Problems solved by technology
T.Taga has done research on this kind of antenna, and pointed out that its disadvantages are large size and narrow bandwidth (T.Taga, "Analysis of Planarinverted Fantennas and antenna design for portable radio equipment," in Analysis, Design, and Measurement of Small and Low Profile Antennas, K. Hirasawa and M. Haneishi, Eds., Artech Hourse, Boston, Chapter 5, 1992)
With the rapid development of communication technology, higher and higher requirements are put forward for the broadband and miniaturization of the antenna. However, the performance of the antenna is particularly sensitive to the length of the antenna. reduce, narrow the frequency band

Description
technical field [0001] The invention relates to a planar monopole antenna, in particular to a wide-band planar comb-shaped monopole antenna, which can be used in the field of mobile communication. Background technique [0002] Monopole antennas have the outstanding advantages of simple structure, light weight, omnidirectional radiation, and low cost. The monopole structure installed on the handheld device is used as the antenna unit, such as the planar inverted F-shaped antenna, which has the characteristics of low profile and easy implementation, and has been widely used in mobile communication and other fields. T.Taga has done research on this kind of antenna, and pointed out that its disadvantages are large size and narrow bandwidth (T.Taga, "Analysis of Planarinverted Fantennas and antenna design for portable radio equipment," in Analysis, Design, and Measurement of Small and Low Profile Antennas, K. Hirasawa and M. Haneishi, Eds., Artech Hourse, Boston, Chapter 5, 1992...
