Abstract

The development of a horizontal version of the tuned, wide-strip low-impedance loop antenna (LILA) for use as a short-wave broadcast receiving antenna is recounted. The horizontal loop antenna (HLA) received the horizontal electric field component of the down-coming sky wave (actually, the projection of the vertical magnetic field component) relatively unattenuated, for elevation angles of arrival up to about 45 degrees , while rejecting the predominantly vertically-polarized ground-wave electric field by 20 to 30 dB.<>
