Design and Development of Quad-Band H-Shaped Microstrip Patch Antenna for WiFi and LTE Applications

The increasing demand in portable devices with wireless connectivity provides a challenge to design a RF front antenna. Microstrip patch antennas are widely used because they are of light weight, compact, easy to integrate. However the serious problem of patch antenna is their narrow band due to surface losses and large size of patch for better performance. So for the antenna miniaturization and bandwidth improvement H-shaped microstrip patch antenna was used. In this paper proposed a design of small sized, low profile patch antenna for wireless applications. The antenna multiband capability could be achieved by introducing a slot in the rectangular patch portion of h shaped patch antenna. The proposed antenna structure operates at four frequency bands of 2.2 GHz, 2.4 GHz, 2.8 GHz, and 2.9 GHz for WiFi and LTE applications. The performance measures of antenna return loss, voltage standing wave ratio, radiation pattern, gain, directivity and power were measured and tabulated, which shows that the antenna performance was good and results obtained were optimum. The simulation tool used for this design was Advanced Design System (ADS). Key-Words: Microstrip patch, Multiband Antenna, Gain, Return loss, Directivity, Radiation pattern.
