| Summary: | In microwave communication field, reflector antennas are widely used in high gain
wireless communication systems. The main constrain in reflector antenna design is
the design of an efficient feed. Moreover, various techniques developed to enhance
the gain ofsingle element DRA have limitations such as high cost, design complexity
and fabrication impediments. Therefore, in this research work, the gain of single
element DRA is enhanced by using DRA as a feed for three reflectors. The types of
reflector explored are; flat, box shaped and parabolic reflector. The reflectors are
implemented at the back ofthe CDRA design to reflect the backward radiation and
consequently improving the forward gain of the antenna. The effect of reflectors on
the resonant frequency, impedance bandwidth, directivity gain and backlobe leveliof
CDRA are analyzed by using CST 3D Microwave Studio software. |
