Dual embedded antenna for an RF data communications device |
摘要 |
An RF antenna system is disclosed having at least one meandering antenna line with an aggregate structure formed to substantially extend in two dimensions, to effectively form a top-loaded monopole antenna. The meandering antenna line includes at least one localized bend for providing a compressed effective antenna length in a compact package. The present antenna can be made as an antenna system having discrete transmit and receive antenna lines, so as to form a dual antenna system. The localized bends on each line electromagnetically couple with the respective bends on the other line, thus increasing electromagnetic coupling efficiency, thereby increasing antenna bandwidth and gain.
