چکیده
This paper introduces the design of a filtenna for cognitive radio systems. Four varactor diodes, which are inserted in bandpass filter, used to achieve desired tunability. The proposed filter is integrated with wideband monopole antenna. achieved by using two coupled defected ground structure (DGS) resonators and microstrip lines ended stubs. antenna designed operate frequency band from 1.3 GHz 3 GHz. four diodes tune resonance 2.7 2 when capacitance increases 1.55 pF 2.67 pF. performance validated simulation measurements fabricated prototype. Finally, tested Software Defined Radio (SDR) platform bladeRF. transceiver can transmit receive wide range 0.3 up 3.8 GHz, makes it suitable testing reconfigurable filtenna.

متن کاملA flexible radio transceiver for TVWS based on FBMC
In this paper a flexible radio approach for opportunistic access to the television white space (TVWS) is presented. Requirement stems from the coexistence scheme used in this band between opportunistic transmission and TV broadcast signals (or wireless microphones). To ensure nonharmful interference of the TVWS signal on the incumbent services, a high adjacent leakage power ratio (ACLR) is expe...

Enormous growth of wireless applications makes the spectrum scarcity problem worse day by day. Moreover, traditional fixed spectrum assignment policy causes serious spectrum underutilization problem. However, Cognitive Radio that enables opportunity based spectrum access for unlicensed users has recently been recognized as a heartening solution for spectrum scarcity and underutilization problem...
متن کاملCapacitor-loaded split ring resonators as tunable metamaterial components
Transmission through split ring resonator SRR structures loaded with capacitors is investigated both experimentally and numerically. Magnetic resonance frequency m is observed to shift to lower frequencies when capacitors are mounted to the various capacitive regions of the SRR structure. The amount of change in m depends strongly on the place where the capacitors are loaded. The magnetic reson...
متن کاملTunable Filter-Antennas for Cognitive Radio Applications
In this paper, frequency-tunable microstrip antennas, for cognitive radio applications, are proposed. The approach is based on electrically tuning the antenna’s operating frequency by integrating reconfigurable band pass filters into wideband antenna structures. The design of an open loop resonator (OLR)-based bandstop filter, and its transformation to a bandpass filter, are investigated first....
