Design of Tri-Band Microstrip Patch Antenna

Compared with conventional microwave antennas, microstrip antennas are with small size, light weight, simple to manufacture, low cost, and ease of integration, etc. therefore, microstrip antenna has a wide range of applications in communication and radar fields. The antenna have been analyzed and designed by using the -High Frequency Structure Simulator- (HFSS) software. The designed antenna in this paper can achieve triple band performance to simultaneously cover the 1.90GHz, 2.45GHz and 3.20GHz frequency with return loss of -26.0dB, -24.0dB and -18.0dB respectively. The designed antenna application systems include global system for mobile communication (GSM), the wireless area network (WLAN) in the 2.4-GHz (2.4-2.485 GHz) band, global positioning system (GPS), Worldwide Interoperability for Microwave Access (Wi-MAX) as well as global navigation satellite systems (GNSS). Other important areas of applications include biomedical, missiles and much more.
