Design a fixed beam forming array antenna such that it has a maximum pattern at θD and has undesired pattern at θn.. The antenna array element separation is l/2. Plot the resulting array factor and hence compute all possible antenna parameters antennas. Compare your results for the same array with no weightingThe interference cancelation details are as in last page.Question No. 2 Design a circular polarized microstrip patch antenna. Verify your answer using a CST code and extract the possible antenna parameters in addition to the axial ratio. The operating frequency, the antenna substrate and the polarization method are listed below in last page.
