“…Likewise, in [6], a compact monopole antenna with a pentagon-shaped patch, symmetrical hook-shaped resonators, and one vertical slot was reported, which was claimed to operate at three frequencies: 3.5 GHz, 5.4 GHz, and 8 GHz. In addition, a defected ground plane-based planar antenna operating at frequencies of 2.47 GHz, 3.55 GHz, and 5.55 GHz for Wi-Fi/WiMAX/WLAN applications was presented in [7]. Utilizing a new coplanar waveguide (CPW) with two slots reported in [8], the lower band operating at 2.453-2.821 GHz, and the higher band running at 5.876-6.892 GHz, might be created.…”

A compact, multiband two-port MIMO antenna is proposed in this paper for various wireless transmission networks, where the overall size of the antenna is only 30 × 20 × 1.6 mm3. The proposed MIMO antenna consists of two radiating patches, each of which comprises a semicircle and a semi-regular hexagon, as well as the surface-etched C-slot and U-slot to tailor the antenna’s return loss characteristics. In proposed antenna, a parasitic branch forms when the ground plane’s meandering branches are symmetrically distributed. On one hand, it can increase the ground plane’s effective area and enhance the antenna’s return loss characteristics. A neutralization line, on the other hand, is generated, thereby limiting the current transmission on the ground plane. A cross-shaped slit in the ground’s center is also employed to further promote isolation between the radiation elements. According to obtained results, the antenna can cover the frequency bands 0.67-7.29 GHz, 8.07-12.11 GHz, 14.07-15.41 GHz, and 16.04-22 GHz (S11<−10 dB). Moreover, an RF isolation larger than 18 dB exists between the two ports. Lastly, in terms of ECC, DG, TARC, CCL, and MEG, the diversity performances are all satisfactory.

“…Although linear polarization wideband antennas [1][2][3][4][5][6][7] are used in various wireless communication systems, circular polarization (CP) antennas have a stronger attraction in some communication systems due to the merits of suppressing multipath interference and reducing polarization misalignment [8][9][10][11]. In addition, with the development of high-rate transmission and processing systems, CP antennas with wide bandwidth, high gains, and low-profle characteristics are also in great demand [12][13][14][15].…”

In this study, a new stacked microstrip slot antenna (MSA) with wideband circular polarization (CP) characteristics is proposed. The antenna consists of a square-loop feed configuration, four parasitic square patches, four parasitic vertical planes, and a square ground plane etched with four parasitic square slots. The corner-cut square-loop can excite a stable 270° phase difference by loading an arc-shaped strip into the square-loop. Square-patches, vertical planes, and square slots as parasitic elements are placed together at the side of the square-loop to stimulate two CP resonant points. Simulation and measurement are performed on the designed antenna prototype to demonstrate the design’s rationality. The measured results depict that the measured impedance bandwidth (IBW) for |S11| < −10 dB is 36.4% (4.65 to 6.70 GHz) and the measured axial ratio bandwidth (ARBW) for AR < 3 dB is 25.1% (5.01 to 6.45 GHz). Compared with other reported stacked CP antennas, the proposed antenna has significant advantages in CP bandwidth, which could occupy the wireless local area network ITS (5.8 GHz), (5.725–5.85 GHz), and WIFI (5.85–5.925 GHz) bands.
