چکیده

In this paper we present a cost effective method to fabricate flexible, high density piezoelectric tape, and expl'ore its potential application as a new type of Lamb wave phased array for Structural Health Monitoring (SHM) through simulating the Lamb wave propagation generated from single element and multielement arrays. The piezoelectric tape consists of many patterned and densely packed PZT (lead zirconate titanate) elements sandwiched between two flexible films/foils. The PZT elements can have different shapes and distribution densities and can be addressed individually and/or by groups. The piezoelectric tape phased array can be easily integrated into various mechanical structures and has good conformability to curved surfaces.

تحلیل و طراحی تغییر دهنده فاز N - بیتی MEMS توزیع شده در باند Ka

Modern microwave and millimeter wave phased array antennas are attractive because of their ability to steer wave beams in space without physically moving the antenna element. A typical phased array antenna may have several thousand elements fed by a phase shifter for every antenna, which can steer the resulting array beam to different directions. Their low loss, low cost and lightweight phase s...

Phased array antenna using MEMS phase shifter

This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...
