Normal operation of gas turbines will be affected by deposition on turbine blades from particles mixed in fuels. This research shows that it is difficult to monitor the mass of the particles deposition on the wall surface in real time. With development of electronic technology, the antenna made of printed circuit board (PCB) has been widely used in many industrial fields. Microstrip antenna is first proposed for monitoring particles deposition to analyse the deposition law of the particles accumulated on the wall. The simulation software Computer Simulation Technology Microwave Studio (CST MWS) 2015 is used to conduct the optimization design of the PCB substrate antenna. It is found that the S11 of vivaldi antenna with arc gradient groove exhibits a monotonous increase with the increase of dielectric layer thickness, and this antenna is highly sensitive to the dielectric layer thickness. Moreover, a cold-state test is carried out by using atomized wax to simulate the deposition of pollutants. A relationship as a four number of times function is found between the capacitance and the deposited mass. These results provide an important reference for the mass detection of the particle deposition on the wall, and this method is suitable for other related engineering fields.

“…In a conventional array antenna, each radiation element is fed with a specific magnitude and phase of RF power from a corporate feed network, in which the main feed is split into a number of smaller RF feeding components . Such corporate network relies on a traveling wave along the transmission line and requires a number of quarter‐wavelength transformers, which oftentimes produce spurious undesirable radiation and give low antenna efficiency in addition to manufacturing complexity . On the other hand, such cumbersome power dividers can be eliminated in a feed network where a standing wave is formed.…”

The concept of standing-wave array antennas is presented. In this new array structure, a high-order standing wave is excited to produce a focused beam. To verify the concept in a simple manner, a five-patch microstrip array is considered. A cavity model is used to illustrate the principle of antenna operation. Measured radiation patterns and input impedances agree relatively well with the theoretical values to confirm the concept of a standing wave in the antenna cavity. The bandwidths of the array antenna are about the same as those of a comparable single-patch antenna. The impedance bandwidth of the array structure is 0.9% while the 3-dB gain bandwidth is 2.7%. The aperture efficiency is about 79% assuming the aperture area includes the ground plane. V C 2017 Wiley Periodicals, Inc.
