Abstract

Embodiments include a communication device, having a wireless communication processor. The communication device includes an antenna connected to a feeding point of the wireless communication processor. The communication device also includes a metal component disposed proximal the antenna and a circuit board including a ground plane. The communication device further includes a first conductive line and a second conductive line which connect the ground plane to two locations on the antenna, on one end and the other end of a location proximal the metal component.

First claim

an antenna element connected to a feeding point; a first conductive line connecting a first point of the antenna element to ground; and a second conductive line connecting a second point of the antenna element to ground, wherein a distance between the first point and the second point of the antenna element is greater than a width of a metal component of a connection port.

2 . The antenna configuration according to claim 1 , wherein the connection port is a universal serial bus (USB) port.

3 . The antenna configuration according to claim 1 , wherein the connection port is an earphone jack.

4 . The antenna configuration according to claim 1 , wherein the connection port is a high definition multimedia interface (HDMI) port.

5 . The antenna configuration according to claim 1 , wherein the first conductive line and the second conductive line each have a coil connected thereto.

6 . The antenna configuration according to claim 1 , wherein the first conductive line and the second conductive line each have a capacitor connected thereto.

7 . The antenna configuration according to claim 1 , wherein the first conductive line and the second conductive line each have a coil and a capacitor connected thereto in a series circuit where the coil and the capacitor are configured to be selectively activated via a switch.

8 . The antenna configuration according to claim 1 , wherein the first conductive line and the second conductive line each have a high-pass filter connected thereto.

9 . The antenna configuration according to claim 1 , wherein the first conductive line and the second conductive line each have a series circuit connected thereto, wherein the series circuit is comprised of a high-pass filter and a coil or a capacitor.

10 . The antenna configuration according to claim 1 , wherein the feeding point is disposed at a position farthest from the points of the antenna element where the first and second conductive lines are connected.

11 . The antenna configuration according to claim 1 , further comprising:
a third conductive line connecting a third point of the antenna element to ground.

12 . The antenna configuration according to claim 1 , wherein the antenna element is configured as a BLUETOOTH connection.

13 . The antenna configuration according to claim 1 , wherein the antenna element is configured as a wireless local area network (WLAN) connection.

14 . The antenna configuration according to claim 1 , wherein the antenna element is configured as a global navigation satellite system (GNSS) connection.

15 . The antenna configuration according to claim 1 , wherein the first conductive line and the second conductive line each have a coil and a capacitor connected thereto in a series circuit where the coil and the capacitor are configured to be selectively activated via a switch, and
wherein the switch further is connected to a high-pass filter.

16 . The antenna configuration according to claim 1 , further comprising:
a second antenna element connected to a second feeding point; a third conductive line connecting a first point on the second antenna element to ground; and a fourth conductive line connecting a second point on the second antenna element to ground, wherein a distance between the first point and the second point of the second antenna element is greater than a width of a second metal component of a second connection port.
