A Wide Band Microstrip Antenna Integrated with Complementary Split Ring Resonator (CSRR) for WLAN and C Band Applications

This paper presents a Complementary Split Ring Resonator (CSRR) integrated microstrip antenna with wide bandwidth for wireless LAN (5.15 to 5.25 GHz and 5.72 to 5.85 GHz) and C-band (downlink from 3.7 to 4.2 GHz and uplink from 5.925 to 6.425 GHz) communication. It covers the frequencies from 3.97 to 6.6 GHz. The proposed antenna has a maximum gain of 4.2 dB at 4.15 GHz and the bandwidth is about 49.8% wide. Simulated gain, impedance bandwidth and radiation pattern of the proposed antenna is presented in this paper.
