High-Performance Antenna Design: Measured and Simulated Results at 26-33 GHz

This paper presents a detailed analysis of a proposed antenna operating in the higher frequency band (26-33 GHz). Measured and simulated data for the antenna's reflection coefficient, gain, and axial ratio are shown in Fig. 13. The measured results align well with the simulated ones. The measured impedance matching bandwidth exceeds 23.7% (from 26 to 33 GHz) for a reflection coefficient lower than -10 dB. The simulated gain curve reaches a peak of 19.81 dBic at 28 GHz and dips to 18.05 dBic at 33 GHz. A 3-dB gain bandwidth is achieved within the operating band. Measured results indicate a maximum gain of 20.53 dBic at 29 GHz and a minimum gain of 17.03 dBic at 33 GHz. The measured axial ratio remains below 3 dB across the entire operating band.
