Abstract: Une électrode de radiation parasite (13) et une électrode de radiation excitée (4) sont formées selon un certain intervalle sur la surface d'une base diélectrique (2). Un matériau (8) permettant l'ajustement de la permittivité est prévu à une certaine distance (S) entre l'électrode de radiation parasite (3) et l'électrode de radiation excitée (4) où la capacité est créée. Le matériau (8) pour l'ajustement de la permittivité présente une permittivité inférieure à celle de la base diélectrique (2), de manière que la permittivité entre l'électrode de radiation parasite (3) et l'électrode de radiation excitée (4) soit inférieure à celle de la base diélectrique (2), le couplage capacitif entre l'électrode de radiation parasite (3) et l'électrode de radiation excitée (4) étant ainsi réduit. Ainsi, l'interaction en résonance entre l'électrode de radiation parasite (3) et l'électrode de radiation excitée (4) diminue, ce qui permet l'amélioration de l'efficacité de l'antenne sans qu'aucune mesure ne soit prise, telle que l'augmentation de l'intervalle (S) entre l'électrode de radiation parasite (3) et l'électrode de radiation excitée (4) et la réduction de la permittivité de la base diélectrique (2), mesures pouvant empêcher la miniaturisation d'une antenne montée en surface (1).

The wick is formed from a hydrophobic material in order to repel flush water so that flush water does not travel down the side of the wick and dilute the liquid in the reservoir with flush water. In another aspect, the suspension means and/or the entire device is not visible from above the rim of the toilet bowl when the dispensing device is installed on the rim.
