Abstract :
The main objective of this project is to design a spiral antenna at a frequency range between 2.4 to 2.5 GHz. The spiral antenna is fed by a microstrip line and RT Duroid 5870 is used with dielectric constant, epsivr and thickness, tsub of 2.33 and 0.5 mm respectively. For the spiral antenna design and simulation, the Genesys software is utilised. A prototype of a circular microstrip antenna is fabricated and measured. Simulated results like return loss, VSWR and input impedance are compared with those obtained from measurements where good agreements are shown.
