Frequency Switching of PIFA Using Split Ring Resonator
نویسندگان
چکیده
In this paper, a PIFA loaded with split ring resonator (SRR) is presented, in which frequency switching is performed by varying the radius of split rings. The proposed Planar invertedF antenna (PIFA) without metamaterial resonates at 7.46 GHz with return loss of -23.71 dB, gain value 5.41 dBi and bandwidth 361.8 MHz. Proposed PIFA structures with metamaterial loading resonates at multiple frequencies with gain and bandwidth enhancement in comparison to reference antenna. Size reduction is also accomplished after loading with metamaterial. Nicolson-Ross-Weir (NRW) method is employed to verify the single negative (SNG) metamaterial characteristics of split ring resonator. Design is simulated using HFSS Software.

Complementary Split Ring Resonator Effects on Radiation Pattern Reconfigurable Circular Microstrip Antennas
In this study, a radiation pattern reconfigurable microstrip antenna is designed and fabricated. The antenna’s radiation pattern is directed in 9 different angles by employing a radiating patch and embedding complementary split ring resonators (CSRR) on the ground plane. The radiating patch is of circular shape, while for CSRR elements both circular and rectangular shapes are investigated. The ...

In this paper, for the first time to our knowledge, we investigate the optical bi-stability in a compact parallel array of micro- ring resonators with 5μm radius, induced by optical nonlinearity. Due to the nature of perfect light confinement, resonance and accumulation process in a ring resonator, optical nonlinear effects, even at small optical power of a few milliwatts in this structure are ...

In this paper we proposed anovel multiband delay line which consists of two types of split-ring resonators: the broadiside coupled and the single split-ring resonator. Proposeddelay line exhibits two left-handed bands that can be shifted by twisting the split rings for certain angle or by changing their lengths. This delay line is suitable for design of multiband frequency scanning antennas sin...
متن کاملEnhanced Gain Planar Inverted-F Antenna with Metamaterial Superstrate for UMTS Applications
Planar inverted-F antennas (PIFA) are widely used in wireless hand-held devices due to their small-size, moderate bandwidth and radiation patterns. However, the radiation patterns of such antennas degrade when placed very close to a conductive finite ground plane. In this paper, an engineered magnetic superstrate is introduced to enhance the gain of PIFA antennas. The engineered magnetic supers...
