Summary: This paper proposes a planar wideband microstrip feedline to a slot-line-based patch antenna for high-frequency pattern diversity applications. The antenna consists of two adjacent rectangular patches separated by the ground slots, with a directive patch slot along the edge of the substrate. A compact common feedline-to-slot configuration is used to miniaturize the antenna. The antenna was fabricated and analyzed inside a far-field anechoic chamber. The measured results of the antenna within a frequency range of 8.5 to 11 GHz show good agreement with the simulation. The antenna has a maximum gain of 9.2 dBi and has the potential to be beneficial for beam steering and X-band applications due to its low profile, broad bandwidth, high gain, and good directivity.

Summary: Textile antenna systems and platforms play a crucial role in smart fabric interactive textile (SFIT) systems, requiring energy-efficient, low-profile designs with stable wireless body-centric communication links. This study proposes a wearable coupled-quarter-mode (coupled-QM) substrate-integrated waveguide (SIW) antenna with seamlessly integrated hybrid kinetic and ambient-light energy harvesters. The antenna platform, made of protective rubber foam and copper taffeta, can be seamlessly integrated into protective clothing. Experimental results demonstrate that the integrated antenna platform achieves a wide impedance bandwidth, high radiation efficiency, and maximum gain. Moreover, it can harvest a significant amount of power when worn around a person's wrist in an illuminated room.
