Abstract
There is disclosed a dual band antenna device including a dielectric substrate () having opposed first and second surfaces and a groundplane () on the second surface. A microstrip transmission line () is provided on the first surface, and a dielectric pellet () is mounted on the first surface on the microstrip transmission line (). A bifurcated planar inverted-L antenna (PILA) component () is also mounted on the first surface, the PILA component () having first () and second () arms which extend over and contact a surface of the dielectric pellet (). The first arm () contacts a different area of the surface of the dielectric pellet () than the second arm (). The antenna device provides good operation at both 2.4 GHz and 5.5 GHz frequency bands.
