Abstract

Bluetooth is a protocol used for data transmission in short range communication from fixed or mobile devices. This technology is designed for low power consumption having short range based on low cost transceiver microchip in each device. Bluetooth devices use Radio communication system, so it is possible for these devices to communicate even when they are not in line of sight of each other but residing in the defined range. Like other wireless devices, Bluetooth device needs to have antenna in order to transmit data signals through the air to the destination and receive transmitted signals from the source. In this paper, the antenna has been designed by substrate of Fire Resistance 4 (FR4) material having dielectric constant of 4.4 with a conducting radiating patch on the substrate and a conducting ground plane on the bottom side of substrate. The ground plane has been partially reduced to improve the antenna bandwidth. The antenna has been analyzed in terms of various antenna parameters such as return loss (Db), gain (Db), directivity (dBi) and return loss by Vector Network Analyzer. The antenna has been designed utilizing Microwave Studio (CST) and also fabricated by Network analyzer E5071C. The antenna design is appropriate to be utilized to Bluetooth applications. It has been noticed that the practical outcomes got through analysis the fabricated antenna that matches with the CST simulator outcomes.
