“…The ARBW of the design in [18] is 7.6%, which is just greater by 0.66% than the ARBW of the proposed design. Unlikely, the ARBW in [19] is very low that is 1.3%. In all of the above literature, the designs have higher gain at the expense of the size.…”

“…Unlikely, the size of the [21] is comparatively smaller as compared to the proposed work, but it results in a very low gain. The gain of 13.5 dBic in [19] is higher because of the larger distance between the centers of the elements. Similarly, the gain of 14.25 dBic is achieved in [22] by using the air gap in multiple layers.…”

“…However, the parasitic rectangular patches are used to increase the bandwidth performance, but increase the footprint. Reference [19] presented a Ka-band 2 × 2 array based on a simple rectangular microstrip patch with truncated corners fed by SR feed. The element's centers are kept at a distance of 1.72λ 0 , resulting ARBW of 28.45 to over 30 GHz.…”

In this article, a high gain and compact 4 × 4 circularly polarized microstrip patch antenna array is reported for the data transmission of the next-generation small satellite. The radiating element of the circularly polarized antenna array is realized by the conventional model of the patch with truncated corners. A compact two-stage sequential rotational phase feeding is adopted that broadens the operating bandwidth of the 4 × 4 array. A small stub is embedded in the sequential rotational feed, which results in better performance in terms of the S-parameters and sequential phases at the output ports than sequential rotational feed without open stub. A prototype of the array is fabricated and measured. Fulfilling the application requirements of the next-generation small satellites, the array has the left-handed circularly polarized gain of more than 12 dBic with the axial ratio level below 1.5 dB in the ±10∘ angular space with respect to the broadside direction for the whole bandwidth from 8.05 GHz to 8.25 GHz. Moreover, the left-handed circularly polarized gain varies from 15 to 15.5 dBic in the desired band. The radiation patterns are measured; both the co- and X-pol are validated.

“…When the SR techniques are used, the radiated polarization type of the element cannot be considered and the overall bandwidth performances of CP antenna arrays can be significantly improved. Until now, many CP antenna arrays using SR feed networks have been reported [4][5][6][7][8][9][10]. In [4], CP antenna array with wide axial ratio (AR) bandwidth was obtained by rotating linearly polarized elements sequentially.…”

“…However, the defected ground structure leads to back radiation and difficult encapsulation. In [9], a Ka-band CP microstrip antenna array with a high-gain level was designed. The serial feed SR technique improved the bandwidth, radiation pattern, and polarization purity over a wider frequency band compared with the coplanar corporate feed network.…”

A broadband high‐gain circularly polarized (CP) microstrip antenna operating in X band is proposed. The circular polarization property is achieved by rotating four narrow band linearly polarized (LP) microstrip patch elements in sequence. Since the conventional series‐parallel feed network is not conducive to the miniaturization of the array, a corresponding simplified feed network is designed to realize the four‐way equal power division and sequential 90° phase shift. With this feed network, the impedance bandwidth (IBW) of the CP array is greatly improved compared with that of the LP element, while maintaining a miniaturized size. Then, parasitic patches are introduced to enhance the axial ratio bandwidth (ARBW). A prototype of this antenna is fabricated and tested. The size of proposed antenna is 0.93λ0 × 0.93λ0 × 0.017λ0 (λ0 denotes the space wavelength corresponding to the center frequency 10.4 GHz). The measured 10‐dB IBW and 3‐dB ARBW are 13.6% (9.8‐11.23 GHz), 11.2% (9.9‐11.07 GHz) respectively, and peak gain in the overlapping band is 9.8 dBi.
