Dualband Bent Slot Loaded Patch Antenna | Antenna Magus

Image of the Dualband bent slot loaded patch antenna.

This compact planar antenna supports TM01 and TM10 modes on the patch structure due to the introduction of slots, resulting in dual-band operation. The ratio between the upper and lower frequencies is mainly controlled by the length to width (aspect) ratio of the patch.

The radiation patterns at the two operating frequencies are similar in shape but are orthogonal with respect to one another.

Typical total gain pattern at the lower (f1) and upper (f2) operating frequency.
