Abstract

Abstract A base plate (11) supports a non-conductive substrate (24) on which a conductive substrate (25) is mounted. A connector (19) conducts a signal to or from the conductive substrate, Inductive posts (28) such as screws are electrically connected to the conductive substrate and the base at selected locations for inductively tuning the antenna. A radome (26) is supported by the base and covers the conductive and non-conductive substrates so that the antenna may be mounted in a low profile or near-flush configurations. The non-conductive substrate may be teflon glass or air. The conductive substrate may be a copper-clad disc located on the teflon glass.
