ABSTRACT
A radiotelephone/pager unit (100) includes a housing
enclosing (102, 104) radiotelephone circuitry (224) coupled
to a radiotelephone antenna (108) operable at radiotelephone
frequencies and pager circuitry (218) coupled to a pager
antenna (212) operable at pager frequencies. The radiotelephone antenna (108) is located outside the housing (102,
104) in a conventional manner. The pager antenna (212) is
located outside the housing (102, 104) and concealed under
or integrally formed with a hand grip (122), a display lens
(402), an escutcheon (502), a keypad (110), or a cap (601)
such that the pager antenna's presence is unnoticeable to a
user. The pager antenna (212) forms a loop antenna substantially surrounding a user interface element such as a
display (112), a keypad (110), an earpiece (114) or volume
control buttons (118, 120) to minimize space.
