A textile fixed-frequency pattern-reconfigurable coupled-mode substrate-integrated cavity (CMSIC) antenna is designed for wearable applications. By adding metallic snap buttons as switches at the radiation apertures, the resonance frequencies of the odd and even modes can be changed, leading to the reconfiguration of mode and pattern.
A textile fixed-frequency pattern-reconfigurable coupled-mode substrate-integrated cavity (CMSIC) antenna is designed for wearable applications. The H-plane beam directions of the basic CMSIC antenna in the odd and even modes are theoretically deduced. Metallic snap buttons are added at the radiation apertures as switches. Simulations indicate that changing the state of the buttons leads to the shift of the odd- and even-mode resonance frequencies, and thus leads to the mode/pattern reconfiguration at 2.45 GHz. A textile prototype is fabricated using the computerized embroidery and is measured to validate the design. The influences of human body and bending conditions are investigated through simulations and measurements.
