A miniaturized dual-band differential-mode antenna with a broadband 1∶1 balun is integrated in a 1-mm thick multi-layer PCB substrate. A broadband balun for the 2.5 GHz and 5.2 GHz dual-band, was designed and fabricated with a broadside-coupled line structure. With a proposed deembedding method, mixed-mode S-parameters of the unit balun were extracted with… CONTINUE READING
