COPLANAR ANTENNA

摘要

A coplanar antenna including a conductive plane, wherein the length of the conductive plane along a first dimension is less than one-quarter of a wavelength of a resonant frequency; an insulating region within the conductive plane, wherein the insulating region is of a shape that outlines a conductive peninsula, wherein: the conductive peninsula is coupled to the conductive plane, the conductive peninsula is substantially coplanar to a major portion of the conductive plane, the conductive peninsula is operable to be electrically coupled to an electric feed circuit, and the conductive peninsula is operable to electrically couple a tunable inductance to the conductive plane after receiving a current from the electric feed circuit.

1. A coplanar antenna comprising:
a single conductive plane having a first dimension and a second dimension, wherein the length of the single conductive plane along the first dimension is the radiating element length of the coplanar antenna and is less than one-quarter of a wavelength of a resonant frequency; an insulating region disposed within the single conductive plane, wherein the insulating region is of a shape that outlines a conductive peninsula, wherein:
the conductive peninsula is coupled to the single conductive plane;the conductive peninsula is substantially coplanar to a major portion of the single conductive plane;the conductive peninsula is operable to be electrically coupled to an electric feed circuit; andthe conductive peninsula is operable to electrically couple a tunable inductance to the single conductive plane after receiving a current from the electric feed circuit: and a first electrical connection that electrically couples the conductive plane to the electric feed circuit and a second electrical connection that electrically couples the conductive peninsula to the electric feed circuit, wherein the first electrical connection is positioned at a point along the first dimension distal from the second electrical connection.
