Constantly, antenna plays an important role in expanding the wireless communication systems in different technology applications for example, but not limited to, IoT communications and automotive radar systems. On the other hand, the Bluetooth-Low-Energy (BLE) benefits different sorts of applications, as it offers (i) a very low power consumption, (ii) a very fast data transfer, (iii) and an inexpensive/efficient solution as well. This research is a part of AES-Nordic AB projects, which intends to improve the connection between remote vibration sensors and the measurement device. The vibration sensor sends the captured data to the receiver via a wired connection which, in turn, creates a lot of complications, in terms of access limitation and a connection loss vulnerability. The aim of this thesis is to remove these limitations and improve the overall performance using a wireless connection over BLE. This thesis project presents a novel and an efficient system that eliminates the wired-connections shortcomings by involving a new inverted F-antenna design which transfers data from remote sensors to the measurement device. The produced antenna needs to satisfy the following conditions: (i) resonant frequency of 2.44GHz, (ii) isotropic directivity, (iii) minimum coverage of 20-meters. The other goal of this thesis is to compare the presented antenna with commercially available solutions, such as helical and monopole antennas for the purpose of showing the efficiency of the presented solution. The produced antennas were tested in the anechoic chamber and the measurement results show that the designed inverted F-antenna has a comparatively better performance than its peers.
