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.

IEE-IERE Proceedings - India, 1971
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.

The slot antenna with coupled dipoles
IRE Transactions on Antennas and Propagation, 1960The problem of an array consisting of a slot antenna and two symmetrically-located cylindrical dipoles is formulated. The approximate distribution of the current along each antenna is obtained by a method of iteration. The radiation function, the coupling coefficients between the slot and the dipole, the relation between the magnetic current in the ...

Antenna factors of an off-resonant dipole antenna
2012 Conference on Precision electromagnetic Measurements, 2012An off-resonant antenna, such as a shortened dipole is widely used in electromagnetic compatibility measurements due to compactness. The antenna factor of the shorten dipole antenna is ordinary calibrated by comparing that of the standard antenna. However, considerable errors are introduced by applying this method with an insufficient separation due to

A plasma receiving dipole antenna
Plasma Physics Reports, 2010Results from experimental studies of a short-wave plasma dipole transceiver antenna are presented. The efficiency of the plasma receiving antenna is estimated, and the optimal frequency range for excitation and reception under the given experimental conditions is determined.

A Modified Magnetoelectric Dipole Antenna
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019This paper proposed an antenna for microwave imaging application, which is based on the concept of a kind of magnetoelectric (ME) dipole antenna. The working band is 1.134.91 GHz, with dimension of 64mm×60mm×46mm and good directivity, which is suitable for use in the application of microwave imaging.

Modeling Earth as a Dipole Antenna
2020 IEEE Green Technologies Conference(GreenTech), 2020The Earth has been represented as a simple dipole antenna to better understand how the electromagnetic field(s) envelopes the Earth and radiates into space. There are three electromagnetic patterns that emerge in my model, which correspond to the far radiative field, the near inductive field and a newly defined magnetoquasistatic field.
