Abstract
:Antennas play a key role in communication systems,but single-band antennas no longer meet today's -
fore,the study of mult-i band antennas is necessary. In this paper, a mult-i band microstrip antenna based on coplanar
waveguide feeding is microstrip antenna consists of an annular slit etched on the conductive surface of the sub-
strate as the initial ,electric dipole,metamaterial Complementary Split Ring Resonator (CSRR)with Inter-
Digital Capacitance Loaded Loop Resonator (IDCLLR),and a U-shaped slot are loaded at different positions of the substrate to
achieve mult-i frequency resonance of microstrip results show that the antenna is capable of operating simultane-
ously in the Wireless Local Area Network (WLAN)band ( ~ 1 GHz),World Interoperability for Microwave Access
(WIMAX)band (3 .6 3 ~ 3 .74,5 .45 ~ 5 .6 6 GHz),the uplink frequency for satellite communication services (3 .94 ~
GHz),International Mobile Telecom System(IMT-2020 (5G))band (~ GHz),satellite communication service
