Abstract
An antenna for use in a conveyor system in which items on which radio frequency identification tags are disposed are moved on a conveyor along a path of travel, includes a ground plane, a substrate having a bottom surface received adjacent the ground plane, at least one patch element disposed on a top surface of the substrate, a cover received adjacent the top surface of the substrate, and a front static conductive strip disposed along a front edge of the cover. The antenna is disposed beneath the conveyor and a front edge of the antenna is transverse to the path of travel. The front static conductive strip is electrically connected to the ground plane such that an electrostatic discharge event adjacent the front static conductive strip is discharged to the ground plane.
