This article presents a compact and high-gain novel p-shape triple-band printed monopole antenna. The proposed antenna is made of a p-shaped monopole radiator with rectangular slot etched on the radiating arm. The slots create triband resonance frequencies. The antenna is also integrated with a novel artificial magnetic conductor (AMC) to achieve high gain. The AMC is implemented with a rectangular structure and has zero phase reflection characteristics, which helps to improve the antenna gain. The proposed antenna resonates at 1.18 GHz, 6 GHz, and 9.4 GHz. The proposed antenna has an improved gain of 6.75dBi. The proposed antenna structures are fabricated and measured peak gain, S11, and radiation pattern are compared with the simulation results. The proposed antenna operates at 6GHz for Wi-Fi 6E connectivity, operates at 1.18 GHz for GPS navigation, and operates at 9.4 GHz for automotive radar systems for collision avoidance.
