MEMS-based reconfigurable antennas

2004 IEEE International Symposium on Industrial Electronics, 2004
In this paper, two frequency reconfigurable antennas using the ON/OFF states of a microelectromechanical system (MEMS), are presented. A multifrequency planar inverted-F antenna (PIFA) is designed with a L-shaped open slot upon its main plate. As a proof-of-principle, an ON state RF MEMS switch, modeled by a piece of copper (1x1 mm/sup 2/), is inserted

Frequency reconfigurable active antenna

2014 International Symposium on Antennas and Propagation Conference Proceedings, 2014
The objective is to design a frequency reconfigurable active antenna which involves the integration of active device such as FET with a passive structure. Here the dual port dual band antenna is independently designed and later connected to one port amplifier using matching network.

MEMS-switched reconfigurable antennas

IEEE Antennas and Propagation Society International Symposium. 2001 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.01CH37229), 2002
The integration and use of RF MEMS switches in microstrip patch antennas and feed structures were investigated for developing reconfigurable multi-band antennas. The current application focuses on the development of a dual L/X-band antenna that would support several satellite or UAV-based communications and radar applications such as SAR, terrain ...

Pattern reconfigurable compact antenna

2009 IEEE MTT-S International Microwave Workshop on Wireless Sensing, Local Positioning, and RFID, 2009
This paper presents a design of an compact antenna providing two diverse radiation patterns, which results from the excitation of two different modes. The antenna consists of a capacitively fed annular ring microstrip antenna, which can be shorted via shorting pins on its edges using pin diodes.

On the Applications for a Radiation Reconfigurable Antenna

Second NASA/ESA Conference on Adaptive Hardware and Systems (AHS 2007), 2007
In this work, applications involving a radiation reconfigurable antenna are presented and discussed. The antenna is capable of reconfiguring its radiation pattern from broadside to endfire over a common impedance bandwidth. After outlining the operation and radiation behavior of the single element its use in multiple antenna systems, such as multiple ...

Multistandard reconfigurable PIFA antenna

Microwave and Optical Technology Letters, 2006
In this article, a frequency reconfigurable antenna using the ON/OFF states of a MEMS (micro‐electro‐mechanical system) switch is presented. This structure is based on a planar inverted‐F antenna (PIFA), designed with an L‐shaped open slot etched upon its main plate.

Piezoelectric reconfigurable antenna

2013 Loughborough Antennas & Propagation Conference (LAPC), 2013
A novel approach to tuning an inverted F antenna is investigated by using PZT materials that switch elements into contact using a dc control voltage to reconfigure the IFA structure. This produces a prototype reconfigurable antenna which can be finely tuned over a 9% bandwidth.

Wirelessly reconfigurable antenna

2015 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2015
In this paper, we describe a reconfigurable antenna with switches on the antenna elements that are powered wirelessly, by the antenna itself. Control signals for individual switches are part of the antenna transmission. We describe the theory of operation and provide simulation results for a three-element parasitic dipole antenna array with two ...
