US 2013/0154884 A1 · BROADBAND PLANAR INVERTED-F ANTENNA

Abstract

A broadband planar inverted-F antenna includes a first radiation conductor, a second radiation conductor and a third radiation conductor. The first radiation conductor includes a first inclined-plane portion and a feeding point. The feeding point is located at one end of the first inclined-plane portion. The second radiation conductor is connected to the first radiation conductor at the feeding point. The third radiation conductor is connected to the first radiation conductor, and includes a second inclined-plane portion and a ground point. The second inclined-plane portion is separated from and facing to the first inclined-plane portion. The ground point is located at one end of the second inclined-plane portion and facing to the feeding point, wherein the distance between the first inclined-plane portion and the second inclined-plane portion is gradually increased from the part near the feeding point along a direction departing from the feeding point.

Dependent claims

A broadband planar inverted-F antenna (PIFA), comprising:

a first radiation conductor, comprising:
a first inclined-plane portion;
and
a feeding point located at one end of the first inclined-plane portion;
a second radiation conductor connected to the first radiation conductor at the feeding point ;
and
a third radiation conductor connected to the first radiation conductor, the third radiation conductor comprises:
a second inclined-plane portion separated from and facing to the first inclined-plane portion;
and
a ground point located at one end of the second inclined-plane portion and facing to the feeding point, wherein the distance between the first inclined-plane portion and the second inclined-plane portion is gradually increased from the part near the feeding point along a direction departing from the feeding point.

7 more elements

A broadband planar inverted-F antenna, comprising:

a first radiation conductor, comprising:
an indented structure, wherein the distance between two opposite sides of the indented structure is gradually increased from an opening of the indented structure towards the indented structure;
a feeding point located at the opening of an opening of the indented structure for receiving a radio frequency signal;
and
a ground point located at the opening of an opening of the indented structure and facing to the feeding point, wherein after the radio frequency signal is fed to the antenna via the feeding point, a first travelling wave radiation is generated by the indented structure;
and
a second radiation conductor connected to the first radiation conductor at the feeding point, wherein after the radio frequency signal is fed via the feeding point, a resonance standing wave radiation is generated by the second radiation conductor.
