Abstract
A slot fed microstrip antenna (100) provides improved efficiency through enhanced coupling of electromagnetic energy between the feed line (117) and the slot (106). The dielectric layer (105) between the feed line (117) and the slot (106) includes magnetic particles (114), the magnetic particles (114) preferably included in the dielectric junction region (113) between the microstrip feed line (117) and the slot (106). A high dielectric region is preferably also provided in the junction constant to further enhance the field concentration effect. The slot antenna (100) can be embodied as a microstrip patch antenna (200).
Claims16
A slot fed microstrip antenna, comprising:
- an electrically conducting ground plane, said ground plane having at least one slot;
- a feed line for transferring signal energy to or from said slot, and
- a first dielectric substrate material disposed between said feed line and said ground plane, wherein at least a portion of said first dielectric substrate includes magnetic particles.
