Microstrip log-periodic antenna array having grounded semi-coplanar waveguide-to-microstrip line transition

摘要

A log-periodic antenna having a layer of dielectric media interposed between a microstrip log-periodic portion and a slot log-periodic portion is described. Also described are antenna embodiments having a curvilinear, electrically conductive feed line and a substantially co-extensive curvilinear slot transmission line and additional embodiments including an array of two or more log-periodic antennas.
