“…It is also achieved with single feeding techniques by using truncated corner-/slit-/slot techniques. The broadband circular polarization is achieved by using reactive impedance surface to the truncated corner-/slit-/slotloaded patches, [1][2][3] L-shaped structures in monopole antennas, 4,5 L-shaped structures along with dielectric resonator antenna in Qian and Xie 6 and bow tie dipole antenna with reflector in Xu et al 7 To improve the antenna gain of planar antennas in a broadside direction, a periodic array of patches are used as a metasurface above the radiating element.…”

The circularly polarized antenna with high gain and broad bandwidth in single layer substrate is realized with mushroom‐loaded nonuniform square patches and aperture CPW feed for 5 GHz Wi‐Fi applications. An array of nonuniform square patches are excited by using a uniform aperture CPW feed. Moreover, the mushrooms are connected between the patches and the ground plane to reduce the spurious radiations on the patch. Mushrooms are moved in the diagonal direction of patches to generate circular polarization. The dimensions of the middle patches are increased and the mushrooms of the middle patches are moved further in the diagonal direction to enhance the impedance bandwidth (IBW) and 3 dB axial ratio bandwidth (ARBW). An array of mushroom‐loaded nonuniform square patches with aperture CPW feed has achieved an IBW of 54.2% (4.76–8.3 GHz), an ARBW of 14.3% (5.49–6.29 GHz) and the peak gain of 9.5–9.9 dBi over 5 GHz Wi‐Fi band.

“…Nowadays, one of the effective ways to solve the demand of mass data communication is designing broadband CP antennas, and it can resist interference, multipath and polarization mismatch. [1][2][3] For planar circularly polarized antenna, many applications often need its high directivity or high gain, and its low-profile is always limited by low directivity. CP monopole antenna design is also very easy to operate in realizing the low-profile and miniaturization function of the antenna.…”

This article presented a wideband circularly polarization (CP) monopole antenna with elliptic ring slot patch using characteristic mode analysis (CMA). By analyzing the characteristic modes of elliptical patch and elliptical ring patch in turn, it is found that the elliptical ring slot patch can meet the phase requirement of CP. Then, the parasitic elliptical ring slot patch is used to broaden the impedance bandwidth and polarization bandwidth of the antenna.The broadband is obtained by the modal significance (MS) analysis, and the CP is realized by analyzing the characteristic current of two modes are orthogonal and the characteristic angle (CA) close to 90 . The proposed antenna was fabricated and measured with the size of 0.59λ 0 Â 0.59λ 0 Â 0.02λ 0 . The measured 3-dB axial ratio (AR) band is from 5.3 to 9.4 GHz (55.8%), and the À10 dB impedance band is from 4.5 to 9.7 GHz (73.2%).
