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. At the two RF ports an impedance transformer matches the 50 Ω feed line to the patch.Fig. 1(a) shows a square ring slot with outer dimensions l × w etched in the ... Single-, Dual- and Triple-band Frequency Reconfigurable ... 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 A Frequency Reconfigurable Rotatable Antenna Design for ... A Frequency Reconfigurable Rotatable Antenna Design for Cognitive Radio Systems G. Prema P. Gayatri ... A reconfigurable C-slot microstrip patch antenna is proposed in [4]. The antenna can operate in dual ... to act like a vertical antenna. The antenna radiation pattern at Φ=0⁰ and Φ=90⁰ at Position-1 for f=7.12 A NOVEL FREQUENCY RECONFIGURABLE SLOT ANTENNA - IJAET A novel frequency reconfigurable slot antenna is designed for cognitive radio system. In cognitive radio system the two antennas are required one is a wideband antenna and another is frequency reconfigurable antenna. In this work a frequency reconfigurable slot antenna is designed between the switchable frequency range i.e 7.34-

Draft Version A Reconfigurable Radiation Pattern Annular ... pattern reconfigurable antenna using annular slot antenna operating in low frequency. A shorting pin is inserted to allow the annular slot antenna to have an omnidirectional radiation pattern like a monopole antenna. The reconfigurable antenna consists of numerous metal cylinders arranged around the annular slot antenna.
