Abstract :
In this contribution we investigate two variations of H-shaped planar antennas by using an ATLM field solver. The antennas are coupled in a different way to a microstrip feedline. The coupling is done alternatively by an aperture slot and a viahole. Using the ATLM method for antenna design, structures with finite metalization thickness and viaholes are modeled as easily as strictly planar structures. The calculated S-parameters of the antenna structures are compared to measured results.
