Abstract

An antenna system for a large appliance is disclosed herein. The antenna system comprises a large appliance having a front surface and a rear surface, a first antenna mounted on the rear surface, a second antenna mounted on the rear surface, a combiner in communication with the first antenna and the second antenna, a radio, a processor, and a wireless access point. The combiner selects the strongest signal of the first antenna and the second antenna to receive a wireless signal from the wireless access point.

Claims

1. An antenna system for a large appliance, the antenna system comprising:

the large appliance having a front surface and a rear surface;

a first antenna centrally mounted on the rear surface;

a second antenna centrally mounted on the rear surface;

a combiner having a shield case and in communication with the first antenna and the second antenna;

a radio;

a processor; and

a wireless access point positioned forward of the display surface of the large television and operating on an 802.11 communication protocol;

wherein the combiner is a passive switch that uses the strongest signal of the first antenna and the second antenna, and a difference between the signal from the wireless access point received at the first antenna and the second antenna ranged from 6 dB to 10 dB;

wherein the large appliance has a surface area of at least nine feet and is a 4K high definition television;

wherein the large appliance comprises a metal surface that blocks antenna signals from the wireless access point.

2. The antenna system according to claim 1 wherein the first antenna and the second antenna are separated by 30 mm.

3. The antenna system according to claim 1 wherein the large appliance has a surface area of at least five times the wavelength of the antenna signal.

4. The antenna system according to claim 1 wherein the antenna system is a MIMO antenna system.

5. The antenna system according to claim 1 wherein the antenna system is a MIMO antenna system with a 2×

2 dual band antenna and further comprises a single BLUETOOTH antenna and a 5G antenna.

6. The antenna system according to claim 1 wherein the antenna system is a MIMO antenna system with a 3×

3 antenna on 802.11ac and 3×

3 antenna on 802.11n.
