With the rapid progress of the use of miniature sized antennas, wireless communication technology has quickly risen. Not only have the size of the antenna but also its cost, efficiency and ease of assembly all been taken into account during the antenna design. Conformal antennas are suggested to satisfy all these requirements. Conformal antennas have broad commercial, defense and several civil services applications. In aircraft and boats it is the most important and necessary time. Patch antennas are often regarded the best choice for such conformal antennas. In this paper, we address the conformal transmitters with different substrates used for antenna design. With this article, we create a modeling of conformal antennas with latest developments by examining early events

Recent Advances

In wireless communication technology, due to fast advancement use of small size antenna has rapidly increased. Not only the antenna size, but also its cost, performance, eases of installation everything have been taken care while designing the antenna. To meet these entire requirement conformal antennas is proposed. Conformal antennas have wide applications in commercial, defense and several civil, systems. In aircrafts and ships they are the need hour and most essential. For such conformal antennas the Patch antennas are often considered as the better candidate. In this paper, we discuss the conformal antennas with various substrates used for designing the antenna. Through this paper, we develop a modeling of conformal antennas with recent advances through surveying of early manifestations

A smart helmet is a wearable device that has attracted attention in various fields, especially in applied sciences, where extensive studies have been conducted in the past decade. In this study, the current status and trends of smart helmet research were systematically reviewed. Five research questions were set to investigate the research status of smart helmets according to the year and application field, as well as the trend of smart helmet development in terms of types of sensors, microcontrollers, and wireless communication technology. A total of 103 academic research articles published in the past 11 years (2009–2020) were analyzed to address the research questions. The results showed that the number of smart helmet applications reported in literature has been increasing rapidly since 2018. The applications have focused mostly on ensuring the safety of motorcyclists. A single-board-based modular concept unit, such as the Arduino board, and sensor for monitoring human health have been used the most for developing smart helmets. Approximately 85% of smart helmets have been developed to date using wireless communication technology to transmit data obtained from smart helmets to other smart devices or cloud servers.

Because of rapid development of wireless communication technology, there is an increasing adoption of mobile advertising, such as location based advertising (LBA). To what extent can LBA improve advertising effectiveness is an important topic in the field of wireless communication technology research. Most researches quantify long term impacts of advertisings by VAR (Vector Autoregressive) model. However, compared to VAR model, VECM (Vector Error Correction Model) is a better method in that it allows one to estimate both a long-term equilibrium relationship and a short-term dynamic error correction process. In this study, we employ VECM to explore LBA’s (Location Based Advertising) and PUA’s (Pop-up Advertising) sales impact in both short and long terms. The developed VECM reveals that LBA’s sales impact is about more than2 times as big as PUA’s in short dynamic term and nearly 6 times bigger than PUA’s in long equilibrium term. These findings add to advertising and VECM literatures. These results can give managers more confident to apply wireless communication technology to advertising.
