Dual band compact antenna design using DCSRR

Abstract

Wireless communication technology has revolutionised the way people interact all around the world. The rate of access and the accuracy of the information conveyed have increased as technology and gadgets have advanced. Multi-frequency systems and devices are the results of the requirement for mobility and the integration of several radio modules into this kind of device. Due to the limited area, integrating many antennas and a diplexer into a single device is very challenging. This means an advanced antenna design must be simple, small, and simple to incorporate in addition to being dual or multiband capable. Microstrip printed antennas are the most promising alternative for use in small systems due to its various features such as low profile, compact configuration, simplicity of integration, and low fabrication cost. There are many techniques to make an antenna operate in multiband such as by incorporating structures like complementary split ring resonator(CSRR), SRS (split ring slot), SRR (split ring resonator) etc., dual polarization method, loading of metamaterial. The DCSRR (D shape complementary split ring resonator) is inserted into the antenna patch to enable multiband operation. So, in this paper, to achieve dual band response using this method, which supports Wi-Fi and C band applications at frequencies of 5.8 GHz and 7.1 GHz, respectively. In the suggested work, a good gain of about 1.98 dB at 5.8 GHz and 2.27 dB at 7.1 GHz was obtained, as well as an efficiency of 80 percent and 81 percent at the relevant frequencies. This characteristic has been achieved without compromising on the compact miniaturized size of antenna, which is 12 x 12 x 1.6 mm3.
