AbstractIn this article, a new structure comprising of a novel compact slot loaded polarization dependent Electromagnetic Band Gap structure (SLPDEBG), which enhances the performance of circularly polarized rotated square patch antenna by placing SLPDEBG unit cells around it, has been designed. The proposed antenna, having dimensions 0.640 λo x 0.640 λ x 0.0128 λo (λo stands for the free space wavelength at 2.39 GHz), shows that the measured impedance bandwidth and AR bandwidth is 120 MHz and 50 MHz, respectively, with a peak gain of 3.52 dB. Some prominent features of the proposed structure are: front to back ratio of 64, 3 db, beamwidth of 92° at xz-plane and 74° at yz-plane. This prototype antenna finds its application in wireless communication of ISM band. Good performance of the proposed antenna is verified by the close agreement between the simulated and measured results.

This paper describes enhancements in the performance of four element microstrip antenna array. The conventional microstrip antenna array is producing gain equal to 6.81dB. With the introduction of U shape patch type electromagnetic band gap structure, the proposed microstrip antenna array is producing an improved gain of 20.33dB. It is producing reduced mutual coupling of -31.44, -36.41 and -31.62dB respectively. The radiation characteristics of the proposed microstrip antenna array are improved with appreciable decrease in back lobe radiation and increase in forward power. It is resonating at single band at 5.53GHz, producing an overall bandwidth of 109.45%, against 4.89% of conventional microstrip antenna array. Microstrip antenna arrays are designed using Mentor Graphics IE3D software and measured results are obtained using vector network analyzer.

Gap Structure

Application of electromagnetic band-gap (EBG) structure and its use in the design of antenna and microwave integrated circuits is becoming more attractive. The recent electromagnetic band-gap structure method is capturing more importance in antenna design due to its uniqueness properties to suppress the propagation of surface waves in microstrip patch antenna. In this paper a square microstrip antenna is designed and its performance parameters are compared with geometry designed on EBG structure.  The square antenna of 29 mm x29 mm  size is designed at 2.455 GHz and analysis is done using IE3D  simulation software. The proposed work mainly focuses on modification of antenna using electronic band gap structure (EBG). The antenna parameters such as Return loss, VSWR, Gain and Bandwidth, with and without EBG are obtained using IE3D simulation tool. The Electromagnetic band-gap structures have been used to improve the performance of the gain of the antennas and radiation patterns. One of the main advantages of electromagnetic band-gap structure is its ability to suppress the surface wave current present on the microstrip antenna. Combining the square patch with EBG structure, the bandwidth of the antenna has been increased by 34.66%, and attained  gain of 44.44%  at resonant frequency around 2.4 GHz as compared to the antenna without EBG..
