1.5-dim. Positioning and Identification Antenna Outdoor
HG G-98850
This antenna is designed to be used for positioning and/or trackguiding vehicles in rough outdoor environment, as all electronic components are fully sealed as well as equipped with an extended temperature range. All important parameter settings, calibration and updates are carried out via an integrated serial interface.

Operational Description
Antenna HG G-98850-B utilizes a completely new antenna concept, which has a larger reading area with a linear transponder positioning function. The antenna is so-called 1.5 dimensional, meaning that it outputs the Transponder code as well as the linear deviation rectangular to the direction of travel and in addition the information “Crossing of the transponder“.
The transponder antenna has an output format, which enables the user to configure additional system information. This additional information, for example, may be used by an external visualization system (e.g. vehicle control unit with display) and enables statements regarding the condition and availability of antennas and transponders.
As soon as a transponder is within the antenna’s reading range, it is supplied with a non-contact inductive energy field of 128 kHz and then cyclically transmits its code back to the antenna at half the antenna’s transmission frequency. The transponder is otherwise completely passive and does not require its own power supply or battery. Only one transponder may be in the reading range of the antenna at any one time.
The relative transponder position rectangular to the direction of travel is measured.
From this relative position it is not possible to derive a world coordinate system without
further effort due to the fact, that the transponder field is rotationally symmetrical to
the longitudinal axis of the transponder. The internal interpreter decodes the transponder code. Each exceeding of the coordinate axes in direction of travel generates a positioning impulse with adjustable duration.
Due to the measuring principle different signal strengths of transponders and altitude variations of the antenna have hardly any influence on the output signal.
