摘要：
In this paper, we resolve two issues of microstrip antennas, which are miniaturization and efficiency behavior. For that, a rectangular patch antenna with 16×18×1.6 mm3 dimensions with dual-band characteristics, was designed, fabricated and characterized. In order to improve the problem of narrow bandwidth in microstrip antennas, we implement in this study the slot technique, allowing us to achieve our purpose. This technique, lead to a good reflection coefficient and VSWR. The characteristics of the fabricated antenna were measured and analyzed by Vector Network Analyzer. The results show two resonance frequencies that define two bandwidths defined by a return loss less than-10 dB and are respectively; 400 MHz at a frequency of 7.47 GHz, and 790 MHz at a frequency of 11.01 GHz. Also, the obtained gain has a good value and it’s very remarkable according to the small size of the structure, with a peak value of 6.1 dBi at 12.5 GHz. The small size and good characteristics enlarged the applications domains of our structure, from telecommunications and especially Radar, satellite communications to medical and wireless applications. © 2018, Advanced Electromagnetics.
