According to the research of miniaturization and broadband of ultra-wide band antenna and mobile antenna, it is found that the structure of UWB antenna can be used in the design of mobile phone antenna. A novel UWB antenna and four multi-band mobile antennas are firstly designed. The mainly innovation content is as follows:1. A microstrip slot type UWB antenna is put forward.With a combination structure of circular and rectangular aperture,the antenna is located in the left position of the circuit board. The physical antenna fabrication got the bandwidth of-10 dB is 2.75-10.05 GHz.2. A mobile antenna is put forward with a combination of circular and rectangular aperture.The UWB antenna structure is applied in mobile antenna design. The antenna size is improved, and the rectangular slot of the open circuit is added on the ground, and the feeding of the bent microstrip line is adopted.The measured result could cover LTE700/GSM850/GSM900/PCS/LET2300/LTE2500.3. A combination of gradient aperture antenna is put forward. The ground loads two gaps that one is a left opening V-shaped gap combined with circular and a linear gradient,the other one is a rectangular narrow gap with right side open.The measured bandwidth could cover GSM850/ GSM 900/DCS/PCS/UMTS/LTE700/LTE2300/LTE2500.4. An antenna loaded U-shaped aperture is put forward. Optimize and fabricate the antenna structure of the bend rectangular bar that is loaded on the right opening terminal.The measured antenna bandwidth could be covered GSM850/DCS/PCS/UMTS/LTE700/LTE2300/LTE2500.5. An antenna loaded a group of rectangular structure is put forward. Wide gap and composite patch load a group of small rectangular step respectively. The physical antenna covers the bands of GSM850/GSM900/DCS/PCS/UMTS/LTE700/LTE2300/LTE2500.The proposed antennas have the advantages of low profile, easy fabrication, wide bandwidth. It can be used in UWB and mobile terminals.
