| Popis: |
A circular microstrip patch antenna partially loaded with homogeneous substrate and superstrate consisting of double-negative (DNG), epsilon negative (ENG), and mu negative (MNG) is investigated to observe the changes in resonance. It is observed that embedded double-negative substrate placed under the patch displays dual band resonance characteristics with moderate realized peak gain bandwidth and superstated disc increases the gain as high as 10 dBi. Embedded e-negative substrate provides moderate peak gain with bandwidth as high as 500 MHz and superstate metamaterial depicting dual resonance phenomena with similar gain in both bands. In either case of embedded substrate and superstate, µ- negative material exhibits dual band characteristic with poor impedance matching. The DNG or ENG metamaterial embedded substrate antenna exhibits broadside null in its elevation plane radiation pattern but that is not observed for the case of metamaterial superstate disc loading on patch. |
