Abstract
A monitor tag (30) having a radio frequency transmitter (32) and a patch antenna (10). The antenna is in communication with the transmitter and has a first conductive patch (12) and a second conductive patch (16) substantially parallel to each other, and separated from each other by a dielectric material (18) in contact with both patches and having a thickness sufficient to create a gap between the patches wherein the radiation resistance will be controlled during operation of the antenna. The first conductive patch has a dimension of one-quarter or one-half wavelength, depending upon available space and desired pattern. Because the electric field is launched from the gap between the patches and is highly concentrated, bringing the monitor tag close to a metal object or attaching it thereto will have minimal impact on the impedance of the antenna.

STATEMENT UNDER ARTICLE 19
Through the attached amendment, Applicants specifically recite the presence of a housing within which the transmitter and antenna of the monitor tag/monitor tag device are situated. The preamble of every claim recites the word "tag" which, by definition, can be identified as a substrate which, of course, can function as a housing, and is particularly exemplified as a "housing." Claim 17 is amended to recite the fastener member as exemplified in Figure 6. Finally, the typographical error "0.30" in each of Claims 4, 7, 12, 15, and 20 is amended to read --0.030--.
Claims 2 and 3 depend upon independent Claim 1, while Claims 9 and 10 depend upon independent Claim 9. Both Desantis et al . and James et al . are cited as showing copper patches in Ogawa et al . as being obvious. However, modifying the antenna construction of Ogawa et al . still does not teach, suggest, or make obvious the instantly claimed association of such an antenna with a transmitter wherein both the antenna and the transmitter are within a housing which is attachable to an object as instantly claimed.
Claims 4 and 5 depend upon independent Claim 1, while Claims 12 and 13 depend upon independent Claim 9. Gunnarsson is cited for disclosing an antenna in which a dielectric constant of around 4 is used, further finding that selection of an appropriate constant and thickness for dielectric material would result from routine experimentation. However, and irrespective of dielectric constant, thickness, etc. as taught by Gunnarsson, Ogawa et al . in view of DeSantis et al . or James et al . and further in view of Gunnarsson do not teach, suggest, or make obvious the instantly claimed association of such an antenna with a transmitter wherein both the antenna and the transmitter are within a housing which is attachable to an object as instantly claimed.
Claim 17 (as well as dependent Claims 22 and 24) recite a monitor tag device to be worn by a person. Larsen is cited for teaching the association of a transmitter with a garment (a vest) to be worn by a heart patient to thereby transmit heart and related activity data to a monitor. Gunnarsson, earlier discussed, is cited for teaching attachment to clothing with a clip 23. Applicant's do not claim "wearing" a monitor tag device, but rather claim a monitor tag device having a housing with a fastener member that is releasably attachable to a person to thereby monitor the whereabouts of said person.
Both Claims 18 and 19 are dependant claims depending either directly (Claim 18) or indirectly (Claim 19) on independent Claim 17.
Claims 20, 21, and 23 depend directly or indirectly upon independent Claim 17.
