An arrow shaped printed antenna for ZigBee applications

An arrow shaped antenna design is presented in this paper for 2.4 GHz ISM band applications. Thess applications include ZigBee [1], [2], Bluetooth [3], WLAN and WiBree. Recently, these applications have been essential for daily use in industrial and home automation in small areas because of their low power profile and long battery life. The proposed antenna is implemented to cover the 2.4 GHz ISM band in which its impedance bandwidth is about 1300 MHz (1.4-2.7 GHz). The antenna is fabricated on FR4 dielectric substrate with dimensions 25×50 mm

. The antenna has an omnidirectional radiation pattern. The measured results are in good agreement with the simulated ones.
