antennas and Wave module

Task 2 (40 Marks) 1. An antenna is radiating in free space. The mouth is rectangular with the dimension of 6 cmx 8 cm and the operating frequency is 5 GHz. The maximum of the radiation pattern of the antenna is +30 dB, while the maximum of its first side-lobe is -20 dB. The total resistance of the antenna is 80 and the loss resistance is 20, determine the: i. Boundaries of the field regions of the antenna; ii. radiation efficiency of the antenna (10 Marks) (4 Marks) Task 2 (40 Marks) 1. An antenna is radiating in free space.
