- Edge Fed Patch Antenna design starts with most important parameter of Antenna that is the frequency of operation. In this example we will demonstrate how to design a square patch antenna using the equations mentioned above and replicated the design in Advance Design Systems.
- Design parameters and tradeoffs are presented for microstrip antennas. As an example, the size must increase to have it work at lower frequencies. The permittivity should be low for large bandwidth but high to make the patch antenna smaller.
- A patch antenna (also known as a rectangular microstrip antenna) is a type of radio antenna with a low profile, which can be mounted on a flat surface.

- Design of linearly polarized rectangular microstrip patch antenna using ie3d/pso a thesis submitted in partial fulfillment of the requirements for the degree of.
- The first step of designing the array is to design the individual element. For this example, a simple square patch antenna was used (Figure 1), and was created directly in CST STUDIO SUITE.
- Radiation Characteristics Radiated Power: Total power emanating from the antenna. Measurement of radio frequency energy in watts. Directive Gain: Measures the directional properties.
This is true in general. Equation (1) below gives the. Second, the width W controls the input impedance and the radiation pattern (see the radiation. The wider. the patch becomes the lower the input impedance is. The permittivity. Decreasing the permittivity also increases the antenna's. The efficiency. is also increased with a lower value for the permittivity.
The impedance of the antenna. Higher values of permittivity. Particularly in cell phones, the designers are. One technique. is to use a substrate with a very high permittivity. Equation (1) above can be solved for L. Hence, if the permittivity is increased by a factor of 4, the length required decreases by a factor of 2.
Using higher values for permittivity is frequently exploited in antenna miniaturization. The height of the substrate h also controls the bandwidth - increasing the height. The fact that increasing the height of a patch antenna. This is the same principle that applies. Increasing the height also increases the efficiency of the antenna. Increasing the height does. The following equation roughly describes how the bandwidth scales with these parameters.
