Description

technical field

[0001] The invention relates to a horizontally polarized receiving antenna, in particular to a small horizontally polarized ultra-high frequency slot antenna, which belongs to the field of wireless communication. Background technique

[0002] At present, wireless communication represented by mobile communication is developing rapidly. With the improvement of communication capacity, quality, content and other requirements and the development of integrated circuit technology, the multimedia digital communication method has been paid more and more attention by people. At the same time, mobile reception has become one of the main communication methods because it greatly meets the needs of users. Therefore, higher and higher requirements are also placed on the receiving antenna. For example, Shanghai digital TV has been launched recently, and buses and various cars will be one of the main users. Most of the TV transmission in our country adopts the horizontal po...
