Introduction to Electromagnetic Compatibility
Although the field patterns are the same, the monopole radiates only half the
power of the dipole: the power radiated out of the half-sphere above the ... Thus
the radiation resistance for the monopole is half that of the corresponding dipole.

Handbook of Antennas in Wireless Communications
2 (5.93) It is concluded that the directivity of a short monopole equals 3, and that
the directivity of a quarter- wavelength monopole equals 2 x 1.64 = 3.28. 5.3.1.3
Practical Aspects The preceding discussion reveals that monopole and dipole ...
The simple monopole point source was introduced in Chapter 2. It is an acoustic
source that leads to an omnidirectional sound field and causes an unsteady
volume outflow of fluid from any surface enclosing the source. A small pulsating ...

A Handbook for EMC Testing and Measurement
The receiving antenna correction factors for a typical commercially available
passive 41 -inch monopole [1] are given in Figure 6.3. An antenna factor of
between 24 and 50 dB must be added to the output voltage to obtain the electric
field ...

The Electrical Engineering Handbook
Monopole antennas, as shown in Figure 6.14, constitute a group of derivatives of
dipole antennas. Here, only half of the dipole antenna is needed for operation. A
metal ground plane (ideally of infinite size) is used, with respect to which the ...

Design of Ultra Wideband Antenna Matching Networks: Via ...
The external monopole, typically either retractable or coiled into a helix (to save
space), used to be the dominant antenna type for mobile phones until it became
all but replaced by internal PIFAs a few years ago. Today, as a result of the latest
...

Figure 10.9 Monopole vs Dipole. 10.5.3 Wire monopoles The monopole is a
variant of the dipole that uses the ground plane to provide the other half of the
antenna. It has half the architecture of the dipole and as such, its self-impedance
is half ...
