Abstract
An antenna system, in one example implementation, can include antenna portions including a first portion of the antenna to receive a radio frequency (RF) signal. The antenna can include a second portion capacitively coupled to the first portion, wherein the capacitive coupling of the second portion to the first portion increases the high-band resonances. The antenna can include a third portion of the antenna connected to a connector. The third portion can be capacitively coupled to the first portion to excite wide low-band resonances and high-band resonances. The connector can be a ground for the third portion.
Claims14
An antenna system, comprising:
- a first antenna portion of the antenna to receive a radio frequency (RF) signal, the first antenna portion comprising:
- a first portion extending from a feed a first distance along a first surface of a device;
- a second portion extending perpendicular to the first portion along a second surface of the device, wherein the second portion curves back and extends a third distance along the first surface;
- a second antenna portion of the antenna capacitively coupled to the first antenna portion, wherein the capacitive coupling of the second portion to the first portion increases the high-band resonances;
- a third antenna portion, that is a continuation of the second antenna portion, of the antenna connected to a connector, wherein:
- the third antenna portion is capacitively coupled to the first antenna portion to excite wide low-band resonances and high-band resonances;
- and
- the connector is a Universal Serial Bus (USB) port that is a ground for the third antenna portion.
A computing device, comprising:
- an antenna, wherein the antenna comprises:
- a feeding arm to receive a radio frequency (RF) signal, the feeding arm comprising:
- a first portion of the feeding arm extending from a feed a first distance along a first surface of the computing device;
- a second portion of the feeding arm extending perpendicular to the first portion along a second surface of the computing device, wherein the second portion curves back and extends a third distance along the first surface;
- a parasitic arm, wherein a first portion of the parasitic arm is proximal to the feeding arm and a second portion of the parasitic arm is proximal to a coupled arm;
- a coupled arm, that is a continuation of the parasitic arm, connected to a connector that is a Universal Serial Bus (USB) port such that the connector grounds the coupled arm, wherein:
- a first portion of the coupled arm grounded to the connector is proximal to the feeding arm;
- a second portion of the coupled arm travels over a side portion of the connector;
- and
- a third portion of the coupled arm distal to the feeding arm.
A method, comprising:
- positioning a feeding arm of an antenna that receives a radio frequency (RF) signal proximal to a parasitic arm of the antenna, the feeding arm comprising:
- a first portion of the feeding arm extending from a feed a first distance along a first surface of a device;
- a second portion of the feeding arm extending perpendicular to the first portion along a second surface of the device, wherein the second portion curves back and extends a third distance along the first surface;
- loading the parasitic arm of the antenna with a reactive component;
- adjusting an electrical length of the parasitic arm;
- and
- tuning a lowband frequency of parasitic arm without affecting a highband frequency based on the electrical length, wherein the parasitic arm is proximal to a coupled arm;
- and
- connecting the coupled arm to a connector that is a Universal Serial Bus (USB) port such that the connector grounds the coupled arm.
