Low-profile loop-shaped inverted-F wire antenna with dualmode operation

Abstract

This paper proposes a new design of a dualmode operation antenna. We introduced loop-shaped inverted-F wire antenna using a parasitic element within a feeding element for additional resonance mode that has small and low profiled structure. This paper discusses theoretical dual resonance operation and investigates the characteristics along some dimensional parameters by numerical analyses. The measurement results with the proposed structure will be also presented.
