This paper presents a detailed study of the design, simulation, and characterization of a 2x4 slotted microstrip patch antenna array. The antenna array is fed by a microstrip transmission line and is designed on an FR4 substrate with dimensions of 130mm×150mm×1.60mm. The antenna is optimized to operate in two different frequency bands, S and C, respectively. The design process of the antenna array involved four iterations, which allowed for an optimal antenna design to be achieved. The proposed antenna exhibits excellent performance, as indicated by its S11 parameter, gain, and VSWR. The S11 parameter, which is a measure of how much power is reflected back from the antenna, is -22.77dB, indicating low levels of reflection and good impedance matching. The gain of the proposed antenna is 8.19dB, which represents the amount of power that is radiated in a specific direction relative to an isotropic radiator. This is a relatively high value and indicates that the proposed antenna has a high efficiency. The VSWR of the proposed antenna is 1.11, indicating good impedance matching and low levels of signal loss. To evaluate the performance of the antenna, S11 parameter, gain plots, and VSWR plots are provided in the paper. These plots demonstrate the antenna's excellent performance in both the S and C frequency bands, making it suitable for a wide range of applications that require high-performance antenna arrays. Overall, the results presented in this paper provide valuable insights into the design and performance of slotted microstrip patch antenna arrays, which could be useful for future research and development in this field.

Important Announcements

All the authors, conference coordinators, conveners, and guest editors kindly check their articles' originality before submitting them to IJCERT. If any material is found to be duplicate submission or sent to other journals when the content is in the process with IJCERT, fabricated data, cut and paste (plagiarized), at any stage of processing of material, IJCERT is bound to take the following actions.
1. Rejection of the article.
2. The author will be blocked for future communication with IJCERT if duplicate articles are submitted.
3. A letter regarding this will be posted to the Principal/Director of the Institution where the study was conducted.
4. A List of blacklisted authors will be shared among the Chief Editors of other prestigious Journals
We have been screening articles for plagiarism with a world-renowned tool: Turnitin However, it is only rejected if found plagiarized. This more stern action is being taken because of the illegal behavior of a handful of authors who have been involved in ethical misconduct. The Screening and making a decision on such articles costs colossal time and resources for the journal. It directly delays the process of genuine materials.
