Abstract: We can solve electromagnetic problems using two main mathematical tools: vector calculus and differential equations. These tools command the computational electromagnetic domain. However, these tools are not always needed for the realistic modeling of electromagnetic problems. In reality, we are interested in the measurement of scalar quantities in electromagnetics, not vector quantities. Conventional electromagnetic simulation approaches are proving to be more mathematical than physical. Furthermore, the use of differential equations leads us along a different route for modeling fundamental physics. Since computers need discrete formulations, we can’t directly transform continuous differential equations into numerical algorithms. The algebraic topological method is a direct discrete and computationally ambitious technique that uses only physically measurable scalar quantities. This paper simulates a parallel plate capacitor using global variables and calculating and comparing the potentials with the analytical method. The measured results show a good agreement between the analytical and the algebraic topological methods.

Abstract: The development of communication systems for several processes at this time makes the use of the frequency spectrum of cellular communication more and more. Antenna system which is an important component in a communication system that works on more than one frequency, such as a mobile phone that works with a working frequency of GSM frequency of 900 MHz and Bluetooth frequency of 2.4 GHz. The two antennas with different frequencies are expected to have optimal power in active conditions. This study shows the performance and design analysis of the prototype circular microstrip patch antenna using the coaxial probe feeding method at a frequency of 900 MHz, the dipole microstrip patch antenna using the coaxial probe feeding method at a frequency of 2.4 GHz, and the rectangular microstrip antenna operating at two frequencies, 900 MHz and 2, 4 GHz. The type of substrate used is PCB FR4 with a dielectric of 4.4 and h=1.6. The design of this microstrip antenna uses a mathematical approach. The results obtained from measurements at frequencies of 900 MHz and 2.4 GHz have a loss of less than -58.4897 dB and the two microstrip antennas do not interfere with each other, when the microstrip antenna is in a vertical position the transmit power is optimum and there is no interference when the microstrip antenna is in the vertical position. The loop patch and the dipole microstrip patch antenna are activated simultaneously.
