1. For the patch antenna in Problem 4.7, assume that copper and dielectric losses are negligible. Find the Q and the 3 dB bandwidth of the cavity. Hint: For a dipole antenna of length b, with uniform current along its length, the radiation resistance Rd is given by Rd -1 = {[λ/b]2 + [4/3] [λ/(b + λ)]}/(80π2).

2. For the patch antenna described above, assume that the maximum electric field in the substrate is 9 kV/cm. Calculate the maximum radiated power.
