“…In recent years, the fast development of multi-system integration technology has initialized growing interest in dual-band circularly polarized antenna. Some dual-band circularly polarized antennas have been investigated and presented, such as the patch [1,2] or the slot [3,4]. For example, an S-shaped slotted patch antenna with dual-band CP has been presented for GPS applications [1].…”

The asymmetrical S-shaped slot, which acts as a perturbation of the patch, excites the two orthogonal field components with a 90 • phase-shift for the CP operation at the lower frequency band.…”

Abstract-This paper presents a microstrip wideband antenna and its utilization in integration of multiple wireless communication systems. A simple fork-like strip antenna, fed by a coplanar-waveguide (CPW) transmission line, is designed to excite a right-hand circularly polarized wave at 1.57 GHz. A rectangular patch is added at the end of one prong to enhance the circular polarization performance. By modifying the geometry of the ground plane, a left-hand circularly polarized wave is excited at 2.33 GHz, and the wideband frequency response is derived. To reduce the lower resonant frequency, a stub is added at the left side of the ground plane. The measured impedance bandwidth of reflection coefficients (S 11 ) < −10 dB ranges from 1.49 to 2.92 GHz, which satisfies the system bandwidths of most of commercial wireless communication systems. The 3-dB axial-ratio bandwidths are approximately 40 MHz at the lower band (1.57 GHz) and 290 MHz at the upper band (2.33 GHz).

“…For these purposes, dual-band circularly-polarized small antennas are required. Some printed dual-band circularly-polarized antennas have been proposed [3][4][5][6][7][8]. However, most of them radiate a circularly-polarized wave to the bidirection (front and back sides).…”

Abstract-A dual-band circularly-polarized microstrip antenna is proposed, and the antenna for GPS is designed. The radiation characteristics of the dual-band circular polarization are achieved by installing one pair of L-shaped slits at all edges of the square patch. The impedance matching in the dual band is tuned by an L-probe feed. The proposed antenna is effective and useful in the design for dual-band circularly-polarized operation.

“…And recently stacked microstrip antennas have been developed to obtain dualband or tri-band radiation. Some dual-band CP stacked microstrip patch antennas were achieved, like using an aperture couple feed [4] [5], by two different types of stacked patched [6], and by carving an asymmetric S-shaped slot [7]. In [8], a stacked patch technique with a high permittivity dielectric material is used to achieve a compact triple band antenna design.…”

Abstract-This paper proposes a novel stacked tri-band circularly polarized antenna which has three independent ports. To obtain tri-band operation, a stacked three layers of microstrip antenna working at different frequency is presented. Each of them is fed by dual feed probes. The simulated results show that the antenna can cover Compass Navigation Satellite System CNSS B3 1.268 GHz, L band 1.615 GHz and S band 2.49 GHz. The proposed antenna has achieved a bandwidth of 3.1%, 6.8% and 2.3% at each band, respectively. It exhibits small axial ratio under 3dB in three bands for the CNSS applications. Details of the proposed antenna design and results for the obtained tri-band circularly polarized performances are presented and discussed.
