Description

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