研究目的
To propose a new wearable planar inverted F antenna (PIFA) co-designed with the ground plane based on characteristic mode theory for wide matching bandwidth around 433 MHz and 2.4 GHz operating bands.
研究成果
The proposed dual-band PIFA demonstrates wide bandwidth, compact size, and reasonable radiation efficiencies in both bands. The design is robust under bending conditions, making it suitable for wearable applications.
研究不足
The study focuses on the design and simulation of the antenna, with limited discussion on practical deployment challenges or long-term durability under wearable conditions.
1：Experimental Design and Method Selection:
The antenna design is based on characteristic mode theory, focusing on co-designing the antenna with the ground plane to achieve wide bandwidth.
2：Sample Selection and Data Sources:
A prototype was built using a 6 mm thick felt layer as the substrate and a
3：17 mm thick conductive textile sheet for the metallic layer. List of Experimental Equipment and Materials:
