Description
Tran and co-authors design a compact antenna with round-polarized MIMO output. Most MIMO arrays feed one element per port, which grows size. Their design feeds dual-polarized elements through hybrid couplers. Two elements thus serve four ports in total. Shared firing of both elements lifts gain as well.
A built prototype matched the design in bench tests. The unit spans about 1 point 41 by 1 point 06 wavelengths in face size. Its working band ran 9 point 5 percent, from 5 point 0 to 5 point 5 GHz. Port isolation beat 10 dB, and gain ran 7 point 8 to 8 point 8 dBi. Targets include Wi-Fi 6, C-band radar, and satellite IoT links.
