    摘要: The problem of recurrent solder joint failure in spiral antennas is solved by the present invention through the use of resistive/capacitive contacts. Specifically, an electrical connector is provided for connecting opposed conductors disposed on a stripline, to a spiral antenna having a pair of dipole conductors disposed on a substrate. The connector includes a housing having a base, and a sidewall for supporting the substrate. A center post having first and second ends, and a cylindrical aperture, is mounted in the housing. The substrate is secured to the first end of the center post, the second end thereof secured to the base of the housing. A stripline contact snubber is supported in an end of the cylindrical aperture adjacent the substrate and receives the stripline. To ensure RF continuity between the stripline conductors and the dipole conductors, one or more mechanically compliant, leaf spring resistive/capacitive contacts are provided. Each of the resistive/capacitive contacts preferably includes a first portion soldered to an opposed conductor of the stripline, and a second portion extending from the first portion. Alternatively, each contact may be an integral extension of one of the stripline conductors. The second portion of each resistive/capacitive contact is compressed between the contact snubber and one of the dipole conductors, and thus placed in abutting relation therewith. Preferably, each resistive/capacitive contact is formed of a flexible metal material, or a metal-plated plastic material.
