This study is targeted towards designing and analysing the X and Ku bands receiving antenna using the Code Blocks software and Advanced Design System simulation tool for energy harvesting in order to satisfy the energy needs of autonomous wireless sensors on board of geostationary satellite for structural health monitoring of the satellite panels, where weight, cost, size and efficiency are the principal space antenna parameters accounted. The energy harvester generally consists of receiving antenna, which harvests and scavenges the circumambient electromagnetic field and inputs the rectifier in order to power the sensors. In this study, a compact, wideband semi‐ellipse patch antenna backed with defected ground structure is presented. The antenna compactness (186.8 mm 3 ) is obtained by truncating the elliptical patch to form a semi‐ellipse patch without compromising the band of interest which reduces from launching weight and cost. The proposed antenna covers X and Ku bands for voltage standing wave ratio ≤2 with a maximum return loss of 28.75 dB, the efficiency of 95%, the gain of 9.6 dBi and directivity of 14 dBi, which makes the proposed antenna compatible to use with the rectifier in order to satisfy the energy needs of wireless sensors.
