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
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 ...

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 (PDF) Design of Frequency- and Pattern-Reconfigurable
