Effect of Finite Ground Plane on Performance of Compact Air-Suspended Rectangular Microstrip Antenna for 5G Applications

摘要

This paper presents details of the effects of shorting along the width of the air-suspended rectangular microstrip antenna (RMSA). The entire width of the patch is shorted using a number of shorting pins and as the number of shorting pins increases, the gain, bandwidth, and resonance frequency of the antenna increase. By decreasing the shorting width, the antenna can be made more compact. For the shorted compact air-suspended RMSA the effects of the finite ground plane on its performance have been analyzed. When the geometric parameters of the ground plane are changed, it affects the gain, bandwidth, resonance frequency, and back lobe radiation. Various graphs have been presented to choose the optimum performance depending on the size constraints.
