Abstract
In one embodiment, a meander slot antenna includes a conducting sheet having a meander slot defined therein. The meander slot has a closed area defined by the conducting sheet. An electrical microstrip feed line crosses the meander slot. The electrical microstrip feed line and meander slot provide a magnetically coupled LC resonance element. A dielectric material has at least one conductive via therein. The at least one conductive via electrically connects the electrical microstrip feed line and the conducting sheet at a side of the meander slot. The dielectric material otherwise separates the conducting sheet from the electrical microstrip feed line. Other embodiments are also disclosed.
