whip antenna

[′wip an‚ten·ə]

(electromagnetism)

A flexible vertical rod antenna, used chiefly on vehicles. Also known as fishpole antenna.

Whip Antenna

an antenna in the form of an asymmetrical dipole made from a rigid metal rod or a large number of metal coils strung on a flexible steel line. The rigid rod may be solid or may consist of several coupled sections. In the USSR, a whip antenna made from metal coils strung on a steel line is known as a Kulikov antenna. Whip antennas made from a shaped metallic strip, a braided wire, or a metal-coated dielectric rod are used less often.

The radiation pattern of a whip antenna in the horizontal plane is circular (see Figure 2 in ANTENNA). Therefore, whip antennas are especially suited for communication between ground-based objects whose relative position changes in time, for example, between mobile radio sets in motor vehicles or tanks.

In view of these circumstances, in order to characterize near ground radio link channels for WSNs in agricultural fields and gardens, Radio Frequency (RF) propagation experiments were done at ISM band 2.4 GHz utilizing RF equipments with BPSK modulated transmitted signals on omni-directional antennas and XBee-Pro ZB S2B transceiver modules with integrated whip antenna. Received Signal Strength (RSS) was observed at agricultural fields, gardens and converted into path loss values and compared with Early ITU Vegetation [15], Weissberger et al.'s and Seybold's results in [16,17] and COST 235 [18] foliage loss prediction models using Matlab simulations.
