A novel analytical method based on the cavity mode theory to design a metasurface (MS) is proposed in this study. We carefully analyzed the phase and amplitude characteristics of the incident wave and transmitted wave, and successfully designed a circular polarization conversion MS by introducing a cutting structure with wider operation bandwidth and higher radiation direction gain compared with that of the original MS. For the measurements, a microstrip antenna operating at 2.4 GHz was used as the source antenna to verify the designed MS. The simulation and measurement results agree well with each other.

“…The filtering antennas using metasurface or metamaterial show high‐gain and filtering characteristics, however, it has also the disadvantages of large size due to air gap between the radiator and the metamaterial/metasurface . The proposed antenna in Reference has a good filtering characteristics but its bandwidth is wider than the frequency band proposed for the 5G band. This may cause the interference from other neighboring licensed bands.…”

“…Some antennas with the stacked patches achieve filtering performance, but they have a large physical size which may limit its integration with the modern 5G devices. On the other hand, metasurfaces are widely used in antenna design for the enhancement of gain, increasing bandwidth, polarization conversion, and filtering response . The filtering antennas using metasurface or metamaterial show high‐gain and filtering characteristics, however, it has also the disadvantages of large size due to air gap between the radiator and the metamaterial/metasurface .…”

This article presents a low‐profile filtering antenna based on nonuniform metasurface for fifth generation (5G) systems at 3.5 GHz. A crossed stub, slotted ground, shorting via, and the nonuniform metasurface is used to achieve high gain and filtering response in lower and upper stopbands. The antenna and the metasurface are printed on Rogers RO4003C (εr = 3.38, tan δ = 0.0027) and Taconic TLX‐9 (εr = 2.5, tan δ = 0.0019), respectively. Measured results show that the antenna has an impedance bandwidth of 3.24 to 3.8 GHz (15.91%) below −10 dB with a stable gain having a maximum value of 10.43 dBi and good radiation patterns. Moreover, this antenna passband satisfies the typical bandwidth required for the global 5G spectrum at the 3.5 GHz band. The gain drops significantly and the S11 goes up to 0 dB outside the passband. Due to the excellent filtering characteristics, the proposed antenna is a good candidate for 5G applications.
