Abstract

An influx of research has been devoted to use different di-electric substrate materials for antenna miniaturization. Design of A modified W-shaped ka band antenna on Al 2O 3 ceramic substrate is presented in this paper. The W shape is obtained from slotted conventional rectangular shaped patch. The ceramic substrate made with Aluminum oxide (Al 2O 3) with high dielectric constant and 1.5 mm thickness and the 3.3 mm × 5.5 mm patch is introduced for antenna miniaturization. The finite element method is employed to design and analyze the presented antenna and result shows that the impedance bandwidth (VSWR ≤ 2) of the proposed antenna is 1.23 GHz (20% of entire Ku-Band). The proposed miniaturized antenna is also able to obtain the stable radiation performance with maximum gain of 4.89 dB in the operating frequency band of 16.7 GHz to 17.95 GHz. The projected antenna is designed and simulated by using Ansoft's 3D full-wave electromagnetic field software HFSS and obtained return loss is below -10dB from 16.7 GHz to 17.9 GHz.
