This Thesis presents the design and development of a reconfigurable both in frequency and radiation pattern Annular Slot Antenna (ASA). The antenna is fabricated on Duroid with dielectric constant 6.15. The ASA operates in three different frequencies: 5.2, 5.8 and 6.4 GHz. The matching at those frequencies is achieved using linear stubs. PIN diodes are used as switches to connect/disconnect the stubs to the microstip feed line. The use of PIN diodes along the slot allows the steering of the radiation pattern and therefore the position of a radiation pattern null is directed in three pre-selected directions.
