Stupendous progress in heterogeneous communication technologies has allowed smart city gadgets to communicate with one another. However, these communication technologies are not able to offer the connectivity that is needed in smart cities because of the coexistence of hundreds and thousands of devices, which leads to various problems like, high energy consumption, interoperability support among the heterogeneous wireless networks, interference management, scalable wireless solutions, and mobility management. Machine-to-Machine (M2M) communication is one of the key enablers for advanced applications and services. The aim of this bibliometric review is to understand the extent of the existing literature for the area of M2M communications in smart cities using Microstrip antennas. This bibliometric analysis is majorly based on the Scopus database and tools such as VOSviewer and ScienceScape. The research articles published between the years 2013 to 2021 were considered. We observed from this bibliometric analysis that the major publications found are from conference papers, articles and conference reviews by Indian publications followed by Irish, Japanese and Chinese publications. The majority of the contribution is by the subject areas of Engineering, Computer Science, Physics and Astronomy, Material Science and Mathematics.
