Problems solved by technology

However, when the lowest sensitivity in known systems is required, the gain produced by the antenna must remain the same, which does not seem to be achievable with hitherto known antennas
[0011] Besides slot antennas, other antenna types are either unknown or unsuitable due to their high space requirements

Embodiment Construction

[0045] refer to Figure 1 to Figure 3 An exemplary embodiment of the antenna 10 of the present invention will be described. The same parts bear the same reference numerals.

[0046]The antenna 10 of the present invention comprises, as its main components, an antenna contour board 20, a plurality of circuit boards 50 having control circuits 40 disposed thereon, and a stabilization board 60 which may also carry electronic components.

[0047] figure 2 The antenna profile plate 20 shown in includes two antenna systems positioned orthogonally to each other. The first antenna system comprises a rectangular array of four antenna slots 31 and the second slot system comprises four antenna slots 32 arranged in a crossing arrangement. The antenna slots 32 arranged in a crosswise arrangement are positioned within the rectangle formed by the antenna slots 31 and are substantially aligned on the latter's diagonal.

[0048] As a result, the slot systems nest within each other and thus ...

Abstract

The invention relates to a slot antenna, particularly a transmitter antenna for RFID, having an antenna contour plate (20) with multiple antenna slots (30, 31, 32) and with at least one control circuit (40) for stimulating the antenna contour plate to emit and / or receive electromagnetic radiation. The slot antenna is characterized in that a circuit board (50) with a control circuit is inserted into at least one antenna slot of the antenna contour plate. The invention further relates to a method for RFID using a slot antenna according to the invention.

Description

technical field [0001] The invention relates in a first aspect to a slot antenna and more particularly to a transmitting antenna for RFID according to the preamble of claim 1 . [0002] In another aspect, the invention relates to RFID methods. Background technique [0003] A general type of slot antenna comprises at least one antenna profile with a plurality of antenna slots, and at least one control circuit for causing the antenna profile to emit and / or receive electromagnetic radiation. [0004] The technology for the remote identification of objects and persons via radio waves (radio frequency identification RFID) is used in many different fields. [0005] For example, RFID technology is used in military applications, identification cards, libraries, and especially in the fields of industrial manufacturing and automation. [0006] The ever-increasing number of closely-packed electrical and electronic devices poses a growing number of industrial environmental concerns. ...
