Problems solved by technology

However, for a working antenna, the measured maximum / minimum return loss is generally within the normal range and does not possess a unique characteristic suitable for identification purposes
Aside from maximum / minimum return loss, a working antenna typically exhibits random electrical behavior and thus does not have an electronic "signature"

Embodiment Construction

[0018] Refer to the attached drawings figure 1 The illustration shows an exemplary antenna 100 configured with an RLC circuit that generates a unique antenna signature. figure 1 Here, the antenna 100 includes a ground element 102, a radiating element 104, and an RLC circuit 106. The ground element 102 is connected to ground and the radiating element 104 is configured to transmit and receive signals. The RLC circuit 106 connects the ground element 102 and the radiation element 104.

[0019] figure 1 The RLC circuit 106 in is shown as a simple series RCL circuit. As those skilled in the art will know, the RLC circuit 106 can be replaced by other types of RLC circuits. The RLC circuit includes a resistor 108, an inductor 110, and a capacitor 112. In the following discussion, the resistance of the resistor 108 is represented by R, the inductance of the inductor 110 is represented by L, and the capacitance of the capacitor 112 is represented by C.

Abstract

Methods and apparatus are disclosed for manufacturing an antenna (100) with a unique signature and for identifying the antenna (100) using its unique signature. An exemplary antenna includes a radiating element (104) and a grounding element (102) between which a resistor-inductor-capacitor (RLC) circuit (106) is connected. The RLC circuit (106) is designed to generate a return loss profile that serves as a unique antenna signature. The return loss profile of the RLC circuit (106) exhibits resonant frequencies outside the operating bandwidth of the antenna.

Description

Technical field [0001] The present invention relates generally to antennas used in wireless transceivers, and more specifically, to the use of its unique electronic signature to identify the antenna. Background technique [0002] Marking or identifying the source or manufacturer of the antenna generally relies on the external characteristics of the antenna such as shape, size, color, and packaging, or through the use of trademarks or commercial packaging. Due to wear and tear over time, such features or designs may disappear, making identification of the source or manufacturer of the antenna difficult. In addition, antennas used in the field, for example, installed on the top of a wireless tower, do not allow easy access for close inspection of the antenna type. [0003] Reflectometry is a measurement technique that has been widely used to diagnose problems associated with radio frequency (RF) antennas or electronic circuits or devices. For example, reflection measurement can be ...
