Title (EN) MULTI-FEEDS METAL COVER ANTENNA FOR GAS DETECTION DEVICES
(FR) ANTENNE À COUVERCLE MÉTALLIQUE À ALIMENTATION MULTIPLE POUR DISPOSITIFS DE DÉTECTION DE GAZ
Abstract:
(EN) In an embodiment, an apparatus (e.g., a gas detection device) includes a housing, a printed circuit board (PCB), one or more radio modems with a switching network. The housing includes a conductive cover and the cover plays as an antenna. The PCB may be fixed in the housing and includes a ground plane and a plurality of conductive feeds. Each feed are vertically mounted directly or indirectly on the PCB. When the cover is attached to the housing, each of the feeds electrically contact a respective connection point on the antenna. The switching network is to configure which feed should be connected to the radio modem. A extra grounding resistor is mounted or not to change antenna type to enhance the performance of antenna.
(FR) Selon un mode de réalisation, un appareil (par exemple, un dispositif de détection de gaz) comprend un boîtier, une carte de circuit imprimé, un ou plusieurs modems radio dotés d'un réseau de commutation. Le boîtier comprend un couvercle conducteur et le couvercle joue le rôle d'une antenne. La carte de circuit imprimé peut être fixée dans le boîtier et comprend un plan de sol et une pluralité d'alimentations conductrices. Chaque alimentation est verticalement montée directement ou indirectement sur la carte de circuit imprimé. Lorsque le couvercle est fixé au boîtier, chacune des alimentations entre en contact électrique avec un point de connexion respectif sur l'antenne. Le réseau de commutation est destiné à configurer quelle alimentation doit être connectée au modem radio. Une résistance de mise à la masse supplémentaire est montée ou non pour changer de type d'antenne en vue d'améliorer les performances d'antenne.
