Antena dwi-jalur menggunakan kabel sepaksi_Maisarah Ahmad Ramli_E3_2005_NI
Antena kabel sepaksi banyak digunakan dalam sistem perhubungan. Walaubagaimanapun pengetahuan tentang ciri-ciri antena kabel sepaksi masih tidak lengkap dan perlu dikaji dengan lebih mendalam lagi. Projek yang dijalankan ini telah mengkaji ciri-ciri utama antena kabel sepaksi iaitu seperti frekuensi salunan, galangan masukan dan corak pancaran. Ini adalah untuk mendapatkan persamaan teori agar antena ini boleh digunakan sebagai dwi-jalur. Dwi-jalur yang dimaksudkan adalah UHF (ultra high frequency) dan GPS (global positioning system). Penyelidikan dilakukan dengan cara menyukat nilai frekuensi salunan bagi model antena kabel sepaksi. Kemudian frekuensi ini diplot bagi melihat perkaitan yang ada. Persamaan telah dapat diterbitkan hasil daripada ujikaji yang dijalankan namun ianya tidakla terlalu tepat disebabkan beberapa faktor. Galangan masukan bagi antena ini juga dikaji. Galangan masukan merupakan parameter penting bagi menilai keupayaan sesebuah antena. Seterusya ciri corak pancaran turut dikaji dimana antena dwikutub setengah gelombang digunakan sebagai pemancar dan antena kabel sepaksi sebagai penerima. _________________________________________________________________________________________ Antenna using coaxial cable is extensively used in communication system. However the knowledge and characteristic about this type of antenna is not complete and therefore a comprehensive research is necessary. This project has examine the main characteristic of this antena such as the resonant frequency, input impedance and radiation pattern. This examine have been done to get the theoretical equivalent so that this antenna can be use as dual band antenna. The meaning of dual band antenna is it can be use in UHF (ultra high frequency) dan GPS (global positioning system). The research is done by measuring the resonant frequency for the model antenna. Then all the frequency data will be plot in graph to find the relationship that exist. The equivalent are successfully been create but it is not exact. The input impedance for this antenna also have been studied. Input impedance is one of the important parameter to know the capability of the antenna. Next are the reseach of the radiation pattern. The half wave dipole antenna will be use as the transmitter while the receiver is coaxial cable antenna.
