Tunable dipole antennas

Proceedings of IEEE Antennas and Propagation Society International Symposium, 2002
The concept of extending the operating bandwidth of a dipole has been investigated, and two bandwidth extension approaches were studied. The first approach involves the use of parasitic elements to physically change the length of the dipole. The second approach involves capacitively loading a dipole via varactor diodes to produce a travelling-wave ...

3D-fractal rectangular Koch Dipole and Hilbert Dipole antennas

2007 IEEE Antennas and Propagation International Symposium, 2007
3D-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 ...

Subpicosecond photoconducting dipole antennas

IEEE Journal of Quantum Electronics, 1988
Photoconducting antennas have been demonstrated which are capable of generating and coherently detecting subpicosecond electrical pulses. These antennas, when illuminated with femtosecond optical pulses, radiate electrical pulses which have frequency spectra that extend from 2 THz.

Printed Dipole Antenna with Stepped-Width Dipoles

2020 1st International Conference Problems of Informatics, Electronics, and Radio Engineering (PIERE), 2020
The new printed dipole antenna is presented in the paper. The main advantage of the antenna in comparison with classic printed dipole antenna is a small length of dipoles due to their stepped configuration. The antenna works at two central frequencies simultaneously and can be used both as a standalone antenna and as a part of antenna arrays.
