Design of polarization switching microstrip patch antennas using LTCC for 60GHz
碩士 === 國立臺灣大學 === 電信工程學研究所 === 101 === This thesis developed a V band microstrip patch antenna that can switch polarization direction. With a phase shifter that can generate 0o, 90o, -90o and 180o phase shifts, this antenna can achieve four linear polarizations at 0o, 45o, 90o and 135o directions in...

With a phase shifter that can generate 0o, 90o, -90o and 180o phase shifts, this antenna can achieve four linear polarizations at 0o, 45o, 90o and 135o directions in the far field.

In this thesis, we use Kyocera LTCC process to realize the microstrip patch antenna with feed line in the middle layer, and increase the bandwidth by parasitic elements. A coupler connected with a two port microstrip patch antenna can generate left and right circular polarization, and four directions (0o, 45o, 90o, 135o) of linear polarization are synthesized by 0o, 90o, -90o and 180o phases. The antenna size is μm3 and measured realized gain is about 8dB. The design process, measured simulation results, radiation patterns and reflection coefficient are all presented in this thesis. 盧信嘉 2013 學位論文 ; thesis 90 zh-TW |

In this thesis, we use Kyocera LTCC process to realize the microstrip patch antenna with feed line in the middle layer, and increase the bandwidth by parasitic elements.
A coupler connected with a two port microstrip patch antenna can generate left and right circular polarization, and four directions (0o, 45o, 90o, 135o) of linear polarization are synthesized by 0o, 90o, -90o and 180o phases.
The antenna size is μm3 and measured realized gain is about 8dB. The design process, measured simulation results, radiation patterns and reflection coefficient are all presented in this thesis.
