Tolpa for mm-wave: A wideband low profile, omnidirectional vertically polarized antenna

In an article (Zürcher, Microwave Opt Technol Lett 55 (2013), 516–521) published in 2013, a new antenna called tripod omnidirectional low profile Antenna has been presented. It is vertically polarized and has a radiation pattern similar to the classical monopole on a ground plane, with numerous potential applications for mobile communications, UWB, and others. The present article describes a scaled version of this antenna designed to work at mm-wave frequencies.
