Idea Propose: Antennas

1) Specifically, the physical piece of metal and copper wire that a receiver attaches to. Not a topic of much reputation and thus unlikely to repeat.

2) What variety of antennas that exist now and where or what application? What is their future design space?

3) Improving wireless infrastructure must include improving the methods that those wireless signals need to be transmitted and received on. This is done by an antenna; big, small, or otherwise.

Environmental challenges when designing and placing antennas for specific purposes or everyday use.

Antennas are a connection to the receivers and transmitters of the wireless world. Connected to your phone, car, or building; these pieces of metal are vial of signals to be sent and data to be moved.

Future wireless communications consist of massive multiple-input multiple-output (MIMO) systems which can make use of large antenna arrays but they would require a massive amount of power, feeding networks, and hundreds of high-resolution phase shifters. Instead of a traditional phased array of antennas, reconfigurable intelligent surfaces (RISs) offer a strong alternative. As a different kind of signal transmitter which consists of many nearly passive elements, the proposed design for a signal transmitter can handle arbitrary polarization and reduce power consumption with 2-bit phase quantization instead of the 1-bit of earlier designs.
