Antenna Array and Housing for Notebook Computers

      Disclosed is a method for placing antennas and associated
cabling to optimize the performance of an 800MHz-band cellular radio
integrated within a notebook computer.  The antennas and associated
cabling are protected from physical damage and are concealed when not
in use.

      Fig. 1 is an isometric view of an arrangement of antennas and
associated cabling as mounted to extend along surfaces of a notebook
computer 4.

      Fig. 2 is an isometric view of a plastic shroud 6, which is
attached to the back of the display 8 of the notebook computer 4,
using VELCRO* fasteners, together with a plastic side enclosure 14,
in an exploded relationship with an outer housing 16.  The shroud 6
and side enclosure 14 hold the antennas and cabling in the
relationship shown in Fig. 1.

      In this arrangement, the primary antenna 18 is a pullup dipole
used for both the transmission and reception of radio signals.  When
this antenna 18 is not in use, it may be pushed downward, to be
housed within left edge portion 20 of the shroud 6.  Additionally, a
diversity antenna 22 is a patch antenna used for reception only,
being mounted within central edge portion 24 of the shroud 6.  The
diversity antenna patches 25 are separated by approximately one wave
length to achieve good diversity performance in Rayleigh fading
environments.  The selection between antennas 18 and 22 is made under
control of a microprocessor withi...
