Contemporary mobile units utilize several standardized internal antenna architectures: Frequently used in wearable devices and for satellite
Often etched into the metal bezel of modern smartphones to save internal space. Antennas for portable devices
Antenna design for portable devices has evolved from bulky external components to highly integrated internal systems that support multi-band operations such as 5G, Wi-Fi, and GPS. A "complete paper" on this topic typically covers the transition from simple monopole antennas to complex systems and millimeter-wave (mm-wave) arrays . Key Antenna Types in Portable Devices
