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 ...

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.

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.

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

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.

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
