“…CP operation can be obtained only by a dipole with angle [10]. In [11], a rectangular patch instead of a thin dipole can be put to use in order to widen the AR bandwidth. Excited at the edges of the patch, two orthogonal modes can be introduced.…”

Abstract-In this paper, a dual-band circularly polarized (CP) patch antenna with left-hand circular polarization (LHCP) in the lower band and right-hand circular polarization (RHCP) in the higher band is proposed. On the basis of aperture coupled feed, the dual-band circular polarizations are achieved by adopting two rectangular patches with different rotation angles on the front and back of a substrate. A good agreement between the simulated and measured results is obtained. The 10-dB impedance bandwidths and 3 dB Axial Ratio (AR) bandwidths are 18.4% (1.93-2.32 GHz) and 3.2% (2.14-2.21 GHz) in the lower band and 12.4% (2.58-2.92 GHz) and 1.7% (2.84-2.89 GHz) in the higher band, respectively. The proposed antenna with its simple structure, compact size and excellent performance provides a reference for communication system applications.

“…To overcome these shortcomings, many substrate integrated waveguide (SIW) cavitybacked CP slot antennas have been proposed. The following three main radiating configurations of CP SIW cavity-backed slot antennas have been proposed in the literature: compound slots [5][6][7][8][9], annular, triangular or split ring slot [10][11][12][13] and patches, loop or cavity that cover the slots [14][15][16][17][18][19].…”

“…The slot can radiate CP wave when dual orthogonal modes are excited in the SIW cavity resonator. In addition to the compound slots and ring slot etched on the SIW cavity, a rectangular strip rotated by an angle [14], a circular notched patch with stubs [15] or a truncated patch [16] that covers the SIW slot can be used to generate circular polarization. In [17], a rotated elliptical cavities fed by an SIW slot was used to radiate CP waves.…”

Abstract-A circularly polarized (CP) substrate integrated waveguide (SIW) cavity-backed antenna based on dual concentric, orthogonal slot split ring resonators is proposed and experimentally studied. The circularly polarized wave is generated by two split ring-slots etched in the upper metal layer of the SIW cavity resonator. These two slots are excited by a coaxial probe located in the gap of the external slot split ring to radiate the right-handed circularly polarized (RHCP) wave. By rotating the dual split slot ring resonators and the probe by 45 degrees relative to the backed cavity, a better match characteristic and a slightly higher radiation gain are obtained. Because of the concentricity of radiant split ring slots, the beamwidth of the circular polarization is obviously increased. From the experimental results, the impedance bandwidth was 10.8% for the reflection coefficient less than −10 dB, the axial ratio (AR) bandwidth was 1.54% for the AR less than 3 dB, and the RHCP gain was 4.44 dBic. Moreover, the 3-dB axial ratio beamwidth at the centre frequency of 10.40 GHz has been extended to 142 • in the angular range from −78 • to +64 • .

“…The solution in [4], however, exhibited 3.6% 3-dB-Axial-Ratio (AR) bandwidth, which is insufficient for the above-mentioned application. In [5] AR bandwidth was improved replacing the parasitic dipole by a parasitic patch. However cavities were needed to reduce mutual coupling and the overall design becomes much more complex.…”

Institute of Electrical and Electronics Engineers (IEEE)FerrandoThis article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication. Abstract-This paper demonstrates experimentally the improvement in axial ratio performance when a slot is combined with a set of three parasitic dipoles instead of one. The analysis is performed in the context of slotted waveguide arrays and SATCOM applications in Ka band, where a bandwidth specification as wide as 7.5% can be demanded.
