Metamaterial Structure Based Dual-Band Antenna for WLAN

With the development of communication technology and wide application 5G information technology, various mobile equipment manufacturers have higher demands for compact, small, light, low-cost, dual-band antennas. Therefore, this paper designs a metamaterial structure-based antenna with operating frequencies covering wireless local area network (WLAN) bands. According to simulated measured results, bandwidths below −10 dB include 2.326 − 2.859 GHz 4.995 5.854 GHz. The results are in good agreement ones. Moreover, radiation energy proposed is relatively concentrated, gain can reach 3.5 dBi 3.53 at center two All show that novel CPW-fed compact structure, low cost, successfully implemented.
