Compact Antenna Designs for Wearable and Portable Medical SystemAbstract
A button wearable antenna and an Lshape planar inverted F antenna (PIFA) antenna were designed for medical eHealth system. A spiral top button wearable antenna was implemented into the antenna structure to obtain additional inductance. Both simulated and measured reflection coefficients show it can cover both the 2.4-2.5GHz and 5.15- 5.825 GHz ISM bands. Good omnidirectionality was achieved at x-y plane for all three bands. A compact L-shape PIFA antenna was designed and fabricated for laptop wireless local area network (WLAN) application to communicate with wearable antenna. The antenna was formed to L-shape to minimize the ground plane size, so that it can be fitted into the top corners of a laptop display. The effect of the presence of display panel was discussed.
