A miniature antenna working in European, Asian and Australian ISM sub-GHz bands is presented for IoT application. The antenna was first designed and simulated to achieve a low quality factor, i.e. having good matching at 896MHz. A second-order …
A novel wideband rectangular dielectric resonator antenna (RDRA) is proposed in this paper. An equivalent air-dielectric DRs blocs are introduced inside the resonator to enhance the structure's bandwidth. The hybrid structure is excited by a simple …
In this paper an antenna array for imaging applications is presented. A two-step design process is used. In the first step, a wideband printed monopole antenna to be employed as the array element is synthesized by means of a Particle Swarm …
