| Summary: | This thesis will discuss on designing and fabricating an Omnidirectional antenna operating at Very High Frequency for Automated Dependant Surveillance Broadcasting (ADS-B) System. The antenna will resonate at 1090 MHz and was design with mixture of two methods, there are defected ground structure (dumbbell shape at the ground) and fractal shape at the patch antenna. The size of the proposed antenna after completed design phase by using CST-WMS 2015 is 71 mm x 65.52 mm and the resonance frequency of 1090 MHz. The size reduction to 20% from the conventional approach due to the implementation of DGS and Fractal Shape to conventional antenna. This antenna produced an omnidirectional radiation pattern with 1.661 dB gain and 11.42% bandwidth base on simulation result. Agreement between simulated and measured results is provided a better achievement. |
