Abstract
Abstract A transponder antenna is carried by a substrate and is sandwiched between the substrate and a cover sheet. A rectangular opening extends through the cover sheet and receives a signal processing chip adhesively carried in a recess below a cap which covers the opening. The chip is spaced with respect to the antenna so as to facilitate inductive coupling between the chip and antenna.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
125 words
A transponder tag, comprising in combination: (a) substrate means for carrying transponder components and being formed to a predetermined size and configuration and with at least a first surface; (b) transponder antenna means, having an antenna opening thereon, for receiving and transmitting signals and disposed on said first surface of said substrate means; (c) cover means arranged over said first surface and covering said antenna means and having at least one opening extending therethrough in substantially axial alignment with said antenna opening; (d) cap means having a ridge thereon for covering said cover opening; and (e) signal processing chip means carried under said cap means and arranged in said cover opening so as to be inductively coupled to said antenna means through said antenna opening.
Claim 2
Dependent Claim
125 words
A transponder tag, comprising in combination: (a) substrate means for carrying transponder components and being formed to a predetermined size and configuration and with at least a first surface; (b) transponder antenna means, having an antenna opening thereon, for receiving and transmitting signals and disposed on said first surface of said substrate means; (c) cover means arranged over said first surface and covering said antenna means and having at least one opening extending therethrough in substantially axial alignment with said antenna opening; (d) cap means having a ridge thereon for covering said cover opening; and (e) signal processing chip means carried under said cap means and arranged in said cover opening so as to be inductively coupled to said antenna means through said antenna opening.
Claim 3
Dependent Claim
17 words
The transponder tag of claim 1, wherein said opening through said cover means is substantially rectangular shaped.
Claim 4
Dependent Claim
21 words
The transponder tag of claim 1, wherein said opening through said cover means is substantially centrally disposed in said cover means.
Claim 5
Dependent Claim
22 words
The transponder tag of claim 1, wherein said opening through said cover means is disposed proximate an edge of said cover means.
Claim 6
Dependent Claim
33 words
The transponder tag of claim 1, wherein said chip means is carried by said cap means so as to be spaced from said antenna means but still inductively coupled to said antenna means.
Claim 7
Dependent Claim
24 words
The transponder tag of claim 5, wherein said cap means is formed with a recess and said chip means is lodged in said recess.
Claim 8
Dependent Claim
17 words
The transponder tag of claim 6, wherein said chip means is of greater thickness said cover means.
Claim 9
Dependent Claim
111 words
A transponder tag, comprising: (a) a substrate formed to a predetermined size and configuration and with at least a first surface; (b) a transponder antenna carried by said first surface of said substrate and having an antenna opening thereon; (c) a cover of a size and configuration corresponding to said substrate and including at least an opening extending through said cover in substantially axial alignment with said antenna opening; (d) a cap having a ridge thereon for covering said cover opening; (e) a signal processing chip carried under said cap and arranged in said cover opening, so that said chip is being inductively coupled to said antenna through said antenna opening.
Claim 10
Dependent Claim
111 words
A transponder tag, comprising: (a) a substrate formed to a predetermined size and configuration and with at least a first surface; (b) a transponder antenna carried by said first surface of said substrate and having an antenna opening thereon; (c) a cover of a size and configuration corresponding to said substrate and including at least an opening extending through said cover in substantially axial alignment with said antenna opening; (d) a cap having a ridge thereon for covering said cover opening; (e) a signal processing chip carried under said cap and arranged in said cover opening, so that said chip is being inductively coupled to said antenna through said antenna opening.
Claim 11
Dependent Claim
16 words

Claim 12
Dependent Claim
16 words
The transponder tag of claim 8, wherein said opening through said cover is substantially rectangular shaped.
Claim 13
Dependent Claim
19 words
The transponder tag of claim 8, wherein said opening through said cover is substantially centrally disposed in said cover.
Claim 14
Dependent Claim
20 words
The transponder tag of claim 8, wherein said opening through said cover is disposed proximate an edge of said cover.
Claim 15
Dependent Claim
29 words
The transponder tag of claim 8, wherein said chip is carried by said cap so as to be spaced from said antenna but still inductively coupled to said antenna.
Claim 16
Dependent Claim
22 words
The transponder tag of claim 13, wherein said cap is formed with a recess and said chip is lodged in said recess.
