It can provide eight-band operation for Wireless Wide Area Network (WWAN) & Long Term Evolution (LTE), and is also suitable for built-in smart handheld device. The antenna discussed on this thesis is improved from PIFA, its main structure including monopole radiation path, parasitic element & complex parasitic element on PCB board excite with feed-in directly. First of all, main path with monopole antenna can generate 700MHz、1900MHz after adjusted properly. And it also can generate 900MHz、2100MHz with one-quarter waveform parasitic element. To get more bandwidth, complex parasitic element on PCB connected to ground, using coupling effect between two plane, can improve impedance matching of low and high frequency effectively in accordance with requirement of GSM8500、GSM900、DCS1800、PCS1900、UMTS2100、LTE700、LTE2300、LTE2500. The antenna design was using HFSS 3D tool for simulation at first, and then fabricate after simulated result reach the design target. The return loss result fit in with requirement -6dB. At last, this thesis achieve antenna design, 50 ohm made by FR4 PCB excite antenna with feed-in directly. Total size of antenna is 50 x 20 x 1 and has advantage of low cost, simple structure, plane. To compare relative result data, the data between simulation & experiment test is similar, operation band can cover requirement discussed on this thesis. The detail antenna design & experiment test data will be explained & discussed on this thesis. Tsen-Chieh Chiu 丘增杰 2013 學位論文 ; thesis 57 zh-TW |
