Protective housings for wireless transmission apparatus and associated methods

A method of comprising:

• forming a housing for an apparatus for portable wireless transmission, the apparatus for portable wireless transmission having an antenna element arranged to resonate at a particular highest resonant operating frequency to send/receive transmissions substantially in a significant radiating direction, the housing comprising:
• a plurality of metal piece areas arranged to, when assembled with the apparatus for the portable wireless transmission, be located over the antenna element in a significant radiating direction in electrical isolation from an electrical ground of the apparatus, wherein the plurality of metal piece areas comprise a plurality of metal pieces arranged with the housing to be substantially electrically isolated from surrounding metal with dimensions having effective lengths of at most about one-tenth of a wavelength for the highest resonating operating frequency of the antenna element, where the plurality of metal piece areas are in a significant radiating direction of the antenna element but allow the antenna element to radiate through the plurality of metal piece areas to provide the housing as a substantially radio transparent housing.

A means for housing for a means for portable wireless transmission, the means for portable wireless transmission having a means for resonating arranged to resonate at a particular highest resonant operating frequency to send/receive transmissions substantially in a significant radiating direction, the means for housing comprising:

• a plurality of metal piece areas arranged to, when assembled with the means for portable wireless transmission, be located over the means for radiating in a significant resonating direction in electrical isolation from an electrical ground, of the means for portable wireless transmission,
• wherein the plurality of metal piece areas comprise a plurality of metal pieces arranged with the means for housing to be substantially electrically isolated from surrounding metal with dimensions having effective lengths of at most one-tenth of the wavelength for the highest resonating operating frequency of the means for resonating, where the plurality of metal piece areas are in a significant radiating direction of the means for resonating but allow the means for resonating to radiate through the plurality of metal piece areas to provide the means for housing as a substantially radio transparent housing.

An apparatus comprising:

• a means for portable wireless transmission, the means for portable wireless transmission having a means for radiating arranged to resonate at a particular highest resonant operating frequency to send/receive transmissions substantially in a significant radiating direction, and a means for housing the means for portable wireless transmission, the means for housing comprising:
• a plurality of metal piece areas arranged to, when assembled with the means for portable wireless transmission, be located over the means for radiating in a significant radiating direction in electrical isolation from an electrical ground of the means for portable wireless transmission,
• wherein the plurality of metal piece areas comprise a plurality of metal pieces arranged with the means for housing to be substantially electrically isolated from surrounding metal with dimensions having effective lengths of at most one-tenth of a wavelength for the highest resonating operating frequency of the means for radiating, where the plurality of metal piece areas are in the significant radiating direction of the means for radiating but allow the means for radiating to radiate through the plurality of metal piece areas to provide the means for housing as a substantially radio transparent housing.
