“…The use of annular ring antennas [11][12][13] has also become a very promising applicant for multiband applications because of their simple structure and design flexibility in obtaining miniaturization. For generation of CP waves, many techniques were adopted by researchers which included the perturbation method [14,15], slots [16,17], slits [18], metamaterial [19][20][21], stacking [22,23], etc. Using the above techniques, many designs have been reported by various researchers to obtain triple-band [24,25] and dual-band [26,27] CP antennas.…”

A triple-frequency operated concentric annular ring microstrip antenna which is single fed is presented. The proposed antenna with three concentric annular rings and two symmetrical notches on its outer ring and having a cross slot in its ground surface shows triple band at resonance frequency 1.22760, 1.57542, and 2.18 GHz, respectively. At the first two bands (GPS L2 and GPS L1), circular polarization characteristic is observed and the third band observes linear polarization finding its application in Universal Mobile Telecommunication System (UMTS). The complete dimension of the antenna designed and fabricated is only 51.6 × 51.6 × 1.6 mm3. Experimental results depict the proposed antenna gain of 3.31, 3.55, and 3.50 dBi in three bands, respectively, and closely matches with the theoretical results.

“…If a dual-band dual circular polarization antenna with shared aperture is used, the size and cost of the system could be greatly reduced [3]. In the application of satellite communication [4][5][6], a circular polarization antenna [7,8] receives the incoming wave of arbitrary linear polarization, of which radiated electromagnetic wave could also be received by any linear polarization antenna. Therefore, the relative installation attitudes of the transmitting and receiving antennas are not limited by the torsion angle for the circular polarization antenna.…”

The uplink and downlink of modern satellite communication systems operate on different frequency bands. A novel dual-band dual circular polarization filter antenna with a single port is proposed in this paper. The dual-band characteristic of the antenna is obtained by exciting stacked patches. The antenna supports right-handed circular polarization (RHCP) at lower frequency band and left-handed circular polarization (LHCP) at higher frequency band, respectively. The feeding network is realized with a strip line, and the antenna can be equivalent to a parallel circuit. If the lower frequency patch works, the higher frequency patch presents high impedance, and vice versa. Therefore, the antenna has excellent filtering performance. The measurements of antenna prototype are in good agreement with the simulation results. The impedance bandwidth is 5.80-6.10 GHz and 9.20-10.64 GHz, and the axial ratio (AR) bandwidth is 40 MHz for lower band and 180 MHz for higher band, respectively. Meanwhile, the radiation pattern is stable in the operation frequency bands.

“…Even though the structure proposed above showed an immense enhancement in terms of gain and efficiency, it still lacked compactness in terms of its physical dimensions. In [18], the CP waves were obtained using three N slots on the patch antenna and, later, on circular air hole as EBG structures were drilled on the substrate to enhance its performance and also to achieve compactness. However, it resulted in a complex fabrication process.…”

This study investigates a low-profile circularly polarized (CP) antenna using coplanar waveguide feeding. Rectangular-shaped slots and an inverted L-shaped slit are entrenched into the ground plane to enhance the impedance bandwidth of the antenna. Furthermore, the antenna is implemented with six elliptical electromagnetic band gap structures on its substrate to enhance the −10 dB return loss bandwidth and also to generate CP waves. The experimental and theoretical results closely match each other and indicate that a simple and compact design antenna with dimensions of 0.317λ0 × 0.317λ0 × 0.023λ0(λ0 is the operating wavelength at 4.74 GHz in free space) achieves 36.9% (3.91–5.68 GHz) of the −10 dB return loss bandwidth and 9.98% (4.09–4.52 GHz) of the 3-dB axial ratio bandwidth, thus making it a favorable entrant for radio altimeter and wireless avionics infra-communication systems.
