The terminal voltage of a receiving dipole antenna
IEEE Transactions on Antennas and Propagation, 1984The terminal voltage of a receiving dipole antenna is dependent on the antenna current distribution which in turn is dependent on its feed-point load impedance.

3D-fractal rectangular Koch Dipole and Hilbert Dipole antennas
2007 IEEE Antennas and Propagation International Symposium, 20073D-fractal rectangular Koch dipole and 3D-fractal Hilbert dipole antennas made of wires are introduced. Theses antennas exhibit lower resonant frequencies and small volume occupations. The performance characteristics of the proposed antennas are examined and compared with successive iterations for the same antenna height for the 3D-fractal rectangular ...

A generalized crossed dipole antenna, the Fourtear antenna
IEEE Antennas and Propagation Society Symposium, 2004., 2004A generalized form of a crossed dipole antenna, the Fourtear antenna, has been designed and tested. The Fourtear antenna is a promising dual-polarized broadband antenna element. The antenna consists of four identical teardrop elements, but the horizontal elements are positioned perpendicular to the vertical elements. The radiating element is printed on

Experiments with dipole antennas
European Journal of Physics, 2009Employment of a data-acquisition system for data collection and calculations makes experiments with antennas more convenient and less time consuming. The determined directional patterns of the dipole antennas of different lengths are in reasonable agreement with theory.

Advantages of the diamond dipole antenna as an active antenna are presented. Such an antenna is like an inverted bow-tie antenna, but the former has some advantages over the ordinary bow-tie antenna. It is shown that the diamond dipole antenna may be an effective element of a new antenna array for low-frequency radio astronomy as well as a ...

Orthogonal infrared dipole antenna
Infrared Physics & Technology, 2008A dual-dipole structure is demonstrated at 10.6 μm, which facilitates electronic cancellation of the non-antenna-coupled thermal response of an infrared antenna-coupled bolometer. Structures of this type may also find utility in high-spatial-resolution measurement of Stokes parameters of a beam of radiation.

A centre-fed dipole antenna with one arm inclined through an angle α1 to its axis (which lies along Z axis) in Y-Z plane and the other arm inclined by an angle α2 in X-Z plane is analysed. The far field analysis predicted that the radiated far field is multipolarised with E vectors along X, Y and Z axes.

In this chapter we will study some simple dipole type configurations that can provide a broader bandwidth: the cylindrical dipole and biconical antenna. In addition, the chapter introduces the folded dipole antenna, which can provide better matching characteristics than that of the single dipole.
