Design of 7 GHz Microstrip Patch Antenna for Satellite IoT- and IoE-Based Devices

摘要

The next industrial revolution brings machine to machine (M2M) connectivity, Internet of Things (IoT), and Internet of Everything (IoE), and this will take governments, businesses, and people interaction with each other to new level. The global satellite IoT and M2M device market will reach 5.96 million by 2020. Both machine and human can communicate sense and trigger via IoT-based frameworks over a large or remote geographical area using satellite communication. The signal can be sensed at remote location (sea, air, or other unconnected location) and can be uplinked to satellite and can be provided to a central control station. IoT devices should be compact in size so that they can be mounted easily. Microstrip Patch Antenna (MPA) is having advantage of compact design, light weight, easy fabrication method, and low profile over the conventional antennas. Due to their planar structure, microstrip patch antenna is widely used in wireless communication, satellite communication, and in many areas where electromagnetic waves are used. In this paper, inset-fed Microstrip Patch Antenna (MPA) is designed and analyzed for 7 GHz frequency band for satellite communication. The electric field norm plot, radiation pattern are analyzed. Directivity is approximately 12.016 dB, and return loss (S11) calculated is -20.5 dB, and front to back ratio is calculated as 19 dB.
