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 …
In this paper, the impact of the ground plane reduction imposed by modern wireless terminals on the antenna performance is evaluated. Numerical results in terms of antenna efficiency andQ-factor are discussed for two different antenna geometries.
