A novel square ring printed antenna has been suggested for dual‐band circular polarization (CP). The geometry contains a square patch and a square ring structure for dual‐band operation. Circular polarization is achieved using triangular cut at the boundary and right angle bend with inner perturbation. The suggested antenna is excited from the lower layer through electromagnetic (EM) coupling technique. The antenna shows good impedance bandwidths of 90 MHz (2.43‐2.52 GHz) and 800 MHz (5.7‐6.5 GHz, respectively. The antenna shows 3 dB axial ratio bandwidth of 20 MHz at lower band and 120 MHz at upper band with improved gain > 6 dBi. The simulated and measured results are well agreed with each other. The antenna is promising wideband operation at the upper band. This antenna was implemented on fiberglass reinforcement laminated Arlon substrate with dielectric constant (ɛr = 2.55), and the overall physical dimension of 30 × 30 × 3.048 mm3. The designed antenna can be extensibly applicable in WLAN/Wi‐MAX communication. The presented antenna is designed using hyperlynx IE3D and the simulated results are presented.

“…Their precise shape, geometry, size, orientation and arrangement can affect the wave propagation in an unconventional manner [7], creating material properties which are unachievable with conventional materials [8]. Antenna parameters like gain [9][10][11][12][13], effective radiated power [9,10], and bandwidth [10] can be improved using metamaterial properties. Dual-band [1,14], triple-band [15][16][17] and multi-band [18] characteristics can also be achieved using metamaterial.…”

This paper discusses a triple-band microstrip circular antenna using rising sun shaped structure embedded in the substrate of patch antenna. The proposed design is based on the metamaterial property of rising sun shaped structure. The proposed antenna shows good performance at all resonant frequencies. The rising sun structure in substrate makes a major contribution to the first and second operating bands, while it has a minor effect on the third operating band. The proposed antenna is compared with the conventional antenna. This antenna has a high gain at all working frequencies. The simulation results are analyzed and compared with the measured results, which shows that there is a good agreement between them.

“…According to our literature review, most papers focus on the superstrate's effects in linearly polarized antennas. Only a few have reported simultaneous gain and bandwidths enhancement for the CP-MPAs [13][14][15]. In [13,14], the use of FSS superstrates to enhance directivity was proposed, but only gain enhancement has been achieved; neither ARBW nor ZBW improved.…”

In [13,14], the use of FSS superstrates to enhance directivity was proposed, but only gain enhancement has been achieved; neither ARBW nor ZBW improved. In [15], a CP-MPA was integrated with the planar periodic EBG structure to improve both the ZBW and ARBW, to the extent possible, but gain enhancement was not significant.…”

Abstract-This paper proposes a metamaterial reflective surface (MRS) as a superstrate for a single-feed circularly polarized microstrip patch antenna (SFCP-MPA). It illustrates a simultaneous enhancement on antenna gain, impedance bandwidth (ZBW) and axial-ratio bandwidth (ARBW) by adding the MRS atop the SFCP-MPA. The MRS can enhance the ZBW and ARBW by 3.5 and 9.9 times, respectively, compared to the circularly polarized patch source. Moreover, the gain of the CP-MPA with the MRS is 7 dB higher than that of the conventional CP-MPA. The small spacing between the MRS and patch source is another merit in the present design, which is as low as λ • /16, as it results in a low-profile antenna design that well suits modern wireless communications.
