“…In [10,14], it was found that the phase of circular polarization ϕ is linearly dependent on the dipole angle while it is independent of the slot angle, length and offset which only determine the impedance matching.…”

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.

“…Two orthogonal field components are achieved by tilting the parasitic dipole a certain angle α with respect to the slot, while the phase quadrature is assured through the distance between slot and dipole. This technique has been successfully proved experimentally in a slotted waveguide array in [4]. This approach has advantages such as low profile, fabrication simplicity, good polarization purity and ease of design.…”

“…This approach has advantages such as low profile, fabrication simplicity, good polarization purity and ease of design. 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.…”

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.

“…To generate circular polarization, a rotated dipole array (as shown in Fig. 2(b)) which serves as a linear-to-circular polarization converter is added in front of the LP SCA antenna [12]. The number of the dipoles is the same as that of slots and each dipole locates above corresponding slot and is rotated by an angle of α from y-axis.…”

In this letter, a single-fed low-profile high-gain circularly polarized slotted cavity antenna using a high-order cavity mode, i.e. TE 440 mode, is proposed. The proposed antenna has a simple structure which consists of a radiating linearly polarized slotted cavity antenna and a linear-to-circular polarization converter. An antenna prototype operating at WLAN 5.8 GHz band fabricated with low-cost standard printed circuit board (PCB) process is exemplified to validate the proposed concept. Measured results compared to their simulated counterparts are presented, and a good agreement between simulation and measurement is obtained.
