The wave concept iterative process is a procedure used for analyses a planar circuits This method consists in generating a recursive relationship between a wave source and reflected waves from the discontinuity plane which is divided into cells. A high computational speed has been achieved by using Fast Modal Transform (FMT). In this paper we study a patch antenna and multilayer circuits, to determine the electromagnetic characteristics of these structures.

A new compact [Formula: see text] microstrip patch antenna array design for future 5G applications is presented in this paper. The proposed antenna array consists of square slot loaded with four radiating patch elements. The corporate feed network has been implemented for the excitation of the array. The feed line is connected to the square slot patch through a quarter-wave transformer matching network. The proposed array is designed on an FR-4 substrate with a dielectric constant of 4.4, thickness of 1.6[Formula: see text]mm and loss tangent (tan[Formula: see text] of 0.02. It has a compact dimension of 9.590[Formula: see text] 17.802[Formula: see text]. The proposed structure has been designed and simulated by using commercially available HFSS software. The simulated results (reflection coefficient, gain, efficiency, radiation pattern) are verified through the measurement process to confirm the validity of the design concept. The measurement results are in good agreement with the simulated results. The proposed structure resonates at 38.1[Formula: see text]GHz with a [Formula: see text]10[Formula: see text]dB impedance bandwidth of about 3700[Formula: see text]MHz (36.5[Formula: see text]GHz to 40.2[Formula: see text]GHz). The reflection coefficient at 38.1[Formula: see text]GHz is [Formula: see text]34[Formula: see text]dB, with a maximum gain of 7.81[Formula: see text]dB. The proposed square slot loaded patch antenna array is very promising for 5G communications at 38[Formula: see text]GHz band (37–40[Formula: see text]GHz).

Bahan ajar dikembangkan berdasarkan karakteristik siswa, sehingga kompetensi yang ditetapkan dapat dicapai. Secara umum kemampuan pemecahan masalah siswa masih sangat rendah, siswa belum bisa memahami soal, sehingga terkendala dalam menentukan model penyelesaian soal matematika. Penelitian ini bertujuan untuk mendeskripsikan kevalidan, keefektifan, dan respon siswa terhadap bahan ajar berbasis Problem Based Learning berkemampuan pemecahan masalah yang dikembangkan. Penelitian ini merupakan penelitian pengembangan dengan menggunakan model ADDIE yaitu Analysis, Design, Development, Implementation, dan Evaluation. Subjek Penelitan dalam penelitian ini adalah siswa SMA Negeri 1 Meureubo kelas X Mia2 sebanyak 23 siswa. Instrumen penelitian berupa lembar validasi, angket respon siswa, dan tes. Dari hasil uji coba, pada uji coba I dan II diperoleh bahan ajar berbasis Problem Based Learning yang dikembangkan efektif ditinjau dari 70% siswa yang mengikuti tes kemampuan pemecahan masalah memperoleh nilai minimal 75 dan tercapainya ketuntasan belajar tes kemampuan pemecahan masalah  75% dan respon positif siswa terhadap bahan ajar berbasis Problem Based Learning untuk kemampuan pemecahan masalah yang dikembangkan. Teaching materials are developed based on the characteristics of students, so that the specified competencies can be achieved. In general, students' problem solving abilities are still very low, students have not been able to understand the problem, so it is constrained in determining the mathematical problem solving model. This study aims to describe the validity, effectiveness, and response of students to Problem Based Learning-based teaching materials that are problem-solving skills developed. This research is a development research using ADDIE models namely Analysis, Design, Development, Implementation, and Evaluation. The research subjects in this study were 23 students of Meureubo High School 1 in class Mia2 as many as 23 students. The research instruments were validation sheets, student response questionnaires, and tests. From the results of the trials, in the first and second trials obtained teaching materials based on Problem Based Learning that were developed effectively in terms of 70% of students taking the test of problem solving skills obtained a minimum score of 75 and achievement of learning completeness 75% problem solving ability tests and positive responses for Problem Based Learning based teaching materials for problem solving abilities developed.

IPA Integrated is a place for students to study themselves and the surrounding environment applied in daily life. Integrated IPA Learning provides a direct experience to students through the use and development of scientific skills and attitudes. The importance of integrated IPA requires to pack learning well, integrated IPA integration with the preparation of modules combined with learning strategy can maximize the learning process in school. In SMP 209 Jakarta, the value of the integrated IPA is obtained from 34 students there are 10 students completed and 24 students are not complete because they get the value below the KKM of 68. This research is a development study with the development model of ADDIE (Analysis, Design, Development, Implementation, and Evaluation). The use of KPS-based integrated IPA modules (Science Process sSkills) on the theme of rainbow phenomenon obtained by media expert validation results with an average score of 84.38%, average material expert 82.18%, average linguist 75.37%. So the average of all aspects obtained by 80.55% is worth using and tested to students. The results of the teacher response obtained 88.69% value with excellent criteria. Student responses on a small scale acquired an average score of 85.19% with highly agreed criteria and on the large-scale student response gained a yield of 86.44% with very agreed criteria. So the module can be concluded receiving a good response by the teacher and students.
