dc.description.abstract  AbstractReconfigurable antennas have ability to modify their geometry and behavior to adapt to changes in environmental conditions or system requirements (such as enhanced bandwidth, change in operating frequency, polarization, radiation pattern etc.). Reconfigurable antennas can deliver the same throughput as a multi-antenna system using dynamically variable and adaptable single-antenna geometry without increasing the real estate required to accommodate these antennas. We study the channel models to know how to represent the channel characteristics, the indoor channel model discussed such as small scale fading channel models (Nakagami, Rayleigh ).In this project we deal with Wi-Fi technology and we use Wireless InSite to generate three different channel states in indoor environment by using dipole reconfigurable antenna in the transmitter, in each state of the transmitter it  generate its own channel state the system will compute the BER performance by each state separately. But if we make the transmitter reconfigurable three channel state can occur on the receiver, so the receiver will work on the best of the three states in term of the received power, after the receiver move the received power maybe become small, therefore the receiver give feedback that the received power had reduced and since of the re-configurability in the transmitter, the receiver will scan for another state that is better in power. As a result the BER performance of the system by using the re-configurability term will be better than using only fixed antenna. The power needed to reach 10^-3  in reconfigurable antenna is less than the best antenna state by 15db. However in this project we apply anther reconfigurable methods that is to frequency reconfigurable antenna to make the system work in two frequency 2.4 and 3.5 Wi-Fi and WIMAX technologies, we make the design by using patch array antenna with PIN switch, and the design done by HFSS.en
