Abstract:
An electromagnetic compatibility test antenna array comprising a shaped element antenna including a first set of opposed triangular shaped and substantially planar antenna elements projecting in substantially opposite directions and having respective apexes connected to respective ones of elongated conductor means, a second set of opposed rectangular shaped antenna elements connected only to respective ones of said opposed shaped antenna elements of said first set at distal end base members thereof, respectively, and extending in planes substantially normal to a substantially common plane of said antenna elements of said first set;a log periodic dipole antenna array connected to said first set of antenna elements, respectively, via said respective conductor means; andsaid rectangular shaped elements and said triangular shaped elements are each characterized by wire or tube struts defining an outline of said rectangular shaped elements and said triangular shaped elements, respectively, at least one of said triangular shaped elements and said rectangular shaped elements include intermediate strut members extending between the strut members which define said outline, and said antenna array exhibits an antenna factor of less than 10 decibels in a signal receive or transmit operating mode for electromagnetic radiation signals having a frequency of between about 25 megahertz and 160 megahertz.
