- Novel Antennas

A novel antenna refers to a new or unique antenna design that offers improved capabilities or functionalities compared to traditional antennas. These antennas often incorporate innovative technologies or designs to achieve specific goals like enhanced beam steering, multi-frequency operation, or improved bandwidth. 

In essence, a novel antenna is a departure from conventional designs, often leveraging advanced technologies and concepts to achieve enhanced performance, flexibility, and capabilities in wireless communication and related fields. Here's a more detailed look at what constitutes a novel antenna:

Key Features and Characteristics:

- Multiple-Input, Multiple-Output (MIMO)  Antennas

Multiple-Input Multiple-Output (MIMO) is an antenna technology for wireless communications in which multiple antennas are used at both the source (transmitter) and destination (receiver) at the same time. The combination of antennas at both ends of the communication circuit allows data to be transmitted over multiple signal paths simultaneously, minimizing errors, optimizing data speed and increasing the capacity of radio transmissions.

Creating multiple versions of the same signal increases the signal-to-noise ratio and error rate by giving data more opportunities to reach the receiving antenna without being affected by fading. By increasing the capacity of radio frequency (RF) systems, MIMO creates more stable connections and less congestion.

MIMO technology is widely used in Wi-Fi networks and cellular fourth-generation (4G) long-term evolution (LTE) and fifth-generation (5G) technologies, including law enforcement, broadcast television production, and government. It can also be used on wireless local area networks (WLANs) and is supported by all 802.11n wireless products.

All wireless products with 802.11n support MIMO. The technology helps allow 802.11n to reach higher speeds than products without 802.11n. The 3rd Generation Partnership Project (3GPP) added MIMO to Release 8 of the mobile broadband standard.
