Abstract

This report presents the design and development of an integrated rectangular patch antenna and T-shape resonator filter, which utilizes cascaded techniques. The reduction of the overall design size in front-end subsystems as well as in manufacturing cost was contributed by integrated method. As starting point in developing processes, the basic concept of filter with the characteristics of the circuit transformation of low pass prototype network for filter, antenna and integrated filter and antenna was applied. Then, next procedure applying Chebyshev band pass for filter, antenna and integrated filter and antenna at selected frequency based on single- and dual-band. The final design process were developed using planar structure based on T-shape resonator filter and rectangular patch antenna. Integrated method using coupling technique was developed in order to combined T-shape resonator filter and rectangular patch antenna. There are two software were used in design and development of integrated rectangular patch antenna and T-shape resonator filter. It is Advanced Design System (ADS) software, and CST Studio Suite software. All designs in this project were simulated, manufactured and measured. The experimental result has shown good results with the simulated results. The reduction of the overall size, low in cost, ease to fabricate and the use of standard printed circuit board process were main benefits of integrated rectangular patch antenna and T-shape resonator filter. This prototype of microwave filters is suitable and is an alternative solution for WLAN applications without an addition of external common impedance network on the systems. A study for integrated of filter-antenna with dual-band for 2.4 GHz and 5.8 GHz wireless local area (WLAN) is presented. The proposed integrated antenna system will be consists of a rectangular with notch dual-band and a microstrip dual-band T-shape resonator low pass filter. As expected to be final result, it should capable to provide wider bandwidth, good selectivity, high suppression in the stop band and directional radiation patterns within the two interested frequency band.
