Abstract

An information handling system includes a triangular chassis and a plurality of antennas that provide optimized coverage in all directions around the triangular chassis. An antenna may be operated from each vertex of the triangular shaped base chassis. Alternatively, an antenna may be operated from each of three main side surfaces of the triangular shaped base chassis. One or more of the antennas can be selected for communication based on the ability to communicate with external network components. Disclosed systems provide omnidirectional coverage around the triangular chassis while minimizing the effects of shadowing caused by abase chassis.

Claims

1. A method of transmitting and receiving data, the method comprising:

operating a first antenna proximate to a first vertex of an information handling system chassis, wherein;

the chassis has a generally triangular profile comprised partly of metal;

the information handling system comprises a CPU, a graphics processor, a power supply, RAM memory, and a network interface device;

a location of the first antenna proximate to the first vertex minimizes operating against a shadow effect of the chassis;

operating a second antenna proximate to a second vertex of the chassis to further minimize the shadow effect by the chassis; and

operating a third antenna proximate to a third vertex of the chassis.

2. The method of claim 1, wherein the first antenna and the second antenna each comprise multiple antenna elements.

3. The method of claim 1, wherein the first antenna and the second antenna are omnidirectional.

4. The method of claim 1, further comprising:

operating a radio within the chassis to send information to and receive information from the first antenna, the second antenna, and the third antenna.

5. The method of claim 1, further comprising:

monitoring the operational effectiveness of the first antenna and the second antenna.

6. The method of claim 5, further comprising:

determining which of the first antenna and the second antenna should be used for sending or receiving information; and

selecting one of the first antenna or the second antenna based on the determining step.

7. An information handling system comprising:

a chassis comprising a triangular profile comprised partly of metal;

a set of antennas comprising;

a first antenna proximate to a first vertex of the triangular profile to minimize operating against a shadow effect of the chassis;

a second antenna proximate to a second vertex of the triangular profile; and

a third antenna proximate to a third vertex of the triangular profile;

a CPU, a graphics processor, a power supply, RAM memory, and a network interface device within the chassis; and

a radio communicatively coupled to the first antenna and the second antenna.

8. The information handling system of claim 7, wherein the first antenna and the second antenna are omnidirectional.

9. The information handling system of claim 7, wherein each of the first antenna and the second antenna includes multiple antenna elements.

10. The information handling system of claim 7, wherein the first antenna is mounted under a plastic chassis assembly.

11. The information handling system of claim 10, wherein:

the radio comprises a transceiver enabled for sending and receiving information through each of the first antenna and the second antenna.

12. The information handling system of claim 7, wherein at least one of the first vertex, the second vertex, and a third vertex is chamfered.

13. The information handling system of claim 7, further comprising:

the triangular profile forms a front of the chassis;

a further triangular profile forms a back of the chassis; and

each of the first antenna, the second antenna, and a third antenna runs in a direction from the front of the chassis to the back of the chassis.

14. An information handling system comprising:

a triangular chassis partly of metal comprising;

a first vertex;

second vertex, and

third vertex;

a first antenna of the one or more antennas is located proximate to the first vertex to minimize operating against a shadow effect of the chassis

a second antenna of the one or more antennas is located proximate to the second vertex; and

a third antenna of the one or more antennas is located on the triangular chassis opposite to the first or the second vertex; and

a CPU, a graphics processor, a power supply, RAM memory, and a network interface device located within the triangular chassis.

15. The information handling system of claim 14, further comprising:

a radio within the chassis to send information to and receive information from the first antenna, the second antenna, and the third antenna.

16. The information handling system of claim 15, wherein one or more of the first vertex, the second vertex, and the third vertex is chamfered.

17. The information handling system of claim 15, wherein the one or more antennas are omnidirectional.

18. The information handling system of claim 15, wherein each of the one or more antennas include multiple antenna elements.

19. The information handling system of claim 14, wherein the triangular chassis further comprises:

a front triangular profile and a rear triangular profile that is generally parallel to the front triangular profile;

wherein the one or more antennas include a first antenna, a second antenna, and a third antenna; and

wherein each of the first antenna, the second antenna and the third antenna is located between the front triangular profile and the rear triangular profile.

20. The information handling system of claim 15, further comprising:
