Frequency reconfigurable slot antenna using metasurface

Polarization reconfigurable slot antenna for 5.8 GHz ... In this paper, a CPW-fed circular polarization reconfigurable slot antenna is proposed. By simply changing the bias status of two PIN diodes through a T-type bias device, the antenna can work as two independent inverted L-shaped slots, and realize reconfigurable performances.

A new 4 × 4 unit cell artificial magnetic conductor metasurface is designed with a compact size at the same operating frequency of MTM-based CP antenna as a ground plane for the proposed antenna, which is found to be increased bandwidth … OSA | Complementary transmissive ultra-thin meta-deflectors for D.

In this paper, the detailed design and analysis of frequency reconflgurable slot-patch antenna with re°ector is presented. The proposed antenna is a combination of a microstrip patch and slot antenna. The slot is positioned at the ground plane underneath the patch. Three switches are used to reconflgure six difierent frequency bands.

[Moved]: Pattern and Frequency Reconfigurable Annular …

In this paper, a genetic algorithm optimization in conjunction with the internal multiport method is applied for determination of slot shape and PIN diode location in the ground plane for design of frequency reconfigurable patch antennas. Minimization of the number of diodes (as switches) is also considered.

AbstractA frequency-reconfigurable antenna designed using metasurface (MS) to operate at around 5 GHz is studied and proposed. The frequency-reconfigurable metasurfaced (FRMS) antenna is composed of a simple circular patch antenna and a circular MS with the same diameter of 40 mm and implemented using planar technology.

Balanis, C.A(1992),Antenna ... Reconfigurable Dipole Antenna - IEEE Xplore - In [3], a slot antenna using 2D metasurface can be reconfigured to operate in left-handed CP (LHCP), right-handed CP (RHCP) and linear polarization (LP) by mechanically rotating the metasurface. Compared to electrical reconfigurations such as switches, this mechanical reconfiguration requires movable parts, and has a high risk of mechanical I have done a seminar on frequency reconfigurable antenna Mar 25, 2015 · THESIS TOPIC IN ANTENNAS found this interesting.... well you can visit IEEE website and post the same where more tecnical people related to this may help you to greater extent.
