A compact dual-band ram horn-like folded antenna is presented in this work. +e antenna is based on a ram horn-like folded strip, asymmetric microstrip feeding (AMF) technique, partial ground, and protruding stub at the ground plane. +edimension of the proposed antenna is 0.11 λg × 0.17 λg at 2.3 GHz (10 ×15mm2). +e proposed shape is achieved through the combination of two circular arcs with different radii. +e antenna operates at 2.3 GHz and 5.8 GHz with a measured bandwidth of 100MHz and 820 MHz, a gain of 0.62 dBi and 2.2 dBi, and radiation efficiency of 93.67% and 99.87%, respectively. +e prototype of the proposed antenna is fabricated and measured. +e measured result shows a good agreement with the simulated result. +e parametric study of the proposed antenna is performed and results are presented. Besides, a comparative study between the antennas proposed in this work and the state of the art is performed and presented. +e proposed antenna is comparatively small in size than all the recently reported works in the literature while ensuring good radiation characteristics. +erefore, the antenna proposed in this work is a better candidate for future portable sub-6GHz fifth-generation (5G), Advance Long-term Evolution (LTE-A), Worldwide Interoperability for Microwave Access (WiMAX), and Wireless Local Area Network (WLAN) applications.
