Abstract:Â
This article presents a design of a miniaturized antenna for modern wireless communication, which is emerging for the last couple of decades. Advanced wireless applications, such as wearable devices are using Wireless Fidelity (WiFi), Bluetooth, or Bluetooth Low Energy (BLE) as the key communication techniques. These communication techniques are operating at the Industrial, Scientific, and Medical (ISM radio spectrum) frequency band, 2.4GHz. This frequency band does not need a license and free to use. In this article, the fabricated Triple Band Microstrip Patch Antenna can be used at 2.37, 3.94, and 5.96 GHz frequencies. The proposed antenna is designed, simulated, and fabricated by using multiple slots of different shapes on a single patch, and they are separated by calculated distances. Improvement in Bandwidth, VSWR (Voltage Standing Wave Ratio), Directivity, Efficiency, and Gain can be achieved by using a microstrip patch antenna. The reflection coefficient of the designed antenna is around -35dB, and VSWR is around 1.03 at 2.37 GHz.
Keywords: Triple Band Microstrip Patch Antenna, Wideband Antennas, Multiband Antennas
