## how to use Stripline Loss Calculator?

1. To use the above two calculators for stripline loss, follow these steps:

1. Simple Stripline Loss Formula:

• Enter the length of the stripline in inches into the “Length of Stripline (inches)” input field.
• Enter the attenuation per inch in dB/inch into the “Attenuation per Inch (dB/inch)” input field.
• Click the “Calculate Total Stripline Loss” button.
• The result will be displayed below the button, showing the total stripline loss in dB.

2. Detailed Stripline Loss Formula:

• Enter the frequency in GHz into the “Frequency (GHz)” input field.
• Enter the width of the stripline in meters into the “Width of Stripline (m)” input field.
• Enter the thickness of the substrate in meters into the “Thickness of Substrate (m)” input field.
• Enter the thickness of the conductor in meters into the “Thickness of Conductor (m)” input field.
• Enter the relative permittivity of the substrate into the “Relative Permittivity of Substrate” input field.
• Enter the loss tangent of the substrate into the “Loss Tangent of Substrate” input field.
• Click the “Calculate Total Stripline Loss” button.
• The result will be displayed below the button, showing the total stripline loss in dB.

For both calculators, make sure to input the correct values for each parameter. After clicking the “Calculate” button, the calculated result will be shown in the respective result section.

## Formula to calculate Stripline Loss Calculator

The formula to calculate the total stripline loss ($L$) using the simple formula is:

$L = L_{\text{in}} \times A$

where:

$L \text{ is the total stripline loss (dB)}$ $L_{\text{in}} \text{ is the length of the stripline (inches)}$ $A \text{ is the attenuation per inch (dB/inch)}$

The formula to calculate the total stripline loss ($L$) using the detailed formula is:

$L = L_c + L_d$

where:

$L_c = 8.686 \times f \times \sqrt{\pi \mu_0 \mu_r \sigma} \times \frac{W}{b \times t}$ $L_d = 43.43 \times \tan(\delta) \times \sqrt{\text{er}} \times \frac{f}{c}$

and:

$A = \frac{L_c + L_d}{L_{\text{in}}}$

where:

$L_c \text{ is the conductor loss (dB)}$ $L_d \text{ is the dielectric loss (dB)}$ $f \text{ is the frequency (GHz)}$ $\mu_0 \text{ is the permeability of free space} (4 \pi \times 10^{-7} \, \text{H/m})$ $\mu_r \text{ is the relative permeability of the conductor (usually 1 for copper)}$ $\sigma \text{ is the conductivity of the conductor (S/m)}$ $W \text{ is the width of the stripline (m)}$ $b \text{ is the thickness of the substrate (m)}$ $t \text{ is the thickness of the conductor (m)}$ $\text{er is the relative permittivity of the substrate}$ $\delta \text{ is the loss tangent of the substrate}$ $c \text{ is the speed of light (m/s)}$

## what is Stripline Loss

Stripline loss refers to the reduction in signal strength that occurs as a result of the transmission of electromagnetic signals through a stripline structure. A stripline is a type of transmission line commonly used in electronic circuits for routing high-frequency signals. It typically consists of a conducting strip sandwiched between two layers of dielectric material.

The loss in a stripline can be attributed to several factors, including conductor losses, dielectric losses, and radiation losses. Here’s a brief explanation of these components:

1. Conductor Losses: These losses occur due to the resistance of the metal (usually copper) used as the conducting strip in the stripline. As the signal travels through the conductor, a portion of the energy is converted into heat due to the resistance of the metal.

2. Dielectric Losses: Dielectric losses are associated with the insulating material (dielectric) that separates the conducting strip from the ground plane. The dielectric absorbs some of the signal energy, leading to a reduction in signal strength.

3. Radiation Losses: At high frequencies, electromagnetic signals can radiate energy into space. While striplines are designed to confine signals between the conducting strip and the ground plane, some energy may still be lost through radiation.

Stripline loss is a critical consideration in the design of high-frequency circuits, especially in applications such as RF (Radio Frequency) and microwave systems. Minimizing stripline losses is essential to maintain signal integrity and maximize the efficiency of electronic communication systems.
