It is observed that in a particular antenna it is found that the receiving pattern (sensitivity as a function of direction) is having a main lobe, a back lobe, and 14 side lobes. If it is decided to use the same antenna as a transmitting antenna, then the pattern will _______Select one:a. a main lobe, a back lobe, and 10 side lobes.b. a main lobe, a back lobe, and 14 side lobes. c. a main lobe, a back lobe, and 12 side lobes.d. a main lobe, a back lobe, and 7 side lobes.
