Smart antennas are antenna arrays having smart signal processing algorithms, and are utilized for identifying spatial signal signatures. Smart antennas have been utilized notably for acoustic signal processing, radio astronomy, scanning and tracking radar, and radio telescopes, etc. These antennas are used to bolster the range of the signal, for combating signal fading, interfering signal suppression, and in wireless systems for enhancing their capacity.

The Smart Antenna Market in terms of revenue was valued at US$14.72 bn in 2014, which is expected to reach US$30.12 bn by 2023, at a CAGR of 8.5% from 2015 to 2023.

The global smart antennas market for is majorly fuelled by the rising usage of smart antennas within smartphones. In addition, the rising demand for smart antennas within wireless communications is also impacting the market positively. Furthermore, the increasing requirement for swift data transmission within modern communication systems for high-speed downloading and web browsing has resulted in enhanced wireless transmission efficiency by companies, thus impacting the market positively.

When compared to normal antennas, smart antennas offer the advantages of:

> Capacity Enhancement
> Coverage Extension
> Increased Transmission Bandwidth
> Reduction of Multipath Fading

These antennas have two basic functions, namely:

> Estimation of Direction of Arrival (DOA)
> Beam Forming

Smart antenna systems estimate the DOA of a signal by using techniques such as multiple signal classification (MUSIC), matrix pencil method or estimation of signal parameters via rotational invariance techniques (ESPRIT).

Beam forming method is used for creating radiation pattern of antenna array by adding the phases of signals in the direction of desired mobiles/targets and nulling the mobiles/ targets that are undesired.

By discharging these functions, smart antennas optimize their reception and/or radiation pattern automatically in response to the signal environment.

Many factors such as increasing demand for smart antennas in wireless communication and increasing application of smart antennas in smart phones are driving the growth of overall smart antenna market. Smartphone have become a viable alternative to laptops and personal digital assistants (PDAs), offering features such as SMS and voice messages coupled with multimedia functionality, internet applications, inbuilt GPS capabilities and high data processing capabilities. Furthermore, the healthy economic growth of emerging markets such as India and China represent massive markets for the consumer electronics for their gigantic population. This in turn, is positively impacting the growth of the smart antenna market globally. Entry of new players in the emerging markets coupled with better and innovative Smart Antenna has led to the increase in competitiveness in the market. Wireless systems are an essential part for mobile communications and they are becoming more important with the growing demand. Moreover, Smart antenna systems have emerged as a promising technology for enhancing the spectrum efficiency of the present as well as future wireless communication systems by exploiting the spatial domain. Smart antennas can significantly improve the performance of wireless systems and economies for a range of potential users. for accessing information.

The adoption of tablets and smart phones is soaring and as people stream videos, share photos and browse the web, they are increasingly using more data over the airwaves than before. Mobile traffic across the globe is doubling each year and the exponential growth is expected to continue in the coming years. In order to expand the capacity of 4G LTE cellular networks, companies have devised all sorts of fixes, including ones involving smarter coordination and smaller cells. However, these solutions can sustain the oncoming surge in traffic only for next few years. Therefore, the development of 5G technology systems is being investigated and this technology for cellular systems is expected to be rolled out around 2020. The current status of 5G technology for cellular systems is very much in the nascent stage and companies are looking into technologies which could be used to be a part of this system. The concepts that are being investigated and developed for the new 5G technology include pervasive networks, group cooperative relay, cognitive radio technology, wireless mesh networking and smart antennas. Smart antennas are expected be a major element in any 5G cellular system.. Smart antennasalso help to increase the overall cell capacity and limit the signal interference. Smart antennas using MIMO (multiple-input multiple-output) systems are expected to enable new spectrum for the upcoming 5G networks. Multiple transmit and receive antennas (MIMO channels) feature in smart antennas offer much higher spectral efficiency than conventional antennas. Thus in turn it increases the data rate and improves quality of wireless transmission, which is restricted by local scattering, multipath propagation and interference. Therefore, the emergence of 5G technology is expected to drive the market.
