Two decades of transesophageal phased array probes.
After its introduction about two decades ago, transesophageal echocardiography (TEE) has rapidly evolved into an important diagnostic feature for the cardiologist, since it offers anatomic and hemodynamic information which cannot be obtained precordially. Part of this success was due to the developments in transducer technology which resulted in smaller probes with progressively better imaging ...
متن کاملPhased 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 ...
متن کاملDirectivity Investigation of two Annular Phased Array Transducers
Abstract Annular phased array transducers are well known in the medical field, with their main use being in ophthalmology and dermatology, and have started to be employed in the NDT industry relatively recently. Annular arrays consist of a centre circular element and multiple ring-shaped elements of different width. This unique geometry of the probe makes it difficult to determine the generatin...
متن کاملA Trinary-Phased Array
A trinary-phased array, in which a phase quantization unit of phase shifters is 120 degrees is examined. The phase quantization unit of 120 degrees is the roughest value in practical phased array applications. Despite its rough phase quantization, the sidelobe level of less than −9 dB is attained by a genetic algorithm approach. key words: phased array, trinary phase shifter sidelobe reduc-
متن کاملPhased Array Feeds
The two open-ended frontiers in radio astronomy instrumentation are collecting area and field of view. Greater collecting area translates directly into greater sensitivity while increased field of view increases observing efficiency and makes feasible new areas of science, such as searches for transient radio sources, rare types of pulsars, and surveys of large portions of our Galaxy and of the...
