Abstract
In this paper, a compact (32 × 32 × 1.6 mm3), microstrip line-fed based with dual operating band is presented for X-band (8-12 GHz) application and mostly applicable for radar application. The proposed design was drawn on low-cost FR-4 dielectric substrate (ɛr = 4.4, tan δ = 0.02 and h = 1.6) of P-shaped radiating patch and defected ground structure (DGS). The proposed antenna has return loss is below -10 dB at both exhibited bands, and finding that the first operating band has impedance bandwidth is 14.67% (8.40-9.73 GHz), resonating frequency is 8.8 GHz with 3.32 dBi 3D peak gain and second operating band has impedance bandwidth is 8.80% (10.86-11.86 GHz), resonating frequency is 11.53 GHz with 3.27 dBi 3D peak gain are obtained respectively, and peak radiation efficiency of first and second operating band is 86.5% and 83.4% are obtained respectively. The group delay time of the proposed antenna is varying between -0.90 ns to 0.40 ns (< 0.5 ns) and VSWR of the proposed antenna is close to 1 and less than 2 are obtained. The proposed design and model of antenna has been analyzed with HFSS simulation tool.
