Dans ce travail, nous comparons deux différentes topologies d'antennes intégrées dans un deux différentes topologies d'antennes intégrées dans un dispositif IoT miniature fonctionnant de 900 MHz:Antenne F inversée (IFA) et antenne à Résonnateur Diélectrique (ARD). Ce type d'appareil portatif peut être fortement affecté par l'effet du corps...

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 Microstrip feed line, adapted with a stub at the end of the line. The resonant modes of the...

In this work, we compare two different antenna topologies integrated in a miniature IoT device working at 900 MHz: Inverted F Antenna (IFA) and Dielectric Resonator Antenna (DRA). This type of handheld device can be strongly impacted by human body effect, consequently we study theradiation performance of the two structures close to a human...

Direct Microstrip line, Microstrip slot-coupled feed and hybrid coupler techniques are investigated for Cylindrical Dielectric Resonator Antenna (CDRA). The Dielectric resonator has a dielectric constant of 30, and etched on Arlan dielectric substrate having a relative permittivity of 3.58 and dimensions of 150 x 150 mm2. The structures are...

This article introduces an innovative approach to significantly broaden the bandwidth of Cylindrical Dielectric Resonators. A four-element Camembert-Shaped Cylindrical Dielectric Resonator Antenna (CDRA) is presented, using an air gap separating the resonators to enhance the antenna bandwidth. The radiators, i.e., the DRA blocks, are made of...
