A 5.8GHz Slot Antenna with Parallel Slit Loading for 5G Conformal and Wearable Applications

In this paper, a slot antenna with parallel slit structure is proposed for conformal surface and wearable applications. The antenna operates at 5.8 GHz with 450 MHz bandwidth. Prototypes were fabricated on flexible PCB for conformal situations, which demonstrated 3 dBi overall gain. Further simulation with bending along cylinder shape was conducted to evaluate the antenna performance for conformal circumstances. Additionally, a system integrated with a human hand model was created to simulate and evaluate the proposed antenna for wearable applications. Simulation tests from both conformal circumstances and human hand model affirm the feasibility of the proposed antenna for 5G wearable applications.
