摘要：

A novel miniaturized D shape split ring resonator (SRR) antenna is proposed for dual band (3.6 GHz and 4.7 GHz) applications. This proposed antenna structure has dimensions of 18 x 20 x 0.8 mm(3) which is built on FR4 dielectric constant (epsilon(r)=4.4). This antenna consists of top and bottom side dual SRR creating dual band resonant frequency which is excited from microstrip line as monopole and slotted partial ground plane for better impedance matching. The microstrip line (monopole) is creating a resonance frequency at 4.7 GHz and the SRR is responsible for creating resonance frequency at the frequency of 3.6 GHz. The parametric study of microstrip line and the position of SRR has been analyzed. The D shape SRR in the monopole is generating another resonating frequency at 3.6 GHz. The metamaterial property of proposed D shape SRR is also verified to validate the resonance frequency. The antenna radiation measurement is carried out in Antenna Research Centre (ARC) FKE, Universiti Teknologi MARA, Malaysia. Both simulated and measured results agreed well. Measured gain achieved with this dual band antenna is around 2-3 dB.
