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.

BACKGROUND OF THE INVENTION
Paging systems And radiotelephone systems, such as
cellular radiotelephone systems, have gained widespread
acceptance over the years. The trend in growth of these
systems has continued to be positive, especially as the
technology has evolved to enable reductions in the size and
weight of pagers and portable cellular radiotelephones.
Many of the users of portable cellular radiotelephones have
continued to be users of pagers, which has resulted in the
requirement that those users carry not only a portable
cellular radiotelephone but also a pager. With the trend in
technology continuing to enable further miniaturization of
both portable cellular radiotelephones and pagers, it is now
possible to combine both elements into a single portable
unit. Such a combination, however, has been shown to create
problems not previously encountered when both the portable
cellular radiotelephone and the pager were separate units.
The portable radiotelephone typically has an antenna
outside an at least partially shielded housing for transmitting
and receiving radio frequency signals at radiotelephone
frequencies. The pager typically has an antenna inside an
unshielded housing for receiving radio frequency signals
pager frequencies. When a pager is combined with the
portable radiotelephone into a single unit, the location of the
radiotelephone antenna and the pager antenna is considered.
The most likely place for the radiotelephone's antenna is
at its conventional location outside the radiotelephone housing. Consideration is given to the location of the pager's
antenna both inside and outside the radiotelephone's housing. The pager antenna can not be located inside the radiotelephone's shielded housing portion, since the shielded
housing would prevent the pager's antenna from receiving
paging signals. The pager's antenna can be located inside an
unshielded portion of the radiotelephone's housing,
however. the compactness of a single unit makes unshielded
locations rare. Furthermore, remotely locating the pager's
antenna from the pager circuitry to reach an unshielded
location produces inefficiencies in the pager's antenna. The
pager antenna can be located outside the radiotelephone's
housing. However, locating the pager antenna in addition to
the radiotelephone antenna outside the radiotelephone's
housing would change the external appearance of the radiotelephone and possibly increase its size.
Thus, there is a need for a beneficial location for the pager
antenna without compromising the antenna's performance
or the appearance and size of the unit.

FIG. 1 is a perspective view of a radiotelephone/pager
unit constructed in accordance with the present invention.
FIG. 2 is an exploded view of the radiotelephone/pager
unit of FIG. 1 showing a first location of a pager antenna. 65
FIG. 3 is a perspective view of the pager antenna of FIG.
2 integrally formed with switch contacts.

Referring now to FIG. 1, there is shown a perspective
view of a combination radiotelephone/pager unit 100 constructed in accordance with the present invention. The unit
100 generally includes: a front housing 102, a back housing
104, a battery 106, a radiotelephone antenna 108, a keypad
110, a display 112, an earpiece 114, a microphone 116,
volume control buttons 118 and 120, a hand grip 122 and an
alert 124.
The external appearance and functionality of the unit's
radiotelephone portion is similar to that of a conventional
portable cellular radiotelephone, model number 1293A,
manufactured and available from Motorola, Inc. The functionality of the unit's pager portion is similar to that of a
conventional pager. named "Bravo", also manufactured and
available from Motorola, Inc. The user interface such as the
keypad 110, volume control buttons 118 and 120. display
112 and alert 124 are commonly used by both the radiotelephone portion and the pager portion of the unit 100.
The unit 100 uses the radiotelephone antenna 108 to
conventionally transmit and receive radiotelephone signals
at radiotelephone frequencies. The unit 100 uses a pager
antenna (not shown in FIG. 1) to conventionally received
pager signals at pager frequencies.
A unique element of the present invention which will be
shown and discussed later in the preferred embodiments of
the present invention is that the pager antenna is located
outside the radiotelephone's housing and yet not noticeable
to a user. The following preferred embodiments of the
present invention will show the pager's antenna being
concealed by covers forming conventional radiotelephone
parts including but not limited to the hand grip 122. the
keypad 110, a lens of the display 112 and also by a cap
secured to the front housing 102. Benefits of concealing the
pager antenna with these covers outside the radiotelephone's
housing include maintaining the radiotelephone's external
appearance, having the pager's antenna outside any shielded
portion of the radiotelephone's housing and keeping the
pager's antenna close to the pager's circuitry. The following
preferred embodiments of the present invention will also
show the pager's antenna forming a loop substantially
surrounding the tactile, visual and acoustic user interface of
the unit 100 including but not limited to the volume control
buttons 118 and 120, the keypad 110, the display 112, and
the earpiece 102. Surrounding user interface of the unit 100
with a loop antenna beneficially minimizes the space consumed by the antenna for the unit 100.
Referring now to FIG. 2 there is shown an exploded view
of the radiotelephone/pager unit 100 of FIG. 1 showing a
first preferred location of a pager antenna. FIG. 2 generally
includes: the hand grip 122 having the volume control
