Abstract
A novel microstrip magnetic dipole antenna is proposed in this work with an all-metal structure and open-ended stubs. The antenna is designed with an all-metal structure to improve bandwidth and gain. Open-ended stubs are used to replace the shorting walls of a microstrip magnetic dipole antenna for convenient fabrication. Furthermore, the open-ended stubs produce additional radiation and enhance the antenna gain. Our analysis shows that each stub can be regarded as a monopole element and the proposed antenna can be regarded as a combination of a monopole array and a microstrip magnetic dipole antenna. The proposed antenna produces broadside radiation with a peak gain of 13.1 dBi and a bandwidth from 2.38 to 2.51 GHz. The antenna can be easily manufactured because it is built entirely by metal, with no shorting structure. It is promising to provide long-distance transmission for 2.4 GHz WLAN applications.Funding Information
