Abstract
In this paper, a quasi-Yagi antenna for an indoor location tracking system is proposed. The performance of the proposed antenna was verified by testing it using an indoor location tracking system. To improve the bandwidth and gain, two parasitic directors were added near the dipole. The performance verification of the proposed antenna is explained, along with a performance comparison of the VSWR (voltage standing wave ratio) radiation pattern and the realized gain. The proposed antenna was connected to an NVA-R661 module of Xethru Inc. for indoor location tracking. The proposed antenna exhibited a wide bandwidth of 4.36 GHz by satisfying a VSWR ≤ 2 from 5.03 to 9.39 GHz, the maximum gain was 6.46 dBi in the 8 GHz band. The radiation pattern exhibited a good directivity characteristic within the proposed band. The location tracking result of a moving target clearly describes the route of the target along a moving line.
Highlights
While GPS, the main outdoor location tracking system, has shown high performance and precision, various methods for an indoor location tracking system have been studied due to the absence of a clear solution [1,2].Conventional indoor location tracking solutions and security solutions have various problems.Good performance can be difficult to achieve in image-based systems if sight is covered by obstacles such as fog and smoke
The and, fabricated quasi-Yagi antenna was fabricated as a quasi-Yagi to improve the bandwidth and connected to an NVA-R661, verifying the validity of the indoor location tracking systems
The fabricated quasi-Yagi antenna was proposed for an indoor location tracking system
Summary
While GPS (global positioning system), the main outdoor location tracking system, has shown high performance and precision, various methods for an indoor location tracking system have been studied due to the absence of a clear solution [1,2]. An antenna for an indoor location tracking system is proposed The performance of this antenna was verified by connecting it to the impulse radar-based technology of an NVA-R661 module of Xethru Inc. The IR-UWB radar system has high spatial resolution because it uses a short pulse signal with a bandwidth above 500 MHz or a fractional bandwidth greater than 0.2 [5] It has higher penetrability than other indoor security solutions, as well as precise location tracking. The and, fabricated quasi-Yagi antenna was fabricated as a quasi-Yagi to improve the bandwidth and connected to an NVA-R661, verifying the validity of the indoor location tracking systems.
