Design and Analysis of Fed Slotted Low Profile Array Antenna for L Band Short-Range Communication and Wireless Applications
摘要
This paper presents a low-profile fed-slotted antenna design for wireless and short-range L-band applications. The goal is achieved with wide bandwidth and precise conjugate matching due to a slotted structure with effective radiation. Design parameters that have been carefully chosen and optimized meet the required standards. The proposed antenna's maximum return loss of 19.8 dB, 25.6% bandwidth, and the minimum axial ratio of 0.15 dB at the resonating notch ensures excellent polarization performance. Extensive measurements confirm the antenna's performance with a Vector Network Analyzer, closely matching the predicted outcomes. The proposed design successfully achieves the desired performance characteristics for L-band short-range communication and wireless applications, as shown by a fabricated antenna prototype that achieves a higher bandwidth percentage of 38.2% with a maximum return loss of 23 dB.
