12.38. A lossless circular aperture antenna has a gain of 15 dB
and overall physical area of 25 cm^2. The frequency of operation is
10 GHz.
(a) What is the aperture efficiency of the antenna (in %)?
(b) What is the power PL delivered to a matched load given that the
power density of the incident wave at the antenna aperture is 30
mW/cm^2? Assume ideal conditions (no losses).

2.32. A base station cellular communication systems lossless antenna has a maximum gain of 16 dB (above isotropic) at 1.900 MHz. Assuming the input power to the antenna is 8 watts what is the maximum radiated power density (in watts/cm?) at a distance of 100 meters? This will determine the safe level for human exposure to clectromagnetic radiation.
