|Title||Design of Frequency and Pattern Reconfigurable Antenna for UWB Applications|
|Title in Arabic||تصميم هوائي لتطبيقات النطاق العريض مع خاصية تغيير التردد ونمط الانبعاث|
The main target of this proposed work is designing antenna with various features and characteristics particularly frequency agility and pattern re-configurability. Reconfigurability is the capacity to change an individual radiator’s fundamental operating characteristics through electrical, mechanical. This thesis presents both radiation pattern and frequency reconfiguration of Ultra Wide Band (UWB) antenna. Novel antenna structure is proposed here with circular shapes added to the feed line and around the main circular patch for both frequency and pattern reconfiguration. PIN switches are used in the design to select the frequency band and to re-configure the antenna radiation pattern. The antenna can operate in eight frequency bands and it can be re-configured to operate in one of eight different radiation patterns. The antenna return loss, radiation patterns and gain were simulated using CST Microwave Studio. The simulation results showed gain greater than 4 dBi for all the reconfigured patterns, and the return loss was better than 6.5 dB. Keywords: Reconfigurability, (UWB) antenna, CST Microwave Studio.
