Abstract

A circuit board for an antenna assembly comprising: an antenna, a slot extending from a front end of the circuit board for trapping ground currents generated by the antenna, at least one electronic component placed at a front end of the circuit board, at least one of a biasing line and a ground line for the at least one electronic component wherein the biasing line and/or the ground line are routed from the electronic component through the slot.

Claims

1. A circuit board for an antenna assembly comprising:

an antenna,

a slot extending along a path from a front end of the circuit board, for trapping ground currents generated by the antenna,

at least one electronic component placed at a front end of the circuit board; and

a biasing line and a ground line for the at least one electronic component, wherein the biasing line and the ground line are routed from the electronic component from the front end of the circuit board through the slot, along the path of the slot.

2. The circuit board according to claim 1, wherein the slot has a length corresponding to the quarter wavelength of operating frequency band of the antenna.

3. The circuit board according to claim 1, wherein the slot is terminated at one end by a short circuit and, and the ground line is connected to the said end.

4. The circuit board according to claim 3, wherein a filtering circuit is provided at the short circuit end of the slot.

5. The circuit board according to claim 1, wherein the at least one electronic component comprises at least one of a display, an LED, an infra-red sensor, a control unit, and a USB connector.

6. An electronic communication device comprising the circuit board according to claim 1.

7. The electronic communication device according to claim 6 wherein the electronic communication device is a gateway device or a set top box.
