Wireless technology has significant improvement in features enhancement of device applications. It is highly desirable to operate multiple applications from a single device. A compact size antenna is presented for a variety of IoT based applications, such as home automation, surveillance, satellite communication, vehicle tracking, and medical instruments. This article explores an analytical solution of ultra-large band frequency characteristics of a compact size, trident shape, fractal patch antenna. The overall structure has dimension 18 × 12 × 1.6 mm3. This antenna exhibits the multiedge radiating effects of fractal structure with the help of ground optimization technique. The design evolution consists of a performance measure of the antenna with varying characteristics of the EBG patterns with respect to fractal structure. The design is validated by fabricating the antenna on an FR4 (4.2) substrate, and the return loss & radiation characteristics are measured. The measured |S11| has the impedance bandwidth of 1.59–13.31 GHz and sustainable radiation characteristics. This miniaturized antenna is compatible with the GSM, GPS, Bluetooth, Wi-Fi, WLAN, Wi-MAX, ISM, and other UWB spectrums. The gain of the antenna is 2.52 dBi for the complete operating range. Therefore, the proposed antenna is highly compatible with various wireless devices associated with IoT applications.
