摘要：

This paper presents a low-profile patch antenna with dual-axis wide-beam characteristics. The antenna includes a microstrip patch antenna and four parasitic patch elements. The study demonstrates that both the E-plane and H-plane beams can be extended by strategically placing these parasitic patches. The length and distance of these parasitic patch elements play a crucial role in achieving the desired wide-beam characteristics. A prototype antenna operating at 5.8 GHz is fabricated and measured in an anechoic chamber to validate the concept and design parameters. The measured results confirm the extension of half-power beamwidth in the E-plane to 123 degrees$<^>{\circ }$ (133%) and in the H-plane to 120 degrees$<^>{\circ }$ (153%). This paper presents a low-profile patch antenna with dual-axis wide-beam characteristics. The antenna includes a microstrip patch antenna and four parasitic patch elements. The study demonstrates that both the E-plane and H-plane beams can be extended by strategically placing these parasitic patches. image
