Abstract

An embodiment of the present invention provides a phase shifter, comprising a substrate, resistive ink adjacent one surface of said substrate and separating a voltage tunable dielectric material from said surface of said substrate and a plurality of conductors adjacent said voltage tunable dielectric material separated so as to form a gap filled with resistive ink in said gap.

Claims (10)

1. A phase shifter, comprising:

a substrate;

resistive ink adjacent one surface of said substrate and separating a voltage tunable dielectric material from said surface of said substrate; and

a plurality of conductors adjacent said voltage tunable dielectric material separated so as to provide a gap filled with said resistive ink in said gap.

2. The phase shifter of claim 1 , further comprising a voltage source connected to at least one of said plurality of conductors and connected to said resistive ink separating said substrate and said voltage tunable dielectric material.

3. A method of manufacturing a phase shifter, comprising:

providing a substrate;

placing resistive ink adjacent one surface of said substrate and between a voltage tunable dielectric material and said substrate; and

placing a plurality of conductors adjacent said voltage tunable dielectric material separated so as to provide a gap filled with said resistive ink.

4. The method of claim 3 , further comprising connecting a voltage source to at least one of said plurality of conductors and to said resistive ink separating said substrate and said voltage unable dielectric material.
