3- The half wave dipole is widely used in more applications compared to other linear antenna lengths,
that is because
a) It has high gain
d) it has small size
b) its easy matching to coaxial 75 Ohm cable
c) low loss
Q2. True or False Questions:
1. In the normal mode, the radiation is perpendicular to the axis of helical antenna.
2. An ideal source in which the power is radiated equally in all directions is called as isotropic radiator.
3. The progressive phase shift of the end-fire array is 90°.
4. The log periodic antenna does not belong to a frequency-independent antenna.
5. The polarization of an electromagnetic wave refers to the orientation of the electric field component of the
wave.
