Dual-Mode Resonant Horizontally Polarized, Asymmetrically Fed Sectorial Dipole for Microwave and Millimeter Wave Applications

2D sectorial dipole‐enabled planar endfire circularly polarized antenna with widened azimuth half‐power beamwidth

“…h = 2.0 mm, 0.022-wavelength, @ 2.40 GHz), and numerically verified by employing Ansoft's HFSS. Other key parameters are given in Table 1, as designed empirically in references [11,12,20].…”

“…The revealed 2D sectorial electric dipole‐based, azimuth beamwidth broadening mechanism can be potentially employed to design PECPAs with both principal‐cut planes widened [19]: A rectangular magnetic dipole radiates a pure E θ ‐polarized wave, a 2D sectorial electric radiates a pure E φ ‐polarized wave, and a symmetrical microstrip line to coplanar stripline (MSL‐to‐CPS) transition [20] is introduced between them. Ideally, the endfire CP radiation can be realized under equal‐magnitude and phase‐in‐quadrature conditions: A paired orthogonal polarized component can be provided by a magnetic–electric dipole with W ≈ λ /4 and L ≈ λ /2 and the quadrature phase can be provided by the transition.…”
