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 Rectangular Slot Resonator for Frequency Reconfigurable 2012-4-3 · an omni-directional pattern, which may be useful for wireless communication systems. The rectangular slot antenna is a variation of microstrip antenna with better gain, wider bandwidth and is less sensitive to manufacturing tolerances. In this paper, we have designed the dual frequency antenna and simulation was carried out using A NOVEL FREQUENCY RECONFIGURABLE SLOT … 2015-6-27 · 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- Frequency-Reconfigurable Stacked Patch Microstrip … 2014-7-4 · elements of the antenna, thus resulting in a beam-reconfigurable antenna that can switch the radiation pattern to a different direction. This study focuses on a frequency-reconfigurable antenna that is designed into a multilayer structure (stacked patch) with considerably higher gain. Moreover, a new coupling method is

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-

pattern reconfigurable antenna using annular slot antenna operating in low frequency. ... A pattern reconfigurable annular slot antenna that can switch beams in numerous directions has been designed and tested using Ansys HFSS.

FREQUENCY RECONFIGURABLE ANTENNA FOR KU -BAND APPLICATIONS In this study, a unique design in frequency reconfigurable antenna approach is proposed .The shown design in this paper can be used for Ku band downlink especially in satellites. A special em ployment includes a rectangular slot with four PIN diodes where the frequency reconfigurability is obtained. (PDF) Pattern and Frequency Reconfigurable Annular Slot ... 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.

Abstract— A novel frequency and pattern reconfigurable slot antenna is proposed. Slot antenna produces a bidirectional radiation pattern, thus a reflector is ...

Return loss and radiation pattern measurements and simulations are presented, which are in very good agreement. Index Terms—Annular slot antenna (ASA), frequency reconfigurability, pin diode, reconfigurable antenna, reconfigurable radiation pattern, slot antenna. I. Frequency and Pattern Reconfigurable Slot Antenna - IEEE ... Slot antenna produces a bidirectional radiation pattern, thus a reflector is positioned behind of the antenna to generate a directional radiation pattern. Two switches are placed in the slot to produce three reconfigurable frequency bands: at 1.82 GHz, 1.93 GHz and 2.10 GHz. The introduction of four slits at the edge of the ground plane offers ...
