Abstract

Embodiments include a wireless microphone comprising an elongated main body configured for handheld operation of the microphone; a display bezel area included in the main body; a first antenna positioned at a bottom end of the main body; and a second antenna integrated into the display bezel area. Embodiments also include a wireless handheld microphone comprising a main body having a conductive housing and a tubular shape configured for handheld operation of the microphone; an opening included on a side surface of the conductive housing; a non-conductive cover coupled to the conductive housing and configured to cover the opening; and an antenna positioned adjacent to the non-conductive cover.

First claim

The invention claimed is:

1. A wireless handheld microphone, comprising:
a main body having a conductive housing and a tubular shape for handheld operation of the microphone;
an opening included on a side surface of the conductive housing to provide access to one or more electronic components included within the main body;
a non-conductive cover coupled to the side surface of the conductive housing and covering the opening, the non-conductive cover having a curved shape to substantially match a curvature of the conductive housing; and
an antenna positioned underneath the non-conductive cover and within the opening on the side surface,
wherein the antenna has a generally curved shape that conforms to the curved shape of the non-conductive cover and elevates the antenna above the one or more electronic components within the opening.

2. The wireless handheld microphone of claim 1 , further comprising a display screen positioned within the opening of the conductive housing and adjacent to the one or more electronic components.

3. The wireless handheld microphone of claim 1 , further comprising a support structure configured to position the antenna against an underside of the non-conductive cover.

4. The wireless handheld microphone of claim 3 , wherein the support structure and the non-conductive cover are made of dielectric materials configured to increase an electrical length of the antenna.

5. The wireless handheld microphone of claim 1 , wherein the antenna is formed directly onto an underside of the non-conductive cover.

6. The wireless handheld microphone of claim 5 , wherein the non-conductive cover is made of a dielectric material configured to increase an electrical length of the antenna.

7. The wireless handheld microphone of claim 1 , wherein the antenna is configured for operation in at least one of the following frequency bands: 1.5 Gigahertz (GHz), 1.8 GHz, 2.5 GHz, 5.7 GHz, 6.9 GHz, and 7.1 GHz.

8. The wireless handheld microphone of claim 1 , further comprising a primary antenna coupled to a bottom end of the main body, the antenna operating as a secondary antenna.

9. The wireless handheld microphone of claim 8 , wherein the primary antenna and the secondary antenna transmit wireless signals over a common frequency band.

10. The wireless handheld microphone of claim 9 , wherein the wireless signals are control data signals.

11. The wireless handheld microphone of claim 10 , wherein the primary antenna is further configured for multi-band operation and for simultaneous transmission of audio and control data signals over different frequency bands.
