The problem I wanted to solve
In this project, a microstrip antenna designed at 3.48 GHz worked, trying to increase the gain
and demonstrate the results. In order to increase the gain and produced a circular signal some corners at the antenna was truncated. Furthermore, input reflection coefficient is stabilized. When we examine the designed antenna in literature, the gain obtained with slits, cross-sections and slots is increased to 7.14 dB and the input reflection coefficient is adjusted to 16.07 dB.
What is Corners Truncated 4-Element Patch Array With Slots Microstrip Patch Antenna Design?
Microstrip patch antennas can be preferred in many areas such as communication, space vehicles, military, design design washed and low antenna type. Such antennas can be used at a frequency of 100 MHz to 50 GHz. First of all, the advantages of microstrip patch antennas are the small footprint, no space support required, and the production of feeder lines at the same time as the antenna. Advantages of microstrip antennas in GPS systems. In the claims, they are preferred for use in local network areas .
Tech stack
Sonnet Suite 3-D planar Electromagnetic program is used to design microstrip antenna.
The process of building Corners Truncated 4-Element Patch Array With Slots Microstrip Patch Antenna Design
The antenna has a size of 21 mm x 23.2 mm with 4 cut-edge frames and a total of 69.2 mm x 61 mm. It is designed in a box measuring 700 mm x 610 mm and simulated. The edges of the 4 square segments of the antenna presented in Figure 1 are cut and 2 rectangular spaces of 1 mm x 5 mm are used for each
gaps were obtained. In addition to this design, in the connection points of the 4 cut-edge antennas, the recesses are drawn into the antenna by creating 4.5 mm recesses and the return loss is taken to the optimum level.
Challenges I faced
Key learnings
The antenna we have completed drawing and simulation is ideal when considered on a gain-reflection basis. It has a very efficient performance of 3.48 GHz and a 7.14 dB gain. Also the loss of return is near -16.07 dB. In our simulations, air thickness was determined as 8 and insulator thickness was 1.6 mm. At the entrance of the antenna, the impedance is simulated as 52 Ohms. Although the design has a structure similar to today's antenna designs, our simulation results at the stated frequencies and box sizes are positive after fine tuning. Although some parameters have not been fully optimized by their settings, some gain and frequency play have been declined, but this antenna has been stripped of all optimization problems and tested in the best way possible. It is an antenna that promises very healthy results in the nature of our data.
