There are various wireless systems and there are different challenges, requirements and novel solutions for such systems as well. Similarly there are different designs followed for the antennas that are used for such systems. There are different types of antennas but you will see the cellular phone and other wireless communication antennas most in the market and is widely in use. Over the years there has been significant progress in the design of these mobile phone and wireless communication antennas, especially within the last one and a half decade. The new developments in such antennas have given rise to compact MIMO terminals and LTE.

The Wideband Antenna

The magneto electric dipole or the wideband antenna, as it is commonly known as, is among the most used wireless communications antennas in the modern market. Used primarily by the base stations in mobile communications, these antennas has resulted in better receipt and emitting of signals and thereby bettering the communication system on the whole. There are some stringent requirements and set of codes imposed on the design of these antennas for the base stations for mobile communications. The novel ad high performance wideband magneto electric dipole is the key structure for such antennas which has and will be extensively used by the base stations for various applications in mobile communications in the future.

The Unlicensed Ultra Wideband System

You will also find another type of antenna in the market which is the unlicensed ultra wideband system or UWB. The introduction of this type of antenna has enabled in the effective use of limited RF bandwidth. With the help of this now it is possible for wireless connectivity at high data rate within a short range. It has also facilitated in the long range versions of rate applications of low data. There are some typical attributes in these UWB antennas that are suitable for short range broadband communications, body area networking and radar sensing. The Omni antennas are also found that are for radiating radio wave uniformly in one plane and in all directions.

The Wi-Fi Antennas

Within the category of wireless communications antennas the Wi-Fi antennas are also used for fast and wireless internet connectivity. These have critical constraints that limits in the performance of such antenna in terms of cost and size. This is an antenna that is integrated for multiple functions in one system. Though there are some design challenges of these antennas but it is growing in popularity with each passing day. With the advancement of technology manufacturers are looking in to the practical issues in these antenna systems that includes dual and multi band operation, diversity and MIMO performance, small form, low fabrication cost and much more to better it soon.

Environment Of Application

The performance of the wireless communication antennas largely depend on the environment of application and the working conditions. The RIFD technology has taken all the constraints in to consideration with a challenge to improve the designs to overcome such constraints. Use of an automated EM simulator, an RFID tag to sense the level of temperature, displacement, humidity, and liquid level has somewhat helped in reducing the issues in hand.
