Abstract: An electrically small (ES) dual-band, dual-polarized omnidirectional dipole antenna is presented. This design combines two dual-band ES antenna (ESA) cells arranged in a cross-perpendicular ...

We take a closer look at how two of the best GPS dog collars fare against each other in this SATELLAI Collar vs Halo Collar 5 comparison.

Abstract: A new class of via-less dual-band wide-stopband filtering antenna is proposed. The proposed topology is based on a stacked patch antenna structure, which is excited using a proximity-coupled ...
