Slot fed microstrip antenna having enhanced slot electromagnetic coupling

摘要

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).
