Appeal No. 96-1637
Application 08/130,940
reasoning that “the waves radiated by the system of Rogers et al
are vertically polarized since long 'waves' (commonly used in
Naval communications to communicate around the world, particularly
with submarines) are propagated between the antenna element and
the ionosphere”. The position that Rogers’ antenna is for
transmitting and receiving substantially vertically polarized
radio waves is reasonable in view of the close similarity of the
structure of Rogers’ and appellants’ wire antennas. Furthermore,
the examiner’s position is supported by the text McGraw-Hill
Encyclopedia of Science and Technology, vol. 1, ANTENNA
(ELECTROMAGNETISM) Polarization, New York, 1971, at pages 483 and
484. In Figures 3 and 4, it is disclosed that the radiation field
is in a plane orthogonal to an oscillating electron and an
oscillating doublet in an antenna wire.
Such being the case, the horizontal antenna of Figure 8 of Rogers
would produce substantially vertically polarized radio waves.
We are not persuaded by the other argument made by
appellants that there is nothing in Rogers to suggest deploying an
antenna wire on and along an upper surface of a sea ice
