New features include additional modern material to make the text more exciting and relevant to practicing engineers; new chapters on systems, low-profile elements and base station antennas; organizational changes to Make sure the wire is connected firmly to the insulators at both ends of the antenna and, in turn, attach the insulators to a nylon rope. A half-wave dipole antenna consists of two quarter-wavelength conductors placed end to end for a total length of approximately L = /2.The current distribution is that of a standing wave, approximately sinusoidal along the length of the dipole, with a node at each end and an antinode (peak current) at the center (feedpoint): = ,where k = 2/ and z runs from L/2 to L/2. An RF ground system forms an integral part of the operation of a monopole antenna. Monopole antennas used at low frequencies, below 3 MHz, such as the mast radiator antennas used for AM broadcasting, require the radio transmitter to be electrically connected to the Earth under the antenna; this is called a So a monopole mounted over an ideal ground plane has a radiation pattern identical to a dipole antenna. An engineer can make a more informed choice of antenna element, providing a good starting design and thus increasing efficiency. The balanced nature of the ideal circuit ensures that identical current will exist on each side of the dipole.
