HIGH EFFICIENCY SLOT FED MICROSTRIP ANTENNA HAVING AN IMPROVED STUB |
摘要 |
A slot fed microstrip antenna (100) having an improved stub (118) provides enhanced efficiency through more efficient coupling of electromagnetic energy between the feed line (117) and the slot (106). A dielectric layer (105) disposed between the feed line (117) and the ground plane (108) provides a first region (112) having a first relative permittivity and at least a second region (113) having a second relative permittivity. The second relative permittivity is higher as compared to the first relative permittivity. The stub (118) is disposed on the high permittivity region (113). The dielectric layer can include magnetic particles, which are preferably disposed underlying the stub. |
