A wide band Frequency Reconfigurable Rectangular Slotted Self Similar Antenna has been proposed in this paper. The rectangular slotted patch is repeated for two iterations at different scales and is separated by means of Radio Frequency Micro Electro Mechanical Systems (RF MEMS) switches in order to pro-vide reconfigurability.

On the design of an Ohmic RF MEMS Switch for reconfigurable ... The design of a reconfigurable antenna using RF MEMS switches could be implemented either based on the hybrid mode, that is using individual RF MEMS switches which should be bond in the PCB as shown in Fig. 1, or the integrated mode, where each switch is fabricated on the same substrate with the antenna

a larger antenna size. II. RECONFIGURABLE ANTENNAS A reconfigurable antenna is an attractive feature in a modern wireless communication System because of its flexibility for use in multiple applications such as multiband and point-to-multipoint. Reconfigurable antenna systems were first introduced in 1998 by Brown. In the 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 ...

The students demonstrated a miniature reconfigurable antenna that was designed and fabricated on a high-resistivity silicon substrate. The antenna can be integrated with a MEMS actuator to reconfigure the operating frequency. RFMEMS switches are used to perform switching between two different frequency bands.

Yagi Dipole Antenna - IEEE Xplore - MAFIADOC.COM V. CONCLUSION A new RF MEMS-integrated millimeter-wave frequency reconfigurable quasi-Yagi antenna is proposed. The operation frequency of the antenna is switchable between the millimeter wave 60 GHz WPAN band (57-66 GHz) and E-band (71-86 GHz) by actuating of the RF MEMS switches employed on the driven and director dipole elements. UWB Sensing Antenna, Reconfigurable Transceiver and ... For this it must consists of spectrum sensing circuit and a reconfigurable transceiver consisting of reconfigurable antenna. This paper discuss the single module of reconfigurable transceiver which dynamically allocates two different frequencies 2.4 and 3.1 GHz for transmission. 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 Design of frequency reconfigurable multiband compact antenna ...
