“…Unlike conventional microstrip antennas, the radiation patch and grounding plate of the 3D woven hollow structure microstrip antenna were formed by a conductive grid of interwoven purple copper filament tows, and the size of the gap between the yarns and the thickness of the yarns both affected the size of the interwoven grid and the electron propagation speed of the conductive part. 19 The electric field distribution of the 3D woven hollow structure microstrip antenna, Figure 9(a), the four corners and upper edge of the square patch had the largest field amplitude and the tail end of the 50 V impedance matcher had a relatively large field amplitude. The direction of the electric field emanated from the middle of the edge of the radiation patch and radiated around the perimeter of the radiation patch.…”

With the popularity of 5 G, there is an increasing request for a light, high-performance, and stable structure for wireless communication. To solve the problems of delamination cracking and its own heavy weight of the conventional microstrip antenna, this study used ultra-high molecular weight polyethylene (UHMWPE) filament tows and purple copper filament tows as raw materials to prepare 3D woven hollow structure microstrip antenna preforms on a common loom. Using the prepared preforms for reinforcement and resin as the matrix, the VARTM process was used to prepare a 3D woven hollow structure microstrip antenna with a height of 6.8 mm, a weight of 35 g, and a bulk density of 0.7 g/cm3. The combination of the electromagnetic performance test and HFSS software simulation shows that the antenna has excellent radiation performance with a gain of 7.5 dB and a measured VSWR of 1.25. The mechanical performance test results show that it can withstand a maximum compression load of 2982 N and a maximum bending load of 364 N with no obvious delamination at the fracture. It is light, thin, and load-bearing with excellent radiation performance. There will be great potential in the unmanned field and the space field in the future.
