1- When the HPBW increase, the directivity of the antenna increases.
2- The side lobes do not appear in a loop antenna.
3- In array antennas, when the phase excitation equal O, the end-fire radiation does not exist.
4- The polarization loss factor of a mismatch antenna is PLF=1.
5- The azimuth plane of a directional antenna is a circle.
6- When C=2/0.1 the Loop antennas are considering an electrically small loop antenna.
7- The axil ratio of the circular polarized antenna is AR=1.
8- The current distribution of the small dipole antenna is the triangular variation.
9- The Return Loss (RL) of -10 dB means no reflection from the antenna.
10- The radiation resistance of the 2.5 2 dipole antenna is greater than 22 dipole antenna.
