A Compact Sector-slotted Circular shaped Filtenna with Enhanced bandwidth

MANEESHA DWIVEDI, Pramod Kumar Singhal

Abstract


This paper presents the designing, simulation and fabrication of a compact Sector-slotted circular shaped filtenna. A Filtenna is designed by integrating the two-pole Butterworth Bandpass filter and the sector-slotted circular shaped patch antenna. This combination of filter and antenna results into compactness of the microwave components and also enhancing the overall performance of the system. The Sector-slotted circular shaped patch antenna is substituted on second port and second resonator. A filtenna obtains a peak gain of 3.505dB within the passband and wide bandwidth of 546 MHz with return loss of -19.1928 dB operating at 2.45 GHz frequency. The sector-slotted filtenna obtains the better gain response within passband and wider bandwidth. The proposed filtenna design is fabricated and measured with good agreement between simulated and measured results. All the simulation results have been obtained by using Computer Simulation Technology-Microwave (CST-MW) software.
