DISPOSITIF DE TRANSMISSION BI-BANDE ET ANTENNE POUR CE DISPOSITIF |
摘要 |
<p>The antenna (1) of this system is a microstrip antenna. A rear edge (10) of the body (31) of its patch (6) is provided with a short-circuit (S) by which a quarter-wave type primary resonance can be excited from a connecting line (C1). A slot (17) penetrates the patch from its periphery and separates a body from a tail (33) which remains connected to the body by a passage (32). A secondary resonance mode utilises the body, the passage and the tail. It can be excited from the same connection line at a frequency which is twice that of the primary resonance. The short-circuit can be obtained by components attached to the edge of the substrate of the antenna and can then have inductive, resistive and controlled components. The invention applies in particular to implementing a two-mode mobile radio system using the GSM and DCS standards.</p> |
