Restricted access - publisher's policyMiniature behaviour of microstrip antennas with Sierpinski bowtie geometry is investigated and the existence of fracton modes is studied. A fracton mode is a mode found at a higher frequency than the one obtained for the ...
Theoretical and practical experiments for a single antenna gain testing method. Application to wireless devices Anguera, Jaume; Sanz, Alfonso; Ko, Young Ji; Borja, C.; Puente Baliarda, Carles; Soler, Jordi (2007-08)
Restricted access - publisher's policyA compact antenna gain measurement system suitable for wireless devices is presented. The method needs the antenna under test, a planar electric conductor, and a vector analyzer. It is possible to obtain the total gain ...
