    some suggestion on antenna design inside a metal housing

    Could u give some suggestion or guideline on inside antenna design inside a metal housing of a mobile phone? the antenna i design is monopole or PIFA . Do you think which is better for performance ? thans in advance.

    Re: some suggestion on antenna design inside a metal housing

    PIFA is also a Monopole antenna.
    Is derivated from Inverted-F, and Inverted F is derivated from Inverted-L, and Inverted-L is a bent Monopole antenna over a ground plane.
    Due to its near-field current distribution PIFA is more suitable for metal housing.

    some suggestion on antenna design inside a metal housing

    by metal housing you mean the antenna is completed
    or parcially sorrounded by metal? This is one of
    main recommendation about antennas: does not
    put them close or inside metals because will not
    work. In most of the cases, however, is inevitable
    that the antenna being modified by the near metals.
    In that case the whole package is the antenna. Any
    dielectric(plastic) or metal will modify the impedance
    and resonance frequency of the antenna.
