研究目的
To design a low-profile wideband circularly polarized (CP) omnidirectional antenna with enhanced impedance matching and reduced profile using a capacitive probe fed circular monopole loaded with shorting pins and two sets of branches to improve the axial ratio (AR) bandwidth.
研究成果
The proposed capacitive probe-fed wideband CP omnidirectional antenna achieves a low profile of 0.06λL, with measured bandwidths of 34.6% for VSWR≤2 and 33.5% for AR≤3 dB. The design demonstrates good omnidirectional CP properties and is applicable for modern wireless applications.
研究不足
The study focuses on the design and measurement of a specific antenna configuration, and while it achieves wide bandwidth and low profile, further optimization may be needed for specific applications or to overcome potential fabrication challenges.
