Abstract:
1. An antenna circuit which comprises a substrate and a planar circuit comprising a circuit line of a conductive material extending laterally on a surface of the substrate and at least one conductive pad also extending laterally on the surface of the substrate and electrically connected with the circuit line of the planar circuit at at least one electrical connection point, wherein cutting lines are provided in the substrate laterally beyond and around an outer periphery of the conductive pad, wherein the cutting lines extend laterally into the conductive pad from the outer periphery of the conductive pad such that the cutting lines bracket the at least one connection point without traversing either the circuit lines or the connection point, and the cutting lines approach each other in the conductive pad while maintaining electrical connection within the pad, and wherein the cutting lines extending into the conductive pad form straight lines which approach each other and define a section angle of greater than 10 degrees and less than 120 degrees.
