This paper introduces a compact patch antenna with ladder-slot configuration designed for wearable applications. The antenna achieves miniaturization through the incorporation of partial ground and slots on the patch. Operating within the frequency range of 1.5 GHz (lower limit) to 3.8 GHz (upper limit), it covers the wireless body area network (WBAN) and the industrial, scientific, and medical (ISM) frequency bands. It’s designed on an epoxy FR-4 substrate with a dielectric constant (r) of 4.4 and a thickness of 1.6 mm, the antenna resonates specifically at 2.4 GHz. This resonating frequency boasts an impressive impedance bandwidth of 2.3 GHz (equivalent to 86.80%), while maintaining a compact size of 0.42 0.40 mm2. Notably, the antenna exhibits remarkable attributes such as high directivity, favorable cross-polarization levels, and efficiency at its resonating frequency. These features position it as a strong candidate for employment in both WBAN and ISM band Internet of Things (IoT) applications. This can be used in Mobile phones, Bluetooth devices, Wi-Fi Devices, wireless communication and Wearable applications. The antenna's small size, cost-effectiveness, omnidirectional radiation pattern, and reliable far-field characteristics make it a promising choice for wearable applications. |
