Compact Wideband Circularly Polarized Antenna with Symmetric Parasitic Rectangular Patches for Ka-Band Applications

Abstract: In this paper, a novel wideband circularly polarized (CP) millimeter wave (mmWave) microstrip antenna is presented. The proposed antenna consists of a central patch and a microstrip line radiator. The CP radiation is achieved by loading a rectangular slot on the ground plane. To improve the 3-dB axial ratio bandwidth (ARBW), two symmetric parasitic rectangular patches paralleled to a central patch and a slit positioned to the right of the central patch are loaded. To verify this design, the proposed antenna is… Show more

“…It is observed from the figures that the radiation pattern at ϕ = 0 0 (E-plane) has no side lobes compared to ϕ = 90 0 (H-plane). This is because, at millimeter-wave frequency bands, the radiation pattern is disturbed because of the increasing propagation modes [15].…”

“…There is a decrease in 3dB gain values and reflection coefficient values as the frequency ranges are increasing except 38.01GHz as shown in Figure 7(a) to (e) and these are summarized in Table 3. The observation was done with radiation performance which is degrading with an increased level of side lobes due to the feeding network [32]. .…”
