Q1 Choose the most appropriate answer. 1- The antenna loss resistance is represented by: a) Radiated power b) stored electric energy c) stored magnetic energy d) heating the antenna structure. 2- The antenna current is uniformly distributed over the antenna elements in the a) Isotropic antenna b) omni-directional antenna c)Hertizian antenna d) both b and c. 3- Circularly polarized antenna can receive a) Horizontally polarized wave b) vertically polarized wave cicircularly polarized wave d) all the above. 4- For a given antenna size, increasing the antenna gain leads to a) Reduce the antenna beam width b)increase the antenna bandwidth c) increase the radiation efficiency d) both a and c. 5- The ideal dipole, short dipole and small loop antenna have the same directivity, that is because they have the same a) Electrical length b)electric field c) normalize field gain.
