Dual band IFA with overlapping elements

Abstract

An antenna for wireless devices is disclosed, featuring a dual band inverted F antenna (IFA). The dual band IFA antenna includes a low band arm as well as a high band arm projecting from the low band arm, both utilizing a shared feed to facilitate dual-band operation. The high band arm, meandered across one or more planes, overlaps the low band arm to induce capacitive coupling, tuning the antenna for specific frequency bandwidths. The meandered low band arm generates regions of strong and weak electric fields, with a vertical portion of the high band arm aligned with one of these regions for optimal tuning. This configuration allows the antenna to maintain a compact form factor while resonating at both the low and high band frequencies. In some embodiments, the antenna is constructed by cutting and/or bending a continuous electrically conductive material.
