Design and Implementation of Reconfigurable Antenna - IRJET
In this letter, we have designed a new printed slot-antenna with multiple reconfigurable bands and wide operating range. The structure is based on a square patch antenna with centered Koch-Island fractal slot and integrated switches (inside the slot) for frequency reconfigurable property. Design and Implementation of Reconfigurable Antenna redistribute the antenna currents. Radio frequency micro-electromechanical systems (RF-MEMS) have been proposed for integration into reconfigurable antennas since 1998 [5]. Many designs have resorted to RF MEMS to reconfigure their performance. RF MEMS based reconfigurable antennas rely on the mechanical movement of these switches to achieve A Frequency Reconfigurable Rotatable Antenna Design for ...

Frequency Reconfigurable Circular Patch Antenna with an Arc ... 4. Results and Discussion. The proposed frequency reconfigurable antenna is based on back-fed circular patch antenna with an arc-shaped slot (length of 30 mm and width of 2 mm) in the ground plane. Tunable dual-frequency RF MEMS rectangular slot ring antenna Furthermore, for relatively low frequency applications, such as X-band or lower frequencies, the antennas cover a large portion of the wafer. Thus the cost of an antenna, especially array antenna, monolithically integrated with RF MEMS components may be higher compared to the antenna produced on a regular substrate. Reconfigurable antenna - Wikipedia A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the ...
