Abstract
ABSTRACT A low profile, small size and lightweight dual-band antenna prototype is presented for satellite application (Ku-band). The proposed design meets the spectrum necessity of region 3 specified by International Telecommunication Union (ITU). The proposed antenna achieves a frequency band of 11.69–13.24 GHz and 13.72–15.07 GHz for direct broadcast service (DBS) and fixed satellite service (FSS) in receive mode, and FSS in transmit mode, respectively. The antenna achieves the impedance bandwidth of 12.29%, and 9.37%, for first, and second band of frequency, respectively. In addition, the axial ratio of 160 MHz (12.30–12.46 GHz) is achieved by the design. The proposed design is fabricated and measured for various parameters such as reflection coefficient, bandwidth, gain and radiation pattern. Moreover, the complexity in realising the design is less due to its single patch and a single layer.
