wireless communication using omnidirectional antennas communication is made in directions not pointing towards the recipient resulting in energy waste‚ and producing traffic collisions and reducing the battery life. One way of reducing this problem is to use of smart antenna that uses selectable radiation patterns depending on the situations. These antennas provide the ability to sense the direction of incoming signals. Smart antennas are the antenna arrays with smart signal processing algorithms used

Multiple-Input Multiple-Output Wireless Communication Systems Using Antenna Pattern Diversity Liang Dong‚ Hao Ling‚ and Robert W. Heath‚ Jr. Department of Electrical and Computer Engineering The University of Texas‚ Austin‚ TX 78712 Abstract— Multiple-input multiple-output (MIMO) wireless communication systems employ multiple transmit and multiple receive antennas to obtain significant improvement in channel capacity. However‚ the capacity is limited by the correlation of subchannels in non-ideal

ABSTRACT Adaptive active phased array radars are seen as the vehicle to address the current requirements for true ‘multifunction’ radars systems. Their ability to adapt to the enviournment and schedule their tasks in real time allows them to operate with performance levels well above those that can be achieved from the conventional radars. Their ability to make effective use of all the available RF power and to minimize RF losses also makes them a good candidate for future very

derivation of the Friis Equation‚ consider two antennas in free space (no obstructions nearby) separated by a distance R: Figure 1. Transmit (Tx) and Receive (Rx) Antennas separated by R. Assume that Watts of total power are delivered to the transmit antenna. For the moment‚ assume that the transmit antenna is omnidirectional‚ lossless‚ and that the receive antenna is in the far field of the transmit antenna. Then the power density p (in Watts per square

A Technical Comparison of 802.11n to 802.11g A Technical Comparison of 802.11n to 802.11g Abstract 802.11n was developed to address issues of distance and speed. These were issues with wireless g and especially big issues with legacy devices that were used previously. Wireless N devices allow for a wider range by using multiple-input multiple-out and multiplexing allowing more data to be sent at a given time than before in previous a/g devices. It also allows for better communication between
