“…These antennas can be used for avoiding multipath effects, for polarization coding, and for enhancing system capacity. Different CP antenna designs have been developed to achieve reconfigurable polarization, including patch antennas [1], [2], aperture-coupled patch antennas [3], [4], crossed-dipole antennas [5], sequentially rotated array antennas [6], loop antennas [7], and metasurface-based antennas [8], [9]. In addition, there are several methods that can be used to achieve reconfigurable CP radiation, such as reconfigurable primary radiating elements [1], [2], [7], reconfigurable feeding structures [3]- [6], [10], the reconfigurable slotted ground plane [3], physically rotating the metasurface around the center with respect to the antenna [8], and using the active metasurface [9].…”

This paper presents a polarization switchable circularly polarized (CP) antenna that consists of a compact single-feed crossed dipole loaded with a near-field resonant parasitic (NFRP) element. This antenna is placed above a metallic reflector to enhance its gain and broadside radiation pattern. A meander line with an arrowhead-shaped ending was applied to all arms of the crossed dipole and NFRP elements for compactness. By adjusting the end size of the NFRP element, the antenna was capable of switching its polarization from right-hand circular polarization to left-hand circular polarization and vice versa. The reconfigurability is realized by controlling the ON/OFF states of 8 PIN-diodes, which are inserted into the arrowhead endings of the NFRP element. For the RHCP mode, the antenna yields a |S 11 | <-10 dB bandwidth of 1.465-1.665 GHz and a 3-dB axial ratio (AR) bandwidth of 1.535-1.590 GHz. For the LHCP mode, the antenna yields a |S 11 | <-10 dB bandwidth of 1.50-1.69 GHz and a 3-dB AR bandwidth of 1.545-1.585 GHz. Moreover, in both modes, the antenna yields a good broadside radiation pattern with a gain of > 6.0 dBic and a radiation efficiency of > 70% across its operational bandwidth.

“…Thus, the realization of wideband CP reconfigurable antenna is highly desirable for future wireless communication systems. For instance, in [8] a dipole antenna was positioned above a polarization-rotation artificial magnetic conductor (AMC) structure and integrated with a reconfigurable RF-integrated circuit; it achieved a CPoperation FBW of 15.5%. Another example was reported previously by one of our authors [9]- [10].…”

For future wireless communications, costeffective, low-profile circular polarization (CP) antennas with wide bandwidth and high directivity are highly desirable to increase system capacity and suppress polarization mismatch. In this paper, a wideband circular polarization antenna array integrated with a polarization-independent artificial magnetic conductor (AMC) is reported that meets the demands. First, a wideband CP reconfigurable antenna with a pair of crossbowtie radiators and a metal ground is presented to achieve a fractional bandwidth of 35.9%. By replacing the metal ground with a polarization-independent AMC ground, the antenna profile is reduced from 0.25λ 0 to 0.05λ 0 with only a slight bandwidth decrease. A wideband CP reconfigurable 4-element linear array is achieved using four of those elements. It is low profile (0.05 λ 0), and has a wide operating bandwidth (21.7%), and a high realized gain (13 dBic).

“…In [162], dual-band, dual-sense CP square slot antenna presented. For enhancing the CP operational bandwidth, an artificial magnetic conductor (AMC) or metasurface is successfully applied in a number of designs [164][165][166]. AMC can reduce the antenna physical dimensions and significantly enhances the CP operational bandwidth.…”
