Receiver having concealed external antenna

A combination radiotelephone/pager unit comprising:

• radiotelephone and pager circuitry;
• a housing substantially enclosing the radiotelephone and pager circuitry;
• an electromagnetic shield, disposed in the housing and at least partially covering at least one of the radiotelephone and pager circuitry, formed of an electrically conductive, electromagnetic wave-absorbing material for absorbing electromagnetic energy radiated by or towards the at least one of the radiotelephone and pager circuitry;
• a radiotelephone antenna coupled to the radiotelephone circuitry;
• a pager antenna coupled to the pager circuitry, carried on an outside, nonconductive surface of the housing and disposed outside the electomagnetic shield;
• and
• a substantially planar and detachable cover, attached to the outside, nonconductive surface of the housing, for concealing the pager antenna between the cover and the outside, nonconductive surface of the housing such that the pager antenna is unnoticeable to a user of the unit.

A receiver including a user interface comprising:

• a housing;
• receiver circuitry disposed in the housing;
• and
• an antenna coupled to the receiver circuitry;
• wherein the antenna forms a loop surrounding at least a portion of the user interface and is disposed between an outside surface of the housing and the at least a portion of the user interface.

A receiver comprising:

• receiver circuitry;
• a housing substantially enclosing the receiver circuitry;
• an electromagnetic shield, disposed in the housing and at least partially covering the receiver circuitry, formed of an electrically conductive, electromagnetic wave-absorbing material for absorbing electromagnetic energy radiated by or towards the receiver circuitry;
• an antenna coupled to the receiver circuitry, carried on an outside, nonconductive surface of the housing and disposed outside the electomagnetic shield;
• and
• a substantially planar and detachable cover, attached to the outside, nonconductive surface of the housing, for concealing the antenna between the cover and the outside, nonconductive surface of the housing such that the antenna is unnoticeable to a user of the receiver.
