摘要
There is disclosed a dual band antenna device including a dielectric substrate ( 6 ) having opposed first and second surfaces and a groundplane ( 7 ) on the second surface. A microstrip transmission line ( 4 ) is provided on the first surface, and a dielectric pellet ( 5 ) is mounted on the first surface on the microstrip transmission line ( 4 ). A bifurcated planar inverted-L antenna (PILA) component ( 1 ) is also mounted on the first surface, the PILA component ( 1 ) having first ( 2 ) and second ( 3 ) arms which extend over and contact a surface of the dielectric pellet ( 5 ). The first arm ( 3 ) contacts a different area of the surface of the dielectric pellet ( 5 ) than the second arm ( 2 ). The antenna device provides good operation at both 2.4 GHz and 5.5 GHz frequency bands.
