You will learn about these antennas in later chapters.
Physical structure Following are the types of antennas according to the physical structure. UNIT I FUNDAMENTALS OF RADIATION Antenna and Wave propagation Syllabusĭefinition of antenna parameters – Gain, Directivity, Effective aperture, Radiation Resistance, Band width, Beam width, Input Impedance. Basic Types of Antennas Antennas may be divided into various types depending upon- The physical structure of the antenna. Ground wave and sky wave transmission are. That is the reason why long and medium wave radio stations use self-radiating, vertical transmitting masts as their antennas.
