This article explores the development and fine-tuning of α mm-wave MPA (microstrip patch antenna) featuring silo slots. The starting design parameters are computed using established formulas relevant to patch antenna construction. The antenna is simulated on a substrate with specific material properties, utilizing Rogers 5058 substrate material characterized by a (r) of 2.2 and a tangent-loss of 0.0009. A comparative analysis is conducted to showcase the simulated performance of the presented silo-antenna using HFSS with its equivalent circuit model implemented in AWR. This involves meticulous adjustment of components to achieve the desired characteristics. The article traces the evolutionary phases of the antenna's design, highlighting geometric modifications and alterations to the ground plane. Further, it elaborates on the resonant frequencies of the antenna and offers a comparative assessment of the S11 parameter between AWR and HFSS simulations, revealing strong agreement. The proposed antenna maintains an attractive size of 14 mm x 12 mm and it operates at dual operating bands resonating at 28.1 GHz and 37.9 GHz. Variations in gain for different design iterations are scrutinized and finally the peak gains of 5.2 dBi and 6.5 dBi are attained for the suggested antenna at the operating frequencies of 28 and 37.9 GHz, respectively along with desired radiation patterns in E and H planes at distinct frequencies. The suggested antenna is suitable for 5G applications supporting 28/38 GHz bands in mm-wave spectrum.
