Embodiment Construction

[0021] Referring now to the drawings, in which like reference numerals refer to like components throughout the several views, there is shown in FIG. 1 a concealable antenna system 10 in accordance with a preferred embodiment of the present invention. The concealable antenna system 10 includes an electron emitting member in the form of, for example, a sheetantenna 12 . It is meant that the electron-emitting member can be broadly understood as basically any emitting member in the form of a film, which is foldable or expandable, and which enables it to operate at frequencies such as HF, UHF and microwave Communicates with wireless devices (not shown) such as EAS or RFID tags. Also included in the system (not shown) are suitable electronics that are well known and commonly available. The power source 14 supplies electric power to the electron emission member 12 . In addition, a power source may supply power to the electron emission member 12 that is retracted and deployed. As c...

Abstract

A stowable antenna system for a security system is providing which includes an electronic radiating element in the form of a furlable flexible sheet, a power supply to power the electronic radiating element and a housing to receive and store the radiating element in a furled condition. The radiating element may be extended to an unfurled condition for use in the security system. One or more risers may extend from the housing for supporting the radiating element in the unfurled condition. The electronic radiating element may be received in the housing and stored in the housing in a rolled up, windowshade configuration.

Description

technical field [0001] In general, the present invention relates to electronic surveillance systems such as Electronic Article Surveillance (EAS) or Radio Frequency Identification (RFID) systems for detecting the presence of an anti-theft tag within an anti-theft zone adjacent to the system antenna, and more particularly , relates to an improved structure of an antenna system which is portable and has the secondary feature of being provided with interchangeable indicia for advertising etc. purposes. Background technique [0002] Various electronic merchandise surveillance systems have been adopted and implemented to limit the unauthorized removal of merchandise from a particular location. One common form is an electronic merchandise surveillance system that has been placed near exits from retail establishments, libraries, and the like. However, in other applications, electronic article surveillance systems are also used in process control and inventory control to track merc...
