“…The gain in [17,18,20] is lower as compared to the proposed compact design. 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.…”

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.

“…An approximate distance of 0.72λ 0 is kept between the element's centers. A compact 2 × 2 array is described in [21], which consists of square radiating patches that are fed by the SR feed with a truncated ground plane having the C-to-C distance of 0.4λ 0 . However, the design has ARBW from 1.5-2.5 GHz and peak gain of 7.8 dBi.…”

“…In order to achieve these requirements, a traditional series-feed power divider (SFPD) is used in this proposed design. SFPD is a very simple and efficient structure which is popular in circularly polarized antenna design [12][13][14][15][16]. In order to focus on low-cost application, an FR4 Epoxy substrate is selected (er = 4.4, tan δ = 0.02).…”

A low-profile circularly polarized (CP) antenna for a handheld Ultra-High Frequency Radio Frequency Identification (UHF RFID) reader is proposed in this paper. The radiating part on the top substrate is composed of three inverted-F elements rotated 120 • around the center of the structure. A power splitting circuit, placed on the bottom substrate, based on a series transmission line feed delivers equal amplitude to the three IFAs with a sequential 120 • phase shift. Both layers are fabricated on low-cost FR4 material. This design has a disk form factor with a compact size of 35 mm circle radius and an 8.6 mm height. The measurement shows good results with S 11 as lower than −10 dB for the whole band, 3 dB-axial ratio around 110 • (10 MHz of bandwidth), directivity reaching 4.4 dBic, and the total gain of the antenna is 1.9 dBic. In order to validate the proposed antenna performance, a UHF RFID handheld reader is built based on the ThingMagic M6E-Nano module. Different scenarios are investigated to validate the proposed antenna performance in a real environment.

Based on the traditional dielectric microstrip balun, a new-type coupling balun is presented in this study. The front side of this balun is composed of an open stub and two rectangular patches. One end of the rectangular patches is opencircuited, and the other end connects with the dipole. On the back side, there are two other rectangular patches with one end grounded and the other end open-circuited. When using such balun for feeding, one can still get a wide bandwidth, and more importantly, obtain higher port isolation. Compared with the dipole fed by the traditional balun, the maximum/average port isolation of the dipole fed by the new-type one is increased by 10.8 dB/7.9 dB.The new-type balun has a good application prospect in dual-polarized antenna.
