MEMS-based reconfigurable antennas
2004 IEEE International Symposium on Industrial Electronics, 2004In 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

Pattern reconfigurable compact antenna
2009 IEEE MTT-S International Microwave Workshop on Wireless Sensing, Local Positioning, and RFID, 2009This 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.

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), 2002The 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 ...

Multistandard reconfigurable PIFA antenna
Microwave and Optical Technology Letters, 2006In 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), 2013A 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.

2010 Loughborough Antennas & Propagation Conference, 2010
A simple programming technique (MATLAB) has been written for the analysis of a beam reconfigurable antenna array. The technique is based on the calculation of mutual impedance using Induced EMF method. This can be applied to an array of dipoles arranged in various configurations.

Reconfigurable Vivaldi antenna
Microwave and Optical Technology Letters, 2010AbstractA reconfigurable Vivaldi antenna is presented.It has a capability to operate in a wideband mode (2–8 GHz) and three different sub‐bands (2.5, 5, and 7.5 GHz) by reconfiguring the antenna geometry. The measurement results with ideal switches demonstrate the performances of the proposed designs.
