Directional Compact Antenna for Wireless Sensor Network at 2.4 GHz

A Wireless Sensor Network (WSN) is a collection of various sensor nodes in a network capable of sharing information via wireless media. The type of antenna used is considered one of the main factors affecting WSN performance. Therefore, this research focuses on designing a directional compact antenna for WSN communication at 2.4 GHz frequency. This research used yagi uda as a patch antenna structure to suit gain and radiation patterns. Then, it was miniaturized using a meander line so that the antenna has a smaller dimension. As a result, this antenna worked at 2.4 GHz with
$60 \text{mm} \times 58 \text{mm}$
dimensions, 20% smaller than the initial dimensions. The parameters resulting from the design simulation were S11 -32.82 dB, bandwidth 210 MHz, gain 7.452 dBi, and directional radiation pattern.
