What are the benefits of smart antenna?

Advantages of Smart Antenna:

• ii) Increased Range. As the smart antenna focuses gain on the communicating device, the range of operation increases.
• iii) Security.
• v) Reduced Interference.
• iv) Increased bandwidth.
• i) Complex.
• ii) More Expensive.
• iii) Larger Size.
• iv) Location.

What is smart antenna What are categories of smart antennas What are the advantages of smart antenna?

Smart Antennas, also known as multiple antennas, adaptive array antennas, and so on is used to increase the efficiency in digital wireless communication systems. It works by taking the advantage of the diversity effect at the transceiver of the wireless system that is the source and the destination.

What are the different types of smart antennas?

There are basically two types of smart antennas: Switched beam systems and adaptive array systems. The switched beam system comprises only basic switching between separate directional antennas or predefined beams of an array while enabling high directivity and gain [2].

What are the applications of antenna?

Some common applications include vehicular, airborne, communications, SIGINT (signal intelligence), and ISR (intelligence, surveillance, and reconnaissance). While certain antenna types are more suitable for each of these specific applications, many of our products are versatile and multi-platform.

What is smart antenna technology?

Also known as adaptive antennas, these use an array of antennas in combination with smart signal processing algorithms that track the location of a mobile client device using techniques such as the direction of arrival of a signal.

How does a smart antenna differ from MIMO technology?

MIMO allows multiple antennas to send and receive multiple spatial streams at the same time. Smart antennas use spatial diversity technology, which puts surplus antennas to good use.

Why antenna is used in cars?

Car antennas are considered a significant automotive accessory as these are able to provide an uninterrupted transmission of wireless signals and radio waves in your vehicle. People often look for a replacement when their car antennas get damaged or become non-functional.

Who invented smart antenna?

physicist Karl F. Braun
The German inventor and physicist Karl F. Braun demonstrated beamforming for the first time in 1905. Braun created a phased array by positioning three antennas to reinforce radiation in one direction and diminish radiation in other directions.

What is an antenna used for?

An antenna is a metallic structure that captures and/or transmits radio electromagnetic waves. Antennas come in all shapes and sizes from little ones that can be found on your roof to watch TV to really big ones that capture signals from satellites millions of miles away.

Where are smart antennas used?

Smart antenna techniques are used notably in acoustic signal processing, track and scan radar, radio astronomy and radio telescopes, and mostly in cellular systems like W-CDMA, UMTS, and LTE. Smart antennas have many functions: DOA estimation, beamforming, interference nulling, and constant modulus preservation..

How does shark fin antenna work?

Each band or system — FM radio, AM radio, GPS, cellular — uses a separate antenna. There may be separate window traces for FM and AM, and antennas in the shark fin for GPS and cellular. Or, they may all be stuffed in the shark fin — if so, there’s often a short aerial protruding from the fin.

What is smart antenna and its advantages?

Smart antenna has become due to its tremendous potential to enhance performance of the nect generation wireless communication systems such as Mobile WiMAX, LTE, LTE advanced and WLAN. In this page we will cover smart antenna basics, types, applications and smart antenna advantages.

What is adaptive antenna arrays?

Adaptive antenna arrays are used for indoor systems where in received signals arrive via widely separetd paths. It is used where phased array smart antenna does not provide needed gain. The following pdf covers beamforming smart antenna design using FPGA .

What are the advantages of phase array smart antenna?

• Phased array smart antenna reduces probability of interference with narrower beam and adaptive array adjust the beam pattern to suppress the interference. • It also helps in multipath mitigation which supports three types of antenna diversity viz. spatial, polarization and angle diversity.

What are wearable antennas used for?

These antennas are commonly used in wearable wireless communication and bio-medical RF systems. Wearable antennas are used within the context of Wireless Body Area Networks (WBAN). In a WBAN, antenna is the key component that supports wireless communication, which include in-body communication, on-body communication and off-body communication.
