A planar polarization-reconfigurable metasurfaced antenna (PRMS) designed using metasurface (MS) is proposed. The PRMS antenna consists of a planar MS placed atop of and in direct contact with a planar slot antenna, both having a circular shape with a diameter of 78 mm (0.9 $\lambda_{0}$ ), making it compact and low profile.

A Reconfigurable Wideband and Multiband Antenna ... - IEEE ... Coupling between the two patch elements plays a major role for achieving the wide bandwidth and the effects of mutual coupling between the patch elements are also studied. Index Terms—C-slot, cognitive radio, patch antenna, reconfigurable antenna, slot antenna, small antenna, switched antenna, wideband antenna. I. INTRODUCTION P Design and Characterization of a Miniaturized Antenna Based ... The measured performance of the proposed antenna in this paper and the metasurface antenna operating at around 5 GHz is summarized in Table 1. As compared to those reported in previous works, we can see that our antennas achieve a good compromise between gain, antenna footprint, and operational frequency bandwidth.

The PRMS antenna consists of a planar MS placed atop of and in direct contact with a planar slot antenna, both having a circular shape with a diameter of 78 mm (0.9 $\lambda_{0}$ ), making it compact and low profile. Planar wideband circularly polarized metasurface-based ... Antenna II is a slot antenna using a conventional metasurface composed of 4 × 4 square patches. Antenna III is the proposed structure. For fair comparison, the design parameters of Antennas I and II are chosen to be the same as those of the single element. Without the metasurface, Antenna I is a lP slot antenna with the resonance Frequency Reconfigurable U-Shaped Microstrip Patch Antenna ... reconfigurable slot antenna has the same radiation pattern at all frequencies. ... of the antenna as a function of frequency are investigated .

Polarization reconfigurable slot antenna for 5.8 GHz 1. Introduction. Circular polarization reconfigurable antennas have drawn lots of attention in recent years , , since they have both the merits of circular polarization antenna (capable of mitigating the multipath effect and flexibility in the orientation of the transmitting and receiving antennas , ) and reconfigurable antenna (satisfy the requirements for increased functionality within a
