A Double U-Slots Microstrip Antenna for Triple-Bands Operation
In this paper, a design of double U-slots microstrip antenna with triple bands operation is presented. The antenna geometry is fed with a coaxial line feed technique. The feed is connected between the two arms of U-slots. The two slots are created on patch which is placed on the dielectric substrate of FR4 material with the overall dimensions of 74x67x1.6mm. The proposed antenna geometry's performance is investigated in the frequency range of 5GHz to 10GHz. This geometry exhibits three resonances at 6.64GHz, 8.21GHz and 9.18GHz.
