Modified series-fed dipole pair antenna using split-ring resonator directors for dual-band operation

Abstract

The performance of the conventional Series Fed Dipole Pair Antenna (SDP) antenna is raised by adding Split Ring Resonator (SRR). Firstly, a conventional SDP antenna that operates in the frequency range of 1.8-2.62 GHz is designed by adjusting the lengths of the dipoles and the distance between the two displays. Afterwards, a couple of SRR is mounted above the top dipole to improve the antenna performance. Compact size and increase in bandwidth and gain are attained.
