研究目的
To present a new wideband circularly polarized (CP) antenna with improved impedance and axial ratio (AR) bandwidth through the use of inverted L-shaped slots and end shorting vias.
研究成果
The designed compact wideband CP antenna achieves improved bandwidth through the use of L-shaped slots and end shorting vias, providing equal amplitudes and 90° phase difference between orthogonal components. The antenna operates at 5.8 GHz with high gain and has been validated through simulation and measurement, showing good agreement between results.
研究不足
The paper does not explicitly mention limitations, but potential areas for optimization could include further miniaturization of the antenna and enhancement of gain across the operating bandwidth.
