Dual Band Modified Split-Ring Resonator Microstrip Antenna for Wireless Applications

In this work, a design is proposed to improve the performance of the conventional series-fed dipole pair (SDP) antenna by adding split-ring resonator (SRR). Firstly, a conventional SDP antenna that functions in the frequency range of 1.7–2.7 GHz is designed by adjusting the distances of the dipoles and the space between the two presentations. Later, a couple of SRR is mounted above the top dipole to improve the antenna performance. Then, the effects of SRR on the impedance, bandwidth and gain are examined. The experimental results show that the proposed antenna has an increased gain. The antenna is simulated, and parameter measurement is done using a CST microwave studio. The proposed antenna can be used for GPS, WIFI and Wi-MAX.
