Benefits to be gained from doing this project. The antenna can operate in two frequency bands within one patch and The antenna can switch the beam more than one direction.
Figure.7 shows comparison of simulated and measured return loss of the antenna that agree well with slightly shift of the response to high frequency due to manufacturing error.
Figure.8 and Figure.9 shows the radiation patterns of antenna when θ=35° at the frequencies of 2.45 GHz and 5.8 GHz, respectively. They confirm that the antenna can provide switched-beam patterns at both designed frequencies.
