High Permittivity Ceramic- Polymer Composite Substrate for Wearable Antenna Applications

Antenna systems must keep up with ever-increasing requirements and technical difficulties as wireless communications remain relevant. Microstrip patch antennas were chosen for their benefits. This study aimed to simulate various PDMS-Ceramic composites to simulate different permittivity's of potential ceramic polymer substrates and simulate a wearable antenna using the ceramic polymer substrate at 2.45 GHz. Dielectric ceramic-based substrates are excellent prospects for antenna downsizing. Since ceramic-polymer composites have a controllable dielectric constant and a low-loss tangent, they are very suitable for dielectric loading for potential wearable antenna. PDMSFerric Oxide (Fe2O3), PDMS-FR4, PDMS-Aluminum Oxide (Al2O3), PDMS-Barium Titanate (BaTiO3), PDMS-Strontium Titanate (SrTiO3), and PDMS-Mg-Ca-Ti (MCT) of ceramic-polymer have all been investigated in this proposed study. It is also simulated in two designs, which are uncut and cut antennas. Then, the antenna simulation was performed using Computer Simulation Technology (CST) software. All simulations of all prototypes are recorded, compared, and analysed. Both antenna designs have shown a good return loss performance for 2.45 GHz band applications and can be used for the same wireless communications application. The radiation pattern of the cut design patch shows omnidirectional properties.
