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 direct or inductive coupling between the chip and antenna. The cap has a protective portion which extends through the cover opening substantially all the way to the substrate so as to prevent accidental contact between the chip, on one hand, and the substrate and/or antenna on tee other.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
150 words
A transponder tag, comprising in combination: (a) a substrate for carrying transponder components and being formed to a predetermined size and configuration and with at least a first surface; (b) a transponder antenna for receiving and transmitting signals and disposed on said first surface of said substrate; (c) a cover arranged over said first surface and covering said antenna and having at least one opening extending therethrough; (d) a cap having a ridge thereon for covering said cover opening and having a protective portion which extends through said cover opening substantially all the way to said substrate; and (e) signal processing chip carried under said cap and arranged in said cover opening within said protective portion of said cap and coupled to said antenna means, whereby said protective portion of said cap prevents accidental contact between said chip on one hand and said substrate and said antenna on the other.
Claim 2
Dependent Claim
150 words
A transponder tag, comprising in combination: (a) a substrate for carrying transponder components and being formed to a predetermined size and configuration and with at least a first surface; (b) a transponder antenna for receiving and transmitting signals and disposed on said first surface of said substrate; (c) a cover arranged over said first surface and covering said antenna and having at least one opening extending therethrough; (d) a cap having a ridge thereon for covering said cover opening and having a protective portion which extends through said cover opening substantially all the way to said substrate; and (e) signal processing chip carried under said cap and arranged in said cover opening within said protective portion of said cap and coupled to said antenna means, whereby said protective portion of said cap prevents accidental contact between said chip on one hand and said substrate and said antenna on the other.
Claim 3
Dependent Claim
29 words
The transponder tag of claim 1, wherein said chip is carried by said cap so as to be spaced from said antenna but still inductively coupled to said antenna.
Claim 4
Dependent Claim
18 words
The transponder tag of claim 1, wherein said substrate and said antenna are made of flexible sheet material.
Claim 5
Dependent Claim
15 words
The transponder tag of claim 3, wherein said cover is made of flexible sheet material.
