Design and simulation of a metamaterial based dual band antenna using Rectangular Complementary Split Ring Resonator in the ground plane for mobile and wireless applications

This literature demonstrates the study of design and parametric characterization of a tree shaped microstrip patch antenna with dual band notch characteristic for Ultra wideband (UWB) applications. This proposed design is characterized by an enhanced impedance bandwidth of 2.2–19.5 GHz (159% Percentage bandwidth) with dual band notch characteristic at Wi-MAX band (3.3–3.7 GHz) and upper WLAN band (5.15–5.85 GHZ). The wide impedance bandwidth is achieved by using a special tree shaped radiator with modified front and back ground plane. The band rejection in wireless local area network (WLAN) band is achieved by etching a Rectangular Split Ring Resonator (RSRR) structure in the radiator part and for Wi-MAX, a Spiral shaped Defected Microstrip Structure (SDMS) in the feed mechanism. The overall dimensions of the proposed antenna are 28 × 35 × 1.6 mm3. The antenna is characterized by high gain (about 7.5 dB max) in the entire operating frequency band except the notched frequency bands. The simulated and the experimental results are in good agreement. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:1658–1661, 2016

The antenna's design and frequency reconfiguration have a significant impact on its performance, which makes it perfect for a particular use case such as the Internet of Things. In this, study developed a unique metamaterial patch antenna design using a frequency reconfiguration technique. In the study, the metamaterial microstrip patch antenna (MMPA) was deployed in an Internet of Things application utilizing a frequency reconfiguration approach, achieved with the help of a PIN Diode. Changing the bias of two PIN diode switches altered the resonating frequency. An FR-4 substrate with a copper patch forms the proposed antenna. The suggested antenna construction has dimensions of 23 x 19 〖mm〗^2. Two steps are involved in the design of a reconfigurable multiband antenna. The first designed Monopole for a Single Band with a centre frequency of 4.0GHz and the Second designed Multiband using a Rectangular Split Ring Resonator (RSRR) on the Ground Plane which includes two PIN diodes as switches, is evaluated in the ON-ON, OFF-ON, ON-OFF, and OFF-OFF switching scenarios. Antenna performance parameters like Gain, reflection coefficient, radiation efficiency, and standing wave ratio of voltage are used to estimate the presentation of the suggested antenna. At the Operating frequency of 3.6 GHz, the suggested antenna's efficiency and gain are 1.68 dB and 81%, respectively.

This paper presents a design of highly effective triple band microstrip antenna for wireless communication applications. The triple band design is a metamaterial-based design for WLAN and WiMAX (2.4/3.5/5.6 GHz) applications. The triple band response is obtained by etching two circular and one rectangular split ring resonator (SRR) unit cells on the ground plane of a conventional patch operating at 3.56 GHz. The circular cells are introduced to resonate at 5.3 GHz for the upper WiMAX band, while the rectangular cell is designed to resonate at 2.45 GHz for the lower WLAN band. Furthermore, a novel complementary H-shaped unit cell oriented above the triple band antenna is proposed. The proposed H-shaped is being used as a lens to significantly increase the antenna gain. To investigate the left-handed behavior of the proposed H-shaped, extensive parametric study for the placement of each unit cell including the metamaterial lens, which is the main parameter affecting the antenna performance, is presented and discussed comprehensively. Good consistency between the measured and simulated results is achieved. The proposed antenna meets the requirements of WiMAX and WLAN standards with high peak realized gain.
