A New Multi-Resonant Frequency Microstrip Antenna with U-Shaped Patch for Wireless Communication
In this paper, the authors present the investigation of a new square patch antenna. In the designed antenna a U-shaped square patch has been constructed and material substrate is used in the designed antenna for multiple resonances. It is a light weight, low profile, low volume, easily mounted and low fabrication cost antenna. In this proposed antenna, the authors have achieved 4 resonances of -50.40db, -42db, -27.92db and -21.83db at a frequency of 5.21Ghz, 5.98Ghz, 5.55Ghz and 4.36Ghz respectively. The maximum achieved gain of the designed antenna is 7.
