Description
Dipoles are one of the simplest but most widely used types of antenna. Hertz used them for his famous experiment. a dipole can be considered a structure evolved from an open-end, two-wire transmission line. A typical structure of a dipole consists of two metal wires which are normally of equal length. The radiation resistance (the real part ofZa in this case) is proportional to the square of the dipole length and inversely proportional to the wavelength squared. The reactance of the input impedance is a function of the radius and length of the dipole. The smaller the radius, the larger the amplitude of the reactance. It is proportional to the wavelength. Its radiation pattern is omnidirectional in the H-plane, which is required by many applications (including mobile communications). Its directivity (2.15 dBi) is reasonable – larger than short dipoles although smaller than that of the full-wavelength dipole. The antenna is longer than a short dipole but much shorter than the full-wavelength dipole, hence it is a good trade-off between the directivity and size. The input impedance is not sensitive to the radius and is about 73 , which is well matched with a standard transmission line of characteristic impedance 75 or 50 (with[i]VSWR
