Abstract

The 433 MHz frequency band plays a pivotal role in long-range (LoRa) wireless communication due to its favorable propagation characteristics within the Industrial, Scientific, and Medical (ISM) spectrum. This study investigates and compares the radiation performance of two antenna configurations-circular disk monopoles (CDMs) and vertical monopoles (VMs)-operating at this frequency. Both antenna types are simulated using the Method of Moments (MoM) implemented in MATLAB, with identical ground plane dimensions and material properties to ensure a fair comparison. Key performance metrics, including the two-dimensional (2D) elevation (E-plane) pattern and the three-dimensional (3D) radiation pattern, are analyzed. Current density distribution is smeared in the CDM one, i.e., reduced peaking is evidenced. The findings provide valuable insights into the relative advantages of each monopole structure in LoRa applications requiring directional and omnidirectional radiation characteristics.
