Abstract:
This paper presents the results of simulation and experimental investigations on a locally fabricated patch antenna using a high dielectric ceramic (alumina) substrate. The antenna was designed for a centre frequency of 6.32 GHz within C-Band which was excited using micro-strip line feed. The bandwidth of the simulated antenna was achieved as 66.1 MHz with a return loss of 21.7 dB at the centre resonant frequency. The observed resonance frequency at the centre was found to be 6.32 GHz with a return loss of 37.55 dB for the locally fabricated antenna. The -10 dB bandwidth of the fabricated design was determined as 251 MHz. Impedance presented at central frequency was 51.2 ohm that indicates an outstanding impedance-matching between antenna and feed line. The obtained results indicate that the fabricated antenna is suitable for its applications in C-band.
