Multilayer organic X-band antenna arrays using Wilkinson power dividers with embedded thin film resistors

A Compact and Lightweight Microstrip Antenna Array with Wilkinson Power Divider for X-band Application at 9.5 GHz

“…For isolation factor analysis, it is expected that a higher isolation factor is obtained in order to achieve a lower mutual coupling [8]- [9]. The simulated S 23 and S 32 (Fig.…”

“…As this study also focus on designing the WPD, a linear array arrangement with parallel series feed is chosen. There are various of research findings [1,8,15] reported that proposed and discussed contradict results for different length of spacings. These certainly shows that the findings do not apply to all cases as different studies referred to various design configuration of antenna.…”

“…For insertion loss analysis, both parameters of S 21 and S 31 ideally should be equal to -3 dB [8]- [9]. From Fig.…”

“…It follows that an array antenna needs to operate along with a compatible and reliable power divider. There have been numerous studies and on-going researches which explore the performance of microstrip antennas [5]- [7] array antennas together with power dividers [8]- [9] and those specifically used for X-band application [10]- [13]. In [14], a ten-element microstrip patch array antenna is shown to operate in the X-band frequency region at 9.5 GHz with a gain and directivity of 16.5 dB and 17.7 dB, respectively.…”
