ANTENNE A COUCHE CONDUCTRICE ET DISPOSITIF DE TRANSMISSION BI-BANDE INCLUANT CETTE ANTENNE |
摘要 |
<p>The antenna of said transmitter is a microstrip antenna. A rear edge of its patch is provided with a short circuit by means of which a quarter-wave primary resonance can be excited by a coplanar line formed by two coupling slots in an area. Separator slots separate said area from another area in which a secondary resonance can be established at twice the frequency of the primary resonance from a slotted line extending one slot of the coplanar line. The invention applies in particular to the production of a dual-mode mobile telephone to the GSM and DCS standards.</p> |
