The invention relates to a radio antenna in the form of a transmitting antenna or a receiving antenna, and a mobile radio system. According to the invention, the radio antenna (MS/A, BTS-A) is a flat top antenna and comprises a carrier element (1) consisting of electrically insulating material; a coating (2) which is applied to the same, and two interspaced coating feeders (3, 4) comprising an electrical connection to the coating (2) situated in-between. Said coating is produced from a coating material which consists of given amounts of determined materials such as a bonding agent, an insulating agent, a dispersing agent and distilled water. Electromagnetic waves can be emitted or received by means of the coating (2), advantageously offering a high frequency selectivity in conjunction with an omnidirectional characteristic.

L'invention concerne une antenne radio utilisée comme antenne émettrice ou antenne réceptrice, ainsi qu'un système radiomobile. L'invention est caractérisée en ce que l'antenne radio (MS-A, BTS-A) est une antenne plate et comprend un élément support (1) en un matériau électriquement isolant, un revêtement (2) appliqué sur celui-ci, et deux amenées au revêtement (3, 4), à distance entre elles, présentant une connexion électrique au revêtement (2) placé à distance intermédiaire. Le revêtement est fabriqué en un matériau de revêtement constitué, en des proportions données, de matières déterminées renfermant un liant, un isolant, un agent dispersant et de l'eau distillée. Le revêtement (2) permet l'émission ou la réception d'ondes électromagnétiques, tout en offrant en même temps, avantageusement, la possibilité d'obtenir une haute sélectivité de fréquence, conjointement avec une caractéristique omnidirectionnelle.
