Abstract (en)
A feeding method for an IC compatible multi-layer planar antenna (10), said antenna comprising a ground plane (11) and Li substantially parallel plates (12), i=1, 2, ... N with N‰¥2, the method comprising: - at least providing first current injection means (20, 21) in a first plate L 1 , for injecting current to a first layer and providing second current injection means (20', 21') in a second plate L 2 , for injecting a current to a second layer, the method further comprising - injecting a current to said first current injection means and simultaneously or sequentially injecting current to said second current injection means, whereby the antenna operates at a first operating frequency-band f 1 and/or at a second operating frequency-band f 2 . The invention also relates to an IC compatible multi-layer planar antenna with multiple feeding points.
