The reconfigurable ASA proposed in this paper operates at three frequencies with a central frequency at 5.8 GHz, and it also Index Terms—Annular slot antenna (ASA), frequency reconfig- has a reconfigurable radiation pattern that can position a null urability, pin diode, reconfigurable antenna, reconfigurable radia- tion pattern, slot antenna. Pattern and Frequency Reconfigurable Annular Slot Antenna ... PDF | This paper presents the use of pin diodes to reconfigure the impedance match and modify the radiation pattern of an annular slot antenna (ASA). The planar antenna is fabricated on one side ... Frequency and pattern reconfigurable Yagi patch antenna ... By changing the states of the slots etched on different parasitic element patches, directions of the radiation pattern can be changed. Thus, a design that is reconfigurable in both frequency and radiation pattern is accomplished. As a proof of concept, five models are fabricated and tested.

Fig. 1 shows the geometry of proposed quad polarization and frequency reconfigurable antenna with detailed dimensions. It consists of a square patch of side a printed on RT Duroid substrate of ε r = 2.2 and thickness h = 3.2 mm. Single-, Dual- and Triple-band Frequency Reconfigurable Antenna The antenna has applications in Bluetooth, WiMAX, and WLAN systems. This paper proposes a new design for a frequency reconfigurable multi-band antenna based around a slot di-pole. Three pairs of pin-diode switches are placed across, the dipole arms. It is possible to reconfigure the operating frequency of the antenna, by altering the states of the
