Özet

There are many applications in communication and microwave hyperthermia are desirable where small lateral size and narrow band properties. Circular microstrip patch and the Archimedean spiral antenna were combined to affect positively on the performance of the exited antenna. The design includes the selection carefully of the dielectric material, the radius of circular microstrip patch, the empty space through the turned microstrip spiral, the width of the spiral and the number turns of the spiral. The simulation and the experimental results confirm that the small size of combined spiral and microstrip patch antennas can be operated over a wide range of frequencies. In addition to the techniques that are applied to obtain the results such as directivity, Half-Power Beamwidth, S-Parameters, and stands for Voltage Standing Wave Ratio (VSWR) for the new shape. The outputs are compared and analyzed with a numerical formulation for spiral and patch antennas and measured.
