Characteristic mode analysis of millimeter-wave series patch array

Aliakbari Abar, Hanieh LU orcid and Lau, Buon Kiong LU (2022) p.225-226
Abstract
In this paper, characteristic mode analysis is used to gain insight into the operation of millimeter-wave series patch array. It is shown that the series patch array (broadside) mode has lower modal bandwidth and higher resonant frequency than the corresponding mode of a constituting patch element, whereas the other dominant orthogonal (broadside) mode is identical between the array and the single element. Moreover, it is found that unlike the use of shorting vias, non-shorted microvias along the array direction can help to decrease the resonant frequency of the series array mode. A parametric study is performed to show the effect of the length and position of the microvias on the series array mode.
