    Wahaj Abbas Awan1, Do Min Choi1, Niamat Hussain1, Issa Elfergani2,3, Seong Gyoon Park4, Nam Kim1,*

    CMC-Computers, Materials & Continua, Vol.73, No.3, pp. 6169-6180, 2022, DOI:10.32604/cmc.2022.026343

    Abstract This paper presents the design of wideband and high gain Frequency Selective Surface (FSS) loaded antenna for ultra-wideband (UWB) wireless applications requiring high-gain. The antenna consists of a monopole and an FSS reflector. Initially, a conventional rectangular monopole antenna is modified using slot and stub to achieve wide operational bandwidth and size reduction. This modified antenna shows 50% miniaturization compared to a primary rectangular monopole, having a wide impedance bandwidth of 3.6–11.8 GHz. Afterward, an FSS is constructed by the combination of circular and square ring structures. The FSS array consisting of 8 × 8-unit cells are integrated with the antenna as… More >

    CMC-Computers, Materials & Continua, Vol.70, No.1, pp. 1419-1436, 2022, DOI:10.32604/cmc.2022.019741

    Abstract In this paper, a high gain and directional coplanar waveguide (CPW)-fed ultra-wideband (UWB) planar antenna with a new frequency selective surface (FSS) unit cells design is proposed for UWB applications. The proposed UWB antenna was designed based on the Mercedes artistic-shaped planar (MAP) antenna. The antenna consisted of a circular ring embedded with three straight legs for antenna impedance bandwidth improvement. The modelled FSS used the integration of a two parallel conductive metallic patch with a circular loop structure. The FSS provided a UWB stopband filter response covering a bandwidth of 10.5 GHz, for frequencies from 2.2 to 12.7 GHz.… More >
