Reconfigurable MEMS Antennas

2008 NASA/ESA Conference on Adaptive Hardware and Systems, 2008
This paper reviews the work carried out in the field of reconfigurable antennas, and in specific the reconfigurable MEMS (Micro-Electro-Mechanical Systems) antennas. The application of MEMS to antennas is studied and compared with the various implementations such as pattern reconfigurable MEMS antennas, mechanically actuated MEMS antennas, capacitive ...

Reconfigurable printed antennas

IETE Journal of Research, 2013
AbstractThe concept of reconfigurability in antennas and their types are discussed in detail in this paper. Novel reconfigurable antenna structures for modern wireless communication application are presented. PIN diodes that are biased with on-board biasing circuitry are used to achieve reconfigurability in these antennas.

Planar reconfigurable antennas

2006 First European Conference on Antennas and Propagation, 2006
In this paper it is shown that planar reconfigurable antennas can cover a wide range of designs such as fractal antennas, triangular antennas, monopole, dipoles, log-periodic etc. Some of these designs can also be used to yield tunable electrically small antennas for miniature wireless device applications.

MEMS reconfigurable antennas

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, 2007
The 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

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 ...

Reconfigurable Antenna Design for nanosatellites

2012 IEEE First AESS European Conference on Satellite Telecommunications (ESTEL), 2012
Innovative Antenna Design has recently become as one of most vital subsystem of Satellite Communication. In small satellites however, this subsystem is often overlooked, either due to consideration of weight or available space. Using traditional design approach is not feasible and does not offer any significant benefits. With increasing availability of

Reconfigurable Antenna Simulation: Design of Reconfigurable Antennas with Electromagnetic Simulation

IEEE Microwave Magazine, 2013
This article describes how state-of-the-art electromagnetic simulation tools can be used to simulate and optimize the complex geometries and system behavior of reconfigurable antennas. While a short overview of the main principles of reconfigurability is given, this is not the main focus of this article, and far more extensive reviews of reconfigurable

An overview of antenna reconfiguration technologies : Overview of Reconfigurable Antenna

2019 International Conference on Information Technology and Computer Application (ITCA), 2019
All those antennas who have the ability to show modifications in their frequency, radiation pattern and polarization mode in a reversible and much-controlled way are known as reconfigurable antennas. These are different from other good antennas since their mechanism of reconfiguration is located inside the antenna, and reconfigured in real time ...

Reconfigurable hilbert curve patch antenna

IWAT 2005. IEEE International Workshop on Antenna Technology: Small Antennas and Novel Metamaterials, 2005., 2005
A novel reconfigurable Hilbert curve patch antenna (RHCPA) is proposed. The patch is figured using the third order Hilbert curve. By introducing some slots, at least two configurations of the antenna with different radiation patterns are formed. Micro-electro-mechanical systems (MEMS) switches are used to change the antenna configuration and hence the ...
