Description

Technical Field

[0002] The dipole antenna is a common type of wireless communication antenna, widely used in television, wireless communication, radar and other radio frequency systems. It has a simple structure, is easy to manufacture, and exhibits good performance in different frequency bands.

[0003] The main function of a half-wave folded dipole antenna is to increase bandwidth and serve as a feed source. It is an irregularly shaped symmetrical dipole antenna, designed by folding a full-wave symmetrical dipole into a narrow, elongated rectangular frame, overlapping the two ends of the full-wave symmetrical dipole, and using the center of the other side as the feed point. This design results in a wider bandwidth for the half-wave folded dipole antenna compared to a conventional half-wave dipole antenna.

[0004] Traditional half-wave folded dipole antennas suffer from unstable phase differences between dipoles and weak current coupling, making the band susceptible to interference and affecting signal stability.

[0005] Therefore, it is necessary to provide a half-wave folded dipole antenna to solve the above-mentioned technical problems. Utility Model Content

[0022] This invention provides a half-wave folded dipole antenna. To reduce interference during use, a double-segment folded dipole is constructed using copper tubing. A sealing block closes both ends of the double-segment folded dipole to form a low-impedance loop. A microstrip feed point offset design is introduced to excite phase difference between the dipoles and enhance current coupling strength.
