Effect of Feed Point Position on Metamaterial based Patch Antenna
Microstrip Patch Antennas can be fed by different techniques such as coaxial feeding, microstrip feeding, aperture coupled feeding and proximity coupled feeding. A coaxial feeding technique is used in this paper for feeding patch. CSRR unit is etched on patch to get multiband frequencies. This paper describes effect of change in position of the feed point on patch antenna. The simulations were carried out on CADFEKO 14.0 software. Antenna parameters (reflection coefficient, VSWR, bandwidth, impedance, gain, radiation pattern) were noted for different positions of the feed point. Results were compared for choosing the best feed point position.
