This thesis discuss about the electromagnetic field variation of design and application with miniature chip antenna and patch ceramics antenna, and studies how to adjust the field pattern and the antenna sensitivity, mainly aims at the GPS (1575MHz) miniature chip antenna and patch ceramics antenna, then compared the 3D field pattern in reality application. There are 3 steps at designing: (1) Use electromagnetic numerical simulate software to construct the structure of miniature chip antenna and patch ceramic antenna, and simulate the variation of 3D field pattern and characteristics while it used by single antenna and complete device. (2) Test 3D field pattern of miniature chip and patch ceramic antenna, and then compares the result of simulation and measurement, confirms the accuracy of antenna designing and major point of designing.
Regarding manufacture of chip antenna, it uses the technology of embedded Insert Molding, the method is: Build the circuit of antenna conductor on mother board, then uses the multiple dielectric material, packaged by embedded Insert Molding, and then cuts the individual chip antenna by diamond cutter, finally completes the manufacture of miniature chip antenna.
Regarding patch antenna, it uses low temperature burning ceramic technology, one of multi-layered ceramics piling technology. Because the ceramic material has characteristics with high dielectric and low abrasion, therefore the technology of low temperature burning ceramic has been quoted to the procedure of antenna development. Additionally, the heavy film printing technological develop into technology of low temperature burning ceramic, it takes complicated procedure. In this procedure, the circuit of radiate conductor is printed on ceramic substrate Green Sample with conductible materials, between 2 layers of mother board, drill the connecting aperture for indicated circuit, use halftone printing to fill the aperture to connect the closed 2 layers, achieve 3D antenna structure by intending.
