Abstract :
A multi-band internal antenna for mobile phones is realized by means of an elongated flat conductor featuring a closed slot, a ground leg, and a feed leg. A benchmark on a Motorola T192 handset is employed to illustrate the operation of this structure - called folded inverted conformal antenna (FICA) - showing that it provides significantly more radiating bandwidth that a conventional dual band PIFA under the same operating conditions. Because of its favorable performance, FICA is employed in several Motorola handsets in the consumer market.
