碩士 === 大葉大學 === 電機工程學系 === 106 === This thesisis a novel design of a circularly polarized coplanar waveguide (CPW) feed antenna for WLAN application.
The antenna consists of a CPW feed structure, two square slots on either side of the feed end, and two staggered mutual resonance structures inserted into each square slot. The proposed antenna gives a circular polarization at a center frequency of 2.4 GHz, and the designed antenna size is 30 x 40 mm2.
First design the simplest antenna, the length change on the reflection coefficient, find the nearest frequency band, and then narrow it so that the reflection coefficient is closer to the target frequency band. To make the matching effect better, and to add a new modality, and found that it is getting closer to the target frequency band, but has not reached the standard (-10db), so the structure is added to make the reflection coefficient reach the standard ‧ through the stepped groove The midpoint etches the longitudinal grooves and adjusts the geometric parameters to form two orthogonal electric fields with orthogonal phase differences to produce circularly polarized waves, so that the reflection coefficient and the axial ratio reach the target frequency band.
