A novel miniaturised wideband antenna based on dual‐layer metasurface (MS) is proposed in this study. It is composed of three metallic and two substrate layers. The top metallic layer is the MS whose unit is a square patch etched four interlaced quarter arc‐shaped slots (PQAS). The middle metallic layer is a circular ring patch. The bottom metallic layer is the MS formed by the square metal ring (SMR). The top MS with PQAS and the bottom MS with SMR are combined which serve as a radiator and ground plane of the antenna directly, not a reflector. Thus, avoiding air layer, a low profile of 0.014 λ0 (λ0 is the guided wavelength at 2.57 GHz) is realised. Meanwhile, the impedance bandwidth and gain of the antenna are improved. The measured results show that the −10‐dB impedance bandwidth of the proposed MS antenna is from 2.57 to 4.12 GHz (the relative bandwidth is 46.3%). Furthermore, the maximum gain reaches 4.17 dBi.

“…In [13], another compact‐wearable antenna has been designed with an \DIFdel{electro‐magnetic bandgap (}EBG\DIFdel{)} structure where the metallic layer is replaced by a conductive textile sheet to improve the comfort level. For enhancing the gain, FSS [14] and metasurface [15] has also been used as superstrate over the wearable antenna.…”

“…Due to the avalanche of 5G handset [1]- [6], wearable [7]- [13], and implant wireless devices [14]- [19], the needs for antenna miniaturization are increasingly extended. However, the reducing dimension of antenna causes the restriction on its performance including bandwidth, radiation efficiency, and especially for gain [20]- [22].…”

The scenario of using a spatially distributed antenna for miniaturized applications is presented in this work. A model of lens antenna with a low profile, compact, and high focusing superstrate, which exquisitely combines the conventional lens and resonant cavity superstrates, is proposed. Based on this model, the parasitic lens superstrate is introduced with high performance and simple configuration. The parasitic lens includes a low dielectric substrate and high resonant parasitic elements. By manipulating the surface currents of parasitic elements concentrating at center region of superstrate, the focusing effect is obtained. A prototype of the parasitic lens antenna was implemented with the source and parasitic superstrate's lateral dimensions of 0.5λ 0 × 0.5λ 0 and λ 0 × λ 0 , respectively, and the profile of 0.54λ 0. The peak gain is 10 dBi, corresponding to the enhancement of 5 dB. The measured results perspicuously demonstrate the efficiency of the compact parasitic lens.
