“…Finally, the antenna proposed in this paper is compared with other reported wideband CP antenna, as shown in Table 1. It can be seen that the reported operating bandwidth in [5–9, 13] is <50%. As reported in [10, 21], better bandwidths are achieved.…”

“…This configuration only achieves gain enhancement in 4.5‐6.5 GHz band. Coplanar spiral as parasitic loading in Reference enhances gain of circularly polarized magnetoelectric dipole antenna at 16.9 GHz up to 11.1 dBi. In Reference , FSS is employed as artificial magnetic conductor (AMC) for gain enhancement of a bow‐tie antenna.…”

In this article, a high‐gain antenna for ultra‐wideband (UWB) communication is presented and experimentally validated. Gain enhancement is achieved by employing a frequency selective surface (FSS) screen as a superstrate. The proposed antenna‐FSS arrangement is less complex and realized on a low‐profile FR‐4 laminate. The antenna comprises a circular radiator that is enclosed in a triangular shaped arrangement of slots along with a narrow feed‐line. Lengths and widths of the different sections along with feed are optimized to achieve an ultra‐wide impedance bandwidth. The employed superstrate is an array of modified square shaped FSS (MS‐FSS). Full wave analysis validates its effectiveness in achieving at least 5 dBi gain enhancement of the UWB antenna while maintaining wideband impedance match. Moreover, the antenna behavior is also analyzed by varying periodicity and the distance between superstrate and the proposed slot antenna. This antenna‐FSS arrangement is a suitable candidate for high‐gain UWB portable devices.

“…A wideband CP magnetoelectric dipole antenna had achieved a 3-dB AR bandwidth of 45.3% from 1.45 GHz to 2.3 GHz [6], but it worked at lower frequency. A magnetoelectric dipole antenna operating at Ku-Band obtained an unstable gain during the band [7]. Therefore, the antenna with good performances in terms of broadband circular polarization, wide AR beamwidth, unidirectional and stable radiation pattern is desirable for 5G communication in MMW band.…”

A millimeter-wave (MMW) windmill-shaped magnetoelectric-dipole antenna with broadband circular polarization and wide axial-ratio (AR) beamwidth is presented. Good circular polarization performances of the proposed antenna are contributed to excellent performances of the magnetoelectric-dipole, the benefit of windmill shape and the sequential feed scheme by a circular microstrip line. Simulation results show that the antenna obtains a wide impedance bandwidth of 58.8% over the band 30～55 GHz, a stable 3-dB AR bandwidth of 30% across the band 34～46 GHz. And the gain is higher than 6 dBic within the AR bandwidth, with the highest gain of 9.2 dBic at 45 GHz. In addition, a unidirectional and stable pattern has also been achieved.
