Design and Fabrication of a Low-Cost, Multiband and High Gain Square Tooth-Enabled Metamaterial Superstrate Microstrip Patch Antenna

Abstract

The manuscript represents a novel square tooth-enabled superstrate metamaterial loaded microstrip patch antenna for the multiple frequency band operation. The proposed tooth-based metamaterial antenna provides better gain and directivity. Four antenna structures are numerically investigated for the different geometry of the patch and tooth. These proposed structures are simulated, fabricated, measured, and compared for the frequency range of 3 GHz to 9 GHz. The electrical equivalent model of the split-ring resonator is also analyzed in the manuscript. The comparative analysis of all of the proposed structures has been carried out, in terms of several bands, reflectance response, VSWR, gain and bandwidth. The results are compared with previously published works. The effects are simulated using a high-frequency structure simulator tool with the finite element method. The measured and fabricated results are compared for verification purposes. The proposed structure provides seven bands of operation and 8.57 dB of gain. It is observed that the proposed design offers the multiple frequency band operation with a good gain. The proposed tooth-based metamaterial antenna suits applications, such as the surveillance radar, satellite communication, weather monitoring and many other wireless devices.

Highly Efficient and Multiband Metamaterial Microstrip-Based Radiating Structure Design Showing High Gain Performance for Wireless Communication Devices

“…Their response is analyzed regarding dire ity, gain response, electric field, and radiation pattern. Antenna directivity represents the intended intensity concerning the average p in all directions [36]. The higher directivity value also represents the higher gain v The proposed design provides a narrow-band response for the different resonating frequencies.…”

A Small Size Wideband M-shaped Polygonal Slot Antenna for X-band Satellite Applications

“…They have been widely used in high-performance satellites, CubeSats, and wireless communication devices [8][9][10]. However, these antennas suffer from major drawbacks such as low bandwidth, low power handling capacity, and low gain, which significantly limit their performance [11]. To overcome these limitations and achieve wide bandwidth and acceptable gain with very small antenna sizes, researchers have focused on developing new antenna designs.…”
