研究目的
To extend the bandwidth of a traveling-wave microstrip antenna by feeding from both ends, eliminating the need for a termination element and canceling out the change of aperture distribution due to frequency shift.
研究成果
The center connected antenna structure provides broadband characteristics, especially when using elements with small coupling. The antenna operates in a wider bandwidth compared to other designs, with the C5=20% configuration showing superior performance.
研究不足
The study is based on simulation results, and practical implementation challenges are not discussed. The effect of coupling on array bandwidth is examined, but other potential factors affecting bandwidth are not explored.
