“…To realize a unidirectional pattern and reducing the antenna profile, using the AMC structure as a reflector has been reported in 3,13,21 . The in‐phase reflection property of AMC can break the λ/4 limit between the antenna and the floor, thus reducing the antenna profile 3,9 . However, it is still a challenging task to design and applies the AMC structure into a CP antenna with ultrawide CP bandwidth, unidirectional radiation, and wideband axial beam radiation characteristics.…”

“…As the circularly polarized (CP) wave excited by the CP antenna has the advantages of reducing multipath interferences and immune to faraday rotation in the ionosphere, there is a continuous need to design a broadband CP antenna that can cover multiple communication systems. [1][2][3][4][5][6][7][8][9][10] Many kinds of broadband CP antennas have been reported, such as the substrate integrated waveguide slot antenna, 4 dipole antenna, 5 printed monopole antenna, 8 and helical antenna. 10 Even though a CP antenna with a single radiator element has the advantage of small size, it usually cannot achieve a good axial beam radiation (main beam at boresight direction +z = 0 ) across the entire CP bandwidth.…”

A broadband circularly polarized (CP) slot antenna unit that is composed of a sector‐shaped radiator and an irregular pentagon slot ground plane is initially investigated. The CP characteristics are realized based on unbalanced feeding and loading of irregular slot structure. To increase the gain and yield ultrawideband operation, a 2 × 2 antenna array with a sequential rotational feeding method is introduced. To further reduce the total profile of the proposed antenna array to 0.15λ0, an artificial magnetic conductor array reflector is loaded between the antenna array and the feeding network. The measured 10‐dB impedance bandwidth of the proposed antenna array was 82.6% (8.31–20.0 GHz), and its corresponding CP bandwidth was 65.4% (8.61–16.98 GHz), and the radiation efficiency of the antenna is also higher than 80%. Besides exhibiting very good axial beams across the wide CP bandwidth, a peak gain of up to 11.1 dBic is also achieved. Thus, it is suitable for X‐band and Ku‐band satellite communication applications.

In this paper, a novel wideband circularly polarized (CP) array antenna is proposed. The array element is composed of four driven patches, four parasitic patches, and a loop feeding structure. On the basis of the array element structure, 1 × 2 and 2 × 2 arrays with shared patches are formed separately. Compared with the traditional structure, the volume of the 1 × 2 array antenna which only shares the patches in the x direction is reduced by 15%, and the volume of the 2 × 2 array antenna which shares the patches in the x and y directions is further reduced by 28%. The cleverness of this method is that it can keep the impedance bandwidth almost unchanged. To validate the simulated results, antenna prototypes are fabricated and measured. The results of the measurements demonstrate that the impedance bandwidths of the 1 × 2 and 2 × 2 array antennas are 27.2% (5.40–7.10 GHz) and 35.7% (5.22–7.49 GHz), respectively, and the 3 dB axial ratio (AR) bandwidths are 22.7% (5.31–6.67 GHz) and 25.4% (5.47–7.06 GHz), respectively. In addition, the measured data show that the 1 × 2 array exhibits a peak gain of 11.1 dBic, and the 2 × 2 array achieves a peak gain of 12.6 dBic. Both of them achieve a flat gain with a maximum ripple of less than 1.3 dB over the whole operating band.
