BRIEF DESCRIPTION OF FIGURES

FIG. 1 is a graphic used to explain Fresnel's Equations.

FIG. 2 is a block diagram of an embodiment of an antenna as described herein.

DETAILED DESCRIPTION

As shown in FIG. 2, the present embodiment comprises a harvesting antenna 10, comprising a body 16 with a first 12 and second end 14, wherein the first end 12 is configured to affix to a secondary body 20. The antenna body 16 may be of any length or cross-sectional size or shape sufficient to the purposes described herein.

The antenna body 16 may further comprise one or more sensors 30. These one or more sensors 30 may include one or more selected from the group of a biological lab chip, electrochemical sensor, electrothermal sensor, thermochemical sensor, optic sensor, microfluidic sensor, spectral sensor, gas volumetric sensor, liquid volumetric sensor, and an accelerometer. The antenna body 16 may comprise a single sensor 30, multiple sensors 30 of the same type, or a combination of sensors 30. The sensors 30 may communicate with one another, along with a processor 60, creating logic gates and conditions.

These sensors 30 and antenna 10 are then powered to collect the information required by an end user. The power may come from one or more power sources 40 selected from the group of an external power source, ambient or isotype, harvested/stored power bank, a capacitor with or without regulation, field effect passive, and radar. The power source 40 may power a processor 60.

The antenna body may further comprise alerts and defense features 50. This defense mechanism 50 may be of any type that can be used to alert a user of malfunctioning or tampering of the device 10. The defense mechanism 50 may be a voltage discharge, an audible sound, xenon gas discharge (plasmatic or otherwise), optical or via light, or a radio frequency discharge. The defense mechanism 50 may further be a combination of one or more of these. The defense mechanism 50 may be powered by the same power source 40 powering the sensors 30 and antenna 10, or a distinct power source 40.

The frequencies put off and collected by the antenna 10 and can be calculated via Fresnel's Equations. Fresnel's equations describe the reflection and transmission of electromagnetic waves at an interface. That is, they give the reflection and transmission coefficients for waves parallel and perpendicular to the plane of incidence. For a dielectric medium where Snell's Law can be used to relate the incident and transmitted angles, Fresnel's Equations can be stated in terms of the angles of incidence and transmission.

The equations using the FIG. 1 for variables are as follows

$s-\mathrm{polarized}\mathrm{light}:r_{\perp }=\frac{n_i\cos \left({\theta }_i\right)-n_i\cos \left({\theta }_i\right)}{n_i\cos \left({\theta }_i\right)+n_i\cos \left({\theta }_i\right)}{t}_{\perp }=\frac{2n_i\cos \left({\theta }_i\right)}{n_i\cos \left({\theta }_i\right)+n_i\cos \left({\theta }_i\right)}$ $p-\mathrm{polarized}\mathrm{light}:r_{||}=\frac{n_i\cos \left({\theta }_i\right)-n_i\cos \left({\theta }_i\right)}{n_i\cos \left({\theta }_i\right)+n_i\cos \left({\theta }_i\right)}{t}_{||}=\frac{2n_i\cos \left({\theta }_i\right)}{n_i\cos \left({\theta }_i\right)+n_i\cos \left({\theta }_i\right)}$

Using these equations, along with using Brewster's Angle, the antenna body 16 in combination with a processor 60 can take the received information and harvest ambient energy of the breadth of the electromagnetic spectrum concurrently. In a preferred embodiment, this is accomplished with an antenna body 16 comprising meta materials, conductive inks, and thin films. The process of collection comprises modern additive manufacturing processes, spectral modeling software, computer aided isotropic Mandelbrot fractal pattern printing design and further application of computing and physics.
