In recent years, according to the requirements of wireless applications, multiband and low profile patch antennas are desired. In this study, a simple rectangular patch triband microstrip antenna is developed to use for Bluetooth/WiFi applications. The antenna is in the form of rectangular slots with different lengths loaded on the rectangular patch with reduced ground size. FR-4 substrate with 1.6 mm thickness is used as substrate material and annealed copper is used as ground and patch materials. The designed antenna is simulated using CST MWS software program. Microstrip line feeding technique with discrete port is used to feed the antenna. According to the results, S11 parameters of three resonant frequencies can be given as -15.08 dB, -11.88 dB and -24.03 dB at 2.39 GHz, 3.07 GHz and 4.92 GHz respectively. Gain values of the resonance frequencies can be given as follows, 2.25 dBi, 3.76 dBi and 1.92 dBi at 2.39 GHz, 3.07 GHz and 4.92 GHz respectively. Proposed antenna bandwidth can be given as, 197.5 MHz (2.29 GHz – 2.49 GHz) at 2.39 GHz, 116.1 MHz (3.01 GHz – 3.13 GHz) at 3.07 GHz and 266.2 MHz (4.79 GHz – 5.06 GHz) at 4.92 GHz, respectively. Since the designed antenna can work at 2.4 GHz and 5 GHz frequency bands with 2.24 dBi and 2.34 dBi, respectively, IEEE 802.11ac/b/g standards are supported by the antenna. So the proposed antenna can be used for Bluetooth and 2.4 GHz/5GHz WiFi applications.
