A Miniaturized antenna for Worldwide Interoperability for Microwave Access and Satellite Applications using Square Patch

Abstract

A multiband antenna with a microstrip feed is implemented. The prototype of patch antenna is designed on dielectric material called Flame Retardant-4 that has permittivity of 4.4. The proposed antenna has a volume of 1000mm3 with a square shaped DGS (defected ground structure) to realize different frequencies. This wraps three varieties of frequencies such as 3.5GHz, 6.8GHz and 9.6GHz which are valid for WiMAX, Satellite Uplink and X-Band applications correspondingly. The planned antenna has shown sensible radiation characteristics at numerous operative bands that are appropriate for multiband operations.
