2x1 slotted MIMO antenna with slotted ground for high frequency wireless application

Abstract

The antenna is the radiating device for transmission and reception of signals. Multi transmitting and receiving antennas are superior to single antenna. The MIMO system fulfils the higher capacity requirements as well as it gives high reliability. In this research work antenna is designed using MIMO techniques. The strip patch type is elementary MIMO antenna that can be used for small devices and other low-profile wireless applications operating at 11.6 GHz. The two-element slot antenna utilising silted/slotted ground was the design's main focus. The developed 2x1 MIMO antenna with slotted ground produces −43 dB return loss and the frequency region 11.1 to 12 GHz for strong isolation at 11.6 GHz frequency. It is shown how to use various antenna parameters including gain, ECC, and radiation pattern. The antenna's geometry is based on a rectangular MPA and a silty or slotted ground combination. While the shape of the intended MIMO antenna gives sufficient isolation that is more than 13.5 dB in the requested band, no isolation strategy was used in the design. The selection of material while designing of patch antenna is also very important. The results of various antenna parameters may vary accordingly material chosen. In this paper designed antenna considered FR4 material while optimizing the design. For the design of antennas, various types of dielectric materials are utilised. High dielectric material FR-4 is suitable in low profile antenna design for frequency less than 10 GHz. The various MIMO antenna design parameters are discussed in the research shows the good value for wireless application.
