Dual-Band Operation of a Microstrip Patch Antenna on a Duroid 5870 Substrate for Ku- and K-Bands

الملخص EN

The dual-band operation of a microstrip patch antenna on a Duroid 5870 substrate for Ku- and K-bands is presented.

The fabrication of the proposed antenna is performed with slots and a Duroid 5870 dielectric substrate and is excited by a 50 Ω microstrip transmission line.

A high-frequency structural simulator (HFSS) is used which is based on the finite element method (FEM) in this research.

The measured impedance bandwidth (2 : 1 VSWR) achieved is 1.07 GHz (15.93 GHz–14.86 GHz) on the lower band and 0.94 GHz (20.67–19.73 GHz) on the upper band.

A stable omnidirectional radiation pattern is observed in the operating frequency band.

The proposed prototype antenna behavior is discussed in terms of the comparisons of the measured and simulated results.
