Abstract
This paper examines a dual-band, low-cost microstrip patch antenna for Ku and K applications through simulation study. Ansys High Frequency Structure Simulator (HFSS) software is used to do the simulation analysis of the suggested antenna. Using Ansys High Frequency Structure Simulator (HFSS) software, the suggested antenna is constructed and simulated to evaluate several characteristics including reflection coefficient (S11), radiation pattern, gain, and bandwidth. The substrate for the antenna is made of FR-4, which has a relative permittivity of 4.4 and a dielectric loss tangent of 0.02. Using the microstrip feed line technology, the planned millimeter wave dual band antenna is examined at operating frequencies of 13 and 22 GHz. At frequencies of 13 and 22, respectively, the antenna's maximum gain values are 4.81 dB and 4.82 dB in the x-y plane. The suggested material might be a decent substitute.
