چکیده
A novel method of enhancing radiation performance is demonstrated by applying a hybrid reflector composed inhomogeneous metamaterial elements to four-arm log-periodic toothed antenna. The operation the antennas various cells observed, and causes deterioration narrow bandwidth are investigated through field distribution analysis. arranged in suitable positions under antenna for good wide according AMC EBG characteristics. In proposed reflector, surface wave suppression characteristics used impedance stabilization placing I-shaped cell inactive region fabricated with dual linear polarization capability verified measuring co- cross-polarization patterns. newly represents an over 4 dBi realized gain within ratio 11.6:1.

متن کاملA Novel Circularly polarized dielectric resonator antenna with Branch-Line Coupler and Log-Periodic Balun
A new shaped circularly polarized dielectric resonator antenna (CP DRA) is studied with branch-line coupler and log-periodic balun for the GPS application. Since the coupler and balun are located under the DRA, it does not increase the footprint of the antenna, as a result the system is very compact. Two configurations are considered in this paper. In the first configuration, an external 50Ω lo...
متن کاملA Novel Miniaturized Log Periodic Antenna
Log-Periodic Dipole Antenna (LPDA) is a common and important broadband antenna, due to its non-frequency dependent characteristic. However, in the conventional design, the physical size is restricted to the longest oscillator dipole w ith the low est resonant frequency, which is quite large and constrains its application. To realize the antenna miniaturization, many methods, including loading t...
