Design of a broadband Quasi-Yagi dipole
This report suggest the design, fabrication and testing of a Planar Quasi-Yagi dipole antenna using bow-tie element feed from a Microstrip Parallel Stripline Transition. The antenna is design to operate in the frequency band from 800MHz to 2100MHz with ƒc define at 1450MHz. The bandwidth of the ante...

| Summary: | This report suggest the design, fabrication and testing of a Planar Quasi-Yagi dipole antenna using bow-tie element feed from a Microstrip Parallel Stripline Transition. The antenna is design to operate in the frequency band from 800MHz to 2100MHz with ƒc define at 1450MHz. The bandwidth of the antenna was specified to be about 90%. By incorporate the design of a Planar Quasi-Yagi dipole together with the Bow-tie element, the antenna have the advantages of the directional beam of a Yagi and the wide-band of a Bow-tie.
The analysis of the antenna was performed by using Ansoft High Frequency Structure Simulator (HFSS). After which, the physical antenna is fabricated and tested using Anritsu S332D Site Master. Results between the HFSS simulation and prototype antenna were compared and validated. The radiation pattern of the prototype antenna will also validated using a simple Anechoic Chamber setup. |
