Embodiment Construction

[0030] The present invention will be further described below in conjunction with the embodiments and the drawings.

[0031] See figure 1 with figure 2 , The present invention is provided with a double-sided copper-clad dielectric substrate P, the dielectric substrate P is a rectangular dielectric substrate, and its size is 30 mm in length, 32 mm in width, and 1 mm in thickness. The dielectric substrate P uses a dielectric substrate with a relative dielectric constant of 2.25±5%. The dielectric substrate P uses an epoxy resin glass cloth dielectric substrate, and the copper layer on one side of the dielectric substrate P is a bending line microstrip antenna radiation patch (such as figure 1 As shown), the copper-clad layer on the other side of the dielectric substrate P has a fractal photonic band gap structure (such as figure 1 Shown).

[0032] The bending line microstrip antenna radiation patch is provided with 6 transverse arms (11, 12, 13, 14, 15 and 16) and 5 longitudinal ...

Description

Technical field [0001] The invention relates to a microstrip antenna, in particular to a fractal photonic band gap (PBG) bent line microstrip antenna used in an ultra-wideband system. Background technique [0002] In 2002, the US Federal Communications Commission (FCC) announced that the frequency band for ultra-wideband (UWB) communications was defined as 3.1~10.6GHz. This frequency band can be used for wireless local area network (WPAN), as well as for precise ranging, metal detection, etc. use. After the IEEE802.15.3a standard was proposed, the ultra-wideband wireless access technology was further standardized. Ultra-wideband technology has attracted much attention because of its low cost, high data transmission rate, penetrability, and low transmit power. It has become a major research hotspot in wireless communications. [0003] Antenna design and manufacturing technology is one of the core key technologies of the ultra-wideband communication system. The characteristics and ...
