A new approach is investigated to enhance the gain of Microstrip Antenna Array using the substrate integrated waveguide (SIW). Integration of SIW is implemented firstly in single microstrip antenna and then in 4×1 array. Rectangular microstrip antenna array is backed with SIW cavity is designed to improve gain as well as bandwidth for wireless communication applications. Proposed antenna array acquires advantage of easy integration. Improvement in results is presented using simulation output of reflection coefficient, VSWR, and gain. Bandwidth is improved up to 10.98 % at frequency 2.3 – 2.5 GHz. The new approach gives an improvement in gain by 9.434 dB.

Abstract— This paper describes 2 x 2 triangular microstrip patch antenna using T-junction with quarter wave transformer. By regulating the distance in patch antenna and adjusting feed position, bandwidth can be obtained and by using an array, directivity is enhanced. The requirement of large bandwidth, high directivity, and minimum size leads to the design of 2 x 2 triangular microstrip patch antenna array feeding with T-junction network operate at 5.5 GHz. An antenna designed on an FR4 substrate that had a dielectric constant (r) 4.4, a loss tangent 0.02 and thickness of 1.6 mm. Simulated results showed that designed antenna has directivity 12.91 dB and bandwidth 173 MHz with VSWR 1.07 using T-junction feeding network. The proposed 2 x 2 triangular array has the benefit of light weight, simplicity of fabrication, single layer structure, and high directivity.

This paper presents new design of artificial magnetic conductor structure along with feed line. 4 × 1 microstrip patch antenna array using AMC improves performance of antenna. AMC structures are used in design low profile antennas. High gain, minimum size and larger band width required for communication system. This leads to design patch antenna array. So this paper presents four element microstrip patch antenna array with artificial magnetic conductor structure. It uses FR4_epoxy as dielectric substrate. 4 × 1 microstrip patch antenna array is designed using HFSS simulation software. Simulation and measured results are compared.
