Pattern and Frequency Reconfigurable Annular Slot Antenna ... CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract—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 of a Duroid substrate and the microstrip feeding line with the matching network is fabricated on the opposite side of ... Design and Development of an Annular Slot Antenna (ASA ... A reconfigurable annular slot antenna with a constant-frequency controlled radiation pattern using pin diodes was presented. The proposed antenna is fabricated on inexpensive material, has compact size, radiates with high efficiency and can be easily integrated with other components. The controlled

A compact frequency reconfigurable antenna proposed in [12] utilizes a simple square shaped radiating patch for Bluetooth, WLAN, and WiMAX applications. Three pin diodes are inserted in ground plane that controls switching bands. A novel frequency reconfigurable antenna using the FR4 substrate that switches between an ultra wide band,
