Livestock Feeder-Embedded RFID Antenna Apparatus
First Claim
1. An RFID antenna apparatus comprising:
- an antenna core forming a circular shape with a first end of the antenna core electrically connected to an antenna feed point and a second end of the antenna core also electrically connected to the antenna feed point;
an impedance matching circuit electrically connected to the antenna core;
a coaxial RF connector electrically connected to the impedance matching circuit and an RFID reading device to transmit RF signals;
the antenna feed point containing the coaxial RF connector;
an antenna outer surface made of a pipe or a protective outer skin layer, wherein the antenna outer surface encapsulates the antenna core, the impedance matching circuit, and the coaxial RF connector to provide weatherproofing and other wear-and-tear-related protection to internal components of the RFID antenna apparatus; and
a circular livestock feeder bowl with a sidewall and a livestock feed-containing area, wherein the circular livestock feeder bowl is structurally incorporated and embedded by the antenna outer surface that contains the antenna core, the impedance matching circuit, and the coaxial RF connector.

Abstract
Several embodiments of a novel RFID antenna apparatus that are uniquely structurally integrated with livestock feeder units are disclosed. In one embodiment, a circular antenna apparatus embeds a circular livestock feeder unit by structurally encapsulating or surrounding a perimeter of the circular livestock feeder unit. In another embodiment, a rectangular antenna similarly embeds a rectangular livestock feeder unit by structurally encapsulating or surrounding a perimeter of the rectangular livestock feeder unit. Preferably, the circular or the rectangular antenna apparatus also includes a protective pipe or an outer skin layer that incorporates an RF antenna feed point, an antenna core, an impedance matching circuit, and a coaxial RF connector inside the protective pipe or the outer skin layer. The novel livestock feeder-embedded RFID antenna apparatuses improve accuracy of animal RFID tag reading, while also minimizing tuning time and reinstallation efforts associated with an RFID-based livestock monitoring system.
