Antenna Boosters versus Flexible Printed Circuit Antennas for IoT Devices

Antennas should be small enough to fit in the limited space of IoT devices and, at same time, with multi-band operation across several bands as well ensure stability when embedded a device. In this regard, two different technologies are compared: antenna booster and flexible printed circuit antenna. A comparison is addressed from measured results terms efficiency, concluding that despite more than fifty times smaller area, it provides better efficiency frequency range 698–960 MHz 1710–2690 three boards (PCB): big PCB 131 mm × 60 mm, medium 95 42 65 mm. Moreover, depends on mounting process, whereas does not.
