electromagnetic waves in the same way as the dipole antenna. The radio channel propagation modeling at mm wave frequencies can be realized.

Sharma, D.D., Pradhan, D.K.: An Efficient Coordinated Checkpointing Scheme. Vector potential, Dave of wave equation, Retarded case, Hertizian dipole. These properties will not change though the same antenna is operated as a transmitter or as a receiver. Antenna And Wave Propagation, Google Books. The output impedance of a transmitting antenna and the input impedance of a receiving antenna are equal in an effective communication. Equality in the lengths of both transmitting and receiving antennas is maintained according to the value of the wavelength. The value of maximum effective aperture is same for both transmitting and receiving antennas. the directivities are same whether calculated from transmitting antenna’s power or receiving antenna’s power. Equality of Directivitiesĭirectivity is same for both transmitting and receiving antennas, if the value of directivity is same for both the cases i.e. The radiation pattern of transmitting antenna1, which transmits to the receiving antenna2 is equal to the radiation pattern of antenna2, if it transmits and antenna1 receives the signal. The properties of transmitting and receiving antenna that exhibit the reciprocity are − The properties of antenna being unchangeable is called as the property of reciprocity. Fractal antennas are self-similar antennas in which the basic antenna shape is divided into several smaller parts where each part is the copy of basic element itself, or it can also be designed by repeating the scaled version of basic antenna element iteratively. Fortunately, we need not worry about that. Fractal antennas are known for their small size, high bandwidth, multiband nature and high efficiency.
While using so, we may come across a question whether the properties of the antenna might change as its operating mode is changed. Sharma Deputy Director (Retd.), Antenna Systems Area, ISRO Outstanding Scientist (ISRO). An antenna can be used as both transmitting antenna and receiving antenna. His research interests include antenna engineering, wave propagation, microwave circuits and communication system, and telecommunication.
