An antenna (100) has a connector (200) having a ground lead (102) and a signal lead (114). A dielectric (112) captures and embeds the connector (200) forming a connector substrate assembly (120) having a first side (122) and a second opposite side (124). A first conductive material (104) is affixed to the first side (122) of the connector substrate assembly (120) and coupling to the ground lead (102) and a second conductive material (110) is affixed to the second opposite side (124) of the connector substrate assembly (112) coupling the signal lead (114).

DETAILED DESCRIPTION Thus, what is claimed is: 1.
A method for forming a molded patch antenna having an embedded connector, comprising the steps of: (a) forming a connector by coupling a cylindrical housing terminating in a cylindrical ground lead with a circular signal lead; (b) injecting dielectric insulating the cylindrical ground lead from the circular signal lead forming a connector substrate assembly having first side coupled with the cylindrical ground lead and a second opposite side for coupling with the circular signal lead; (c) removing the connector substrate assembly from the mold; (d) affixing a conductive material to the first side of the connector substrate assembly thereby coupling to the cylindrical ground lead; and (e) affixing another conductive material to the second opposite side of the connector substrate assembly thereby coupling to the circular signal lead.
2.
A method forming a molded patch antenna having a connector being embedded therein, comprising the steps of: (a) coupling a circular signal terminal with a cylindrical ground terminal in the mold; (b) injecting dielectric for capturing and insulating the circular signal terminal centrally positioned within the cylindrical ground terminal of the connector to form a connector substrate assembly; (c) affixing a conductive surface to a first side of the connector substrate assembly thereby coupling to the cylindrical ground terminal of the connector; and (d) affixing second conductive surface to an opposite side of the connector substrate assembly thereby coupling to the circular signal terminal of the connector.
3.
The method according to claim 2 wherein the step (b) of injecting further comprising a step of obtaining a predetermined impedance.
4.
The method according to claim 2 wherein the step (b) of injecting further comprising a step of forming a connector.
5.
An antenna, comprising: a connector having a cylindrical ground lead and a circular signal lead; a dielectric capturing and embedding the circular signal lead centrally located within the cylindrical ground lead of the connector forming a connector substrate assembly having a first side and a second opposite side; a first conductive surface affixed to the first side of the connector substrate assembly being electrically coupled to the cylindrical ground lead; and a second conductive surface affixed to the second opposite side of the connector substrate assembly being electrically coupled to the circular signal lead
