“…Although they are CP, it is such a pity that the metamaterial antennas reported in [6][7][8] have very narrow band. The CP antennas reported in [9][10][11] extend AR bandwidth. However, the antennas based on the microstrip transmission lines have a positively proportional size with the wavelength.…”

“…For array antenna with designed and fixed spaces between the resonators, placing the FSS cells on the antenna substrate will be more difficult and number of them will be limited. To solve this problem in [8] and [9], a superstrate is added which raises the complexity and volume of the antenna structure. In [10] a combination of EBG and PEC structure is introduced for both in band and out band RCS …”

A metamaterial-inspired dual-band antenna with circular polarization is presented in this article. To achieve composite right/lefthand (CRLH) resonance and circularly polarized (CP) properties, three meander lines act as the shunt inductance, and two slots act as series capacitance. The asymmetric CRLH antenna fed by a coplanar waveguide (CPW) realizes zeroth-order resonance and first-order resonance. The dual-band and CP antenna can work in a 3 dB axial-ratio bandwidth as much as 8.5% (2.26-2.46 GHz), and 3.0% (3.90-4.02 GHz). Compared with the recently reported metamaterial antennas, the proposed antenna achieves a smaller size, wider CP bandwidth, and higher gain. V C 2016 Wiley Periodicals, Inc.

“…The AR bandwidth is 16% from 1.38 to 1.64 GHz. In [8] coupled inverted L and U shape strips combined with a slotted ground plane are used for generating CP with an AR bandwidth about 60% from 2 to 3.8 GHz. In [9] a slit in the ground plane and an added stub disturb the ground plane current, forming one of the two required orthogonal components along with the monopole for the CP performance giving an AR bandwidth reaching 44.9% from 4.58 to 7.23 GHz.…”

Abstract-A printed triangular monopole antenna with wideband circular polarization is presented. The wideband circular polarization is achieved by asymmetrical excitation of a triangular ground plane and planar triangular monopole. The combined radiation provides a wide axial-ratio bandwidth spanning from 1.42 to 2.7 GHz (62%). A parametric study of key geometric parameters is given for clear understanding of the radiation mechanism.

“…These include a dipole-like structure with 77% AR bandwidth [7]; a hexagonal slot antenna with 50% AR bandwidth [8]; a radially symmetric aperture with 68% AR bandwidth [9]; an L-shaped slot antenna providing 46.5% AR bandwidth [10] or 32.2% AR bandwidth and 132% impedance bandwidth for more complex geometries [11]. A combination of a slot and a monopole antenna is known to provide from 30% [12] to 60% [13] AR bandwidth, whereas a monopole with a parasitic stub yields 44.9% [14]. An inverted-F antenna in [15] was shown to provide 39.2% AR bandwidth whereas a spiral-inspired compact antenna exhibited 44.5% [16].…”

A compact ultra wideband circularly-polarized slot antenna is proposed with a methodology for automated re-optimization for packaging with proprietary devices. The slot structure employs a dual-feed with an integrated compact ultra wideband phase shifter. The design process involves an advanced optimization algorithm and demonstrates the use of spline curves for generation of circularly polarized signals. These allow easy optimization, while preserving phase coherency across a wide band. The prototyped antenna has a circularly-polarized bandwidth of 54% (from 3.2 GHz -6.1 GHz).
