Traditional microstrip antennas have problems with heavy weight and poor gain. In order to reduce the weight of the antenna itself and improve its gain, the preforms of the 3-D woven rectangular hollow structure conformal bearing microstrip antenna (3DWRHS-CB-MA)with different heights were woven from ultra-high molecular weight polyethylene (UHMWPE) filament yarns and copper wires on a common loom through reasonable design. The preform was used as the reinforcement and epoxy resin was used as the matrix, four different heights (2, 4, 6, and 8mm) of 3DWRHS-CB-MA were prepared by vacuum-assisted resin transfer molding (VARTM) process. Finally, the electromagnetic performance was analyzed by high-frequency structure simulator (HFSS) and experimental testing. The results showed that the frequency deviation of the 2 mm height microstrip antenna was minimal; while the 4 mm height microstrip antenna had better gain efficiency and directional diagram compared to others. The 4 mm height microstrip antenna has good radiation performance with a weight of only 35 g which shows that 3DWRHS-CB-MA are potential candidates for future intelligent textile materials and wireless communication fields. Highlights • Weaving with UHMWPE filament yarns and copper wires on common looms. • The preform was used as the reinforcement, and epoxy resin was used as the matrix. • Simulation of electromagnetic characteristics of antennas using HFSS software. • Proving the effectiveness of the electromagnetic simulation model. • Revealing the electromagnetic radiation mechanisms.
