Abstract

Abstract In this paper, a circular Sierpinski shaped on-chip fractal antenna with defected ground structure (DGS) is presented for Ku-band applications. The fractal and defected ground structure are employed to achieve higher bandwidth for the entire Ku-band (12–18 GHz). The proposed on-chip antenna (OCA) with a footprint area of 4π mm2 offers wide bandwidth of 7.22 GHz (11.94–19.13 GHz) with the resonating frequency of 15 GHz. At the resonating frequency, the designed antenna shows a peak gain of −19.76 dBi and a radiation efficiency of 55.6%. The co-polarization (CP) and cross-polarization (×P) characteristics of the proposed OCA shows good isolation of 18.05 dBi and 17.44 dBi in the two principal planes with ϕ = 0° and 90° cuts respectively. The measured result of the designed OCA prototype shows a good performance over the desired frequency band.
