Microstrip line calculator

For a very wide line, w/h≫1, εe=(εr+1)/2+(εr−1)/2=εr, corresponding to the EM energy being confined to the dielectric. For a thin line w/h≪1, εe=(εr+1)/2, the average of the dielectric and air permittivities. The accuracy of Equation (3.5.

How do you make a line in microstrip?

Use Designer, to design in microstrip configuration the transmission line system shown above, using RT5880 dielectric constant εr = 2.22 of thickness, h = 31 mils 2. Assign port #1 impedance as Zg = Z0 ,Port #2 impedance as ZL and Port #3 impedance as ZS 3. Use the values given in the table below for calculations.

What is microstrip in transmission line?

A microstrip is a type of transmission line that consists of a conductor fabricated on dielectric substrate with a grounded plane. It is easily miniaturized and integrated with microwave devices making it a popular choice of transmission line.

What is the structure of microstrip line?

A microstrip transmission line consists of a narrow metallic trace separated from a metallic ground plane by a slab of dielectric material, as shown in Figure 3.11. 1. This is a natural way to implement a transmission line on a printed circuit board, and so accounts for an important and expansive range of applications.

What are the types of microstrip line?

Micro strip lines are of many types such as embedded micro strip, inverted micro strip, suspended micro strip and slotted micro strip transmission lines.

What is the maximum gain of microstrip antenna?

A single patch antenna provides a maximum directive gain of around 6–9 dBi.

Where is microstrip used?

Microstrip is a type of electrical transmission line which can be fabricated with any technology where a conductor is separated from a ground plane by a dielectric layer known as the substrate. Microstrip lines are used to convey microwave-frequency signals.

Which is better microstrip or stripline?

Microstrip circuits are easier (and less expensive) to fabricate than stripline, with less processing steps and easier placement of circuit components. The stripline format affords more isolation between adjacent circuit traces, supporting more densely integrated circuits than with microstrip.

Is microstrip antenna directional?

In high frequency systems, an electric field is used in the coupling, and the antennas used are usually dipole, folded dipole or microstrip antennas. Out of these, dipole and folded dipole antennas are omnidirectional, whereas a microstrip antenna is directional.

What are the losses in microstrip lines?

There are three types of losses that occur in microstrip lines: Conductor (or ohmic) losses in the strip conductor and the ground plane; Dielectric losses in the substrate; Radiation losses.

What is quality factor in microstrip line?

The quality factor is the ratio of stored energy to the energy lost in a resonator circuit. The quality factor of an unloaded resonator is called the unloaded quality factor. The quality factor of a loaded resonator is called the loaded quality factor.

What is dispersion in microstrip?

Abstract: Microstrip transmission lines used in microwave integrated circuits are dispersive. The dispersion of the lines is fully characterized by the frequency-dependent normalized phase velocity VP which is equal to the ratio of guide wavelength λ g to free-space wavelength λ 0 .

What is the disadvantage of microstrip antenna?

Drawbacks or disadvantages of Microstrip Antenna ➨It offers low efficiency due to dielectric losses and conductor losses. ➨It offers lower gain. ➨It has higher level of cross polarization radiation. ➨It has lower power handling capability.

What is bandwidth of microstrip antenna?

Introduction. Microstrip patch antennas, in their conventional form, are narrow-band structures. Their impedance bandwidth is typically 1–2%.

What is the shape of microstrip antenna?

The microstrip patch antenna can have any shape but, rectangular, circular, triangular and elliptical are some common shapes. The radiating patch and the feed lines are usually photo- etched on the dielectric substrate.

What is microstrip array?

A microstrip antenna array is one of the simplest forms of antennas available. The antenna consists of a single printed circuit board with an RF connector and perhaps an absorptive load.

What is a microstrip filter?

At a high level, a microstrip filter is a type of distributed element planar transmission line that is simple to implement in printed circuit boards (PCBs). Composed of a strip conductor, dielectric substrate, and ground plate, microstrip is used in the microwave range with a typical maximum frequency of 110 GHz.

What is surface microstrip?

MICROSTRIP PCB TRANSMISSION LINES For a simple two-sided PCB design where one side is a ground plane, a signal trace on the other side can be designed for controlled impedance. This geometry is known as a surface microstrip, or more simply, microstrip.

What is dBi value?

dBi stands for Decibel Relative to Isotropic Gain. It is the measure of loudness. It is a unit used to express decibels in milliwatts and is often used to measure the strength of the signal in wires and cables.

What is antenna gain formula?

The gain of an antenna G = Antenna efficiency * Antenna directivity D. Units for Gain – dB (decibels), dBi (decibels relative to an isotropic antenna), dBd (decibels relative to dipole antenna)
