Nonradiating Edges Gap-Coupled Multiple Resonator Dual and Tri-Band Microstrip Antennas
نویسنده
چکیده
A rectangular microstrip antenna for dual band and tri-band is developed using a parasitic technique. Single rectangular microstrip is splitted into multiple resonators along the width and gap coupled to non-radiating edges. The proposed structure gives sufficient separation between the operating frequencies increasing bandwidth for dual band and tri-band. It covers the frequency range from 1900 MHz to 3 GHz covering Universal Mobile Telecommunication System (UMTS, 1920-2170 MHz), Wireless Local Area Network (WLAN, 2400-2483.5 MHz) and low band Worldwide Interoperability for Microwave Access (WIMAX, 2.5 to 2.8 GHz). Simulation results are presented and discussed.

A dual-band bandpass filter with wide and highly attenuated stopbands is designed using parallel coupled microstrip line (PCML) and stepped-impedance-resonators (SIRs). The proposed filter is composed of a pair of highly coupled PCML-SIR structure and a central resonator using a low impedance rectangular microstrip. Initially, the wide dual-band performance is achieved by creating a transmissio...
