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 ...

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.

On the Applications for a Radiation Reconfigurable Antenna
Second NASA/ESA Conference on Adaptive Hardware and Systems (AHS 2007), 2007In 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 ...

Reconfigurable Metal Chassis Antenna
IEICE Transactions on Communications, 2019Smartphones for wireless communication typically consist of a large area frontal liquid crystal display (LCD), which incorporates a metal back plate, and a back cover chassis made from metal. Leveraging this structure a new approach to construct antennas for smartphones is proposed where the complete metal back cover chassis and LCD back plate are used

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.

International Journal of RF and Microwave Computer-Aided Engineering, 2001
New architectures for microelectromechanical system (MEMS) reconfigurable Vee-antennas and RF switches are presented. The planar antenna structure can be dynamically reconfigured to steer the radiation beam or change the shape of the beam using electrically-controlled microactuators. The radiation patterns and antenna impedance were investigated with a

Reconfigurable Semiconductor Antenna
2007 9th International Conference - The Experience of Designing and Applications of CAD Systems in Microelectronics, 2007The results of investigation of the semiconductor antenna with electronically reconfigurable aperture has been presented in this paper. The semiconductor antenna means that the antenna utilizes the semiconductor as a substrate, which parameters can be varied. The key element of the reconfigurable antenna is a surface PIN (SPIN) diode whose conductivity

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.
