An Electrically Small Antenna in Package Design with Embedded Electronics for RPW Detection

Abstract

The tracking and detection of Red Palm Weevils (RPWs) are highly desirable for efficient pest control. Bluetooth Low Energy (BLE) tracking system is a good option for real-time monitoring, however, for mounting the system on the insect, it must be miniaturized, particularly the antenna part. In this paper, we propose an electrically small inverted F antenna which is realized on the BLE system package, qualifying it as an antenna in package (AiP) design. The antenna has been designed with the embedded electronics and has a highly compact size of 0.05\lambda\times 0.05\lambda\times 0.025\lambda$. It is very well matched at 2.48 GHz with 17 MHz bandwidth. It demonstrates a maximum detection range of 300 meters.
