This paper presents a multi-band circular microstrip patch antenna with annular slots and feeding line structure for 5G wireless devices and mm-wave ap¬plications. The proposed design is a tri-band resonating at 40.05 GHz, 49.69 GHz and 63.37 GHz. To improve the antenna bandwidth and gain further, two annular slots are inserted to the circular radiating patch. The proposed structure is imple¬mented on FR-4 epoxy dielectric substrate material with a relative permittivity (ɛr) = 4.4, a height (h= 0.508 mm and a tangent loss (tan δ) = 0.02. A parametric analysis is carried out in order to achieve the optimum gain and bandwidth. The total radius of the optimized circular patch is 1.8 mm and the overall antenna size is 8× 7.6× 0.508 mm3. The achievable fractional bandwidths are 6.64%, 20.4% and 11.72% of the tri-bands operating frequencies respectively. Moreover, simu-lated peak gains of 5.21 dBi, 5.23 dBi and 7.67 dBi are achieved at resonant fre¬quencies 40.05/49.69/63.37 GHz respectively. The proposed micro strip patch an¬tenna was designed, simulated and optimized using the ANSYS High Frequency Structure Simulator software (HFSS). The proposed antenna is compact in size and provides wide impedance bandwidth and good gain. |
