Abstract
This paper present the design of a circular patch microstrip antenna with enhancement in terms of bandwidth and gain using a dielectric double negative (DNG) split ring metamaterial radome. This radome is positioned on top of the CP antenna operating from 5.2 GHz to 6.4 GHz. The metamaterial radome comprises of two alternate split rings of negative permittivity, permeability and refractive index. The circular microstrip antenna bandwidth of 430 MHz has been realized by the presence of DNG metamaterial radome compared to 220 MHz without the radome. The gain has been increased as well from 1.84 dBi to 3.87 dBi.
Highlights
The enhancement of microstrip antennas using radomes enhances their practical application, besides protecting them from different environmental effects such as wind, rain, ice, ultraviolet radiation etc
The resonant frequency, input impedance and radiation characteristics of the zeroth-order resonant (ZOR) circular antenna are analyzed in terms of the physical parameters of the unit cells [13], a compact triple-band microstrip antenna based on MTM complementary split ring resonator (CSRR) with two different geometries loaded on the ground plane of the antenna
Results can be presented in graphs, Double Negative (DNG)-Split Ring Resonator (SRR) radome structure with the circular patch antenna is simulated using CST Microwave Studio electromagnetic simulator
Summary
The enhancement of microstrip antennas using radomes enhances their practical application, besides protecting them from different environmental effects such as wind, rain, ice, ultraviolet radiation etc. The resonant frequency, input impedance and radiation characteristics of the ZOR circular antenna are analyzed in terms of the physical parameters of the unit cells [13], a compact triple-band microstrip antenna based on MTM complementary split ring resonator (CSRR) with two different geometries loaded on the ground plane of the antenna. This work explores the design of such metamaterial split, ring radome for a circular patch antenna operating at 5.8 GHz. A method is used to extract the effective permeability, refractive index, and impedance from S-parameter to analyze whether the metamaterial structure is DNG at the same frequency. A method is used to extract the effective permeability, refractive index, and impedance from S-parameter to analyze whether the metamaterial structure is DNG at the same frequency Another advantages of using Double Negative (DNG) Split Ring Resonator (SRR) radome. This new approach come up with a new solution called metamaterial radome, which play an important role in the antenna design due to its interesting and unusual properties
