연구 분야: Networking

학회: 2023 IEEE International Symposium On Antennas And Propagation (ISAP)

This paper presents a novel leaky-wave antenna based on utilizing the high bandwidth and low loss ridge gap waveguide concept, featuring a cosecant squared radiation pattern. The antenna is designed to operate within the frequency range of 25 GHz to 29 GHz. At the center frequency of 28 GHz, the antenna achieves a maximum gain of 10 dBi. Additionally, at a frequency of 28.8 GHz, the antenna exhibits a maximum return loss of -16.9 dB. Moreover, the proposed leaky-wave antenna demonstrates the potential of the radiation technology for 5G systems by enabling scanning angles ranging from approximately 5° to 20° across the specified frequency range. This feature highlights the versatility and suitability of the antenna for various applications in 5G communication systems.
