Abstract
A broadband antenna comprises a driven element and a parasitic element resonant at different frequencies so that the antenna had a bandwidth encompassing both resonant frequencies. A further driven element, resonant at a third frequency, may be added so that the antenna is also usable in a different separate band.
Claims13
An antenna comprising a driven element, resonant at a first frequency and a parasitic element, wherein the parasitic element is resonant at a second different frequency and said resonant frequencies are such that the antenna has an operational band of usable frequencies encompassing said first and second frequencies.
An antenna comprising a substantially planar substrate, a first driven element, resonant at a first frequency, a second driven element, resonant at a second, lower frequency, a parasitic element associated with the first driven element, a common ground terminal for connecting all of the elements to an external ground and a single feed terminal for connection to an external signal feed, wherein said elements and terminals comprise a conductive pattern on the substrate.
A mobile phone including a casing and an antenna according to any preceding claim mounted within said casing.
An antenna substantially as hereinbefore described.
