a resin material having a viscosity during molding
which is lower than the viscosity of said dielectric
chip.
Claim 12
Dependent Claim
49 words
A manufacturing method of a chip antenna characterized by comprising: forming a conductor pattern having a meandered
conductor; and forming a dielectric chip so as to overlap at
least a portion of said meandered conductor in a
meander width direction or a meander pitch direction in
the dielectric chip.
Claim 13
Dependent Claim
68 words
The manufacturing method according to
claim 12, characterized in that said conductor pattern has a pattern in which
the meandered conductor and a frame to surround the
meandered conductor are integrally formed, and after forming the dielectric chip, the meandered
conductor is separated from the frame and a portion
excluding a portion which is buried in the dielectric
chip is bent along a surface of the dielectric chip.
