This method takes advantage of the adjustable radiation angle of the phased array antenna to scan the surveillance region in turns. By using the statistics of the tags’ number in different.
A SASL steerable phased array antenna may be configured to provide highly accurate interrogation beam direction feedback, enabling identification of a vector through the volume upon.A passive ultrahigh-frequency (UHF) handheld reader has a range of about 10 feet, while a model using a beam-steerable phased-array antenna can interrogate passive tags at a distance of 600 feet or more. A phased array antenna achieves its beam steering capabilities through active phase shifters—devices that require external power—positioned at every radiating node across.
This chapter discusses electronically steered arrays (ESAs), also commonly called phased arrays. These antennas have beams that can be electronically steered in pointing direction or beam shape, without mechanical motion, and accomplished in microseconds.We present a compact, flat-panel phased-array antenna design that beam steers using only mechanical in-plane rotations. We explain the steering mechanism and characterize the beam analytically and numerically.
The proposed millimeter-wave phased array features a compact and simple structure without using active components and can avoid the loss caused by millimeter-wave lumped components. The results indicate a beam-scanning range of ±76° within the frequency band of 26–30 GHz.We demonstrate an on-chip optical phased array fabricated in a CMOS compatible process with continuous, fast (100 kHz), wide-angle (51°) beam-steering suitable for applications such as low-cost LIDAR systems.
This article proposes the design, simulation, fabrication and testing of a beam steerable antenna array using a 4 × 4 Butler Matrix feed network technique. The proposed antenna is developed to operate at the X band frequency range. A new concept for a gradient phase discontinuity metasurface lens integrated with a phased array antenna possessing a broadly steerable beam is presented in this paper. The metasurface lens is composed of a metallic H-shaped pattern and the metallic square split ring can achieve complete 360° transmission phase coverage at 30° phase intervals.
