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 ...

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 ...

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

Reconfigurable Antennas: Design and Applications

Proceedings of the IEEE, 2015
The advancement in wireless communications requires the integration of multiple radios into a single platform to maximize connectivity. In this paper, the design process of reconfigurable antennas is discussed. Reconfigurable antennas are proposed to cover different wireless services that operate over a wide frequency range.

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

Novel Reconfigurable Microstrip Antenna

2008 IEEE Region 10 and the Third international Conference on Industrial and Information Systems, 2008
A microstrip square patch antenna is designed and analyzed with re configurability in frequency and polarization. The patch contains two orthogonal slots and two rectangular patches added across the length and width. The diversity in frequency and polarization is achieved through the use of PIN diodes.

Banwidth Reconfigurable Filtering Antenna

Wireless Personal Communications, 2019
A microstrip bandwidth reconfigurable filtering antenna is implemented by simply tuning the transmission zeroes. The proposed filtering antenna is developed by integrating the filter characteristics into the 50 Ω microstrip feed line of the antenna through two independent coupled resonators.

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
