Optimization of Impedance Bandwidth of a Stacked Microstrip Patch Antenna with the Shape of Parasitic Patch's Slots
Keywords:
Equivalent circuit, stacked microstrip antenna,, X/Ku bandAbstract
In this paper, a novel configuration of wideband stacked microstrip antenna for X/Ku band is presented and analyzed. By cutting five narrow rectangular and one trapezoidal slot on parasitic patch with different dimensions, the impedance bandwidth and resonance frequency of the proposed antenna is adjusted. Also, the effect of incorporated parallel slots on driven patch is examined based on equivalent circuit of E-shaped microstrip antenna. Antenna characteristics are simulated by CST simulator and far-field radiation patterns of simulated and measured results of an array of the proposed antenna are compared.
