This study presents a novel ultra-wideband (UWB) planar array antenna for millimeter-wave (mmWave) applications. The design achieves broadband impedance matching, a controllable notch band for interference rejection, and low sidelobe radiation.

Area of Science:

  • Electrical Engineering
  • Electromagnetics
  • Antenna Theory

Background:

  • Millimeter-wave (mmWave) communication systems require antennas with wide bandwidth and high gain.
  • In-band interference is a significant challenge in UWB systems, necessitating effective rejection mechanisms.
  • Low sidelobe levels are crucial for reducing interference and improving spatial resolution in array antennas.

Purpose of the Study:

  • To design and demonstrate a single-band-notched ultra-wideband (UWB) low-sidelobe planar array antenna for mmWave applications.
  • To achieve broadband impedance matching and introduce a controllable notch band for interference rejection.
  • To realize a compact mmWave planar array with combined UWB, notch filtering, and low sidelobe characteristics.

  • A planar dipole antenna element excited by an H-shaped coupling slot for broadband impedance matching.
  • A centrally loaded parasitic patch acting as a half-wavelength resonator to create a controllable notch band.
  • Additional parasitic patches to enhance high-frequency matching without compromising the notch response.
  • An 8x8 array configuration utilizing a Taylor-weighted feed network with microstrip power dividers.

    • Main Results:

    • The array operates from 19.0 to 45.0 GHz with a Voltage Standing Wave Ratio (VSWR) less than 2.
    • A rejection band is achieved from 35.0 to 38.5 GHz, suppressing gain by approximately 5 dB at 37.0 GHz.
    • Peak gain reaches 20.5 dBi in the passband, with average sidelobe levels below -17 dB.

    Conclusions:

    • The proposed antenna design offers a practical solution for mmWave applications requiring ultra-wide bandwidth and in-band interference rejection.
    • The integration of a controllable notch band and low sidelobe radiation in a compact planar array is demonstrated.
    • This design facilitates enhanced performance for future mmWave communication and sensing systems.
