A combination of lowpass and dual band bandpass filter with improved selectivity is presented in this manuscript. Two circular split ring resonators which are connected at the upper side, provide a characteristics. In order to achieve combined passband response two L-shape stubs incorporated into structure. The parametric analysis proposed has been carried out using CST microwave studio. numeri...

In this paper, a triple-band printed dipole tag antenna is proposed for RFID application. The tri-band printed dipole antenna is designed at 0.92 GHz, 2.45 GHz and 5.8 GHz using Computer Simulation Technology (CST). In order to achieve triple-band operation, the proposed antenna contains two branch elements, which acts as an additional resonator. The designed antenna was fabricated using Taconi...

A novel single layer, coaxial probe feed compact triple band slotted microstrip patch antenna with modified ground plane for wireless application has been designed and analyzed. The presented antenna, occupying a compact size of 24 × 22 × 1.6mm3, embodies a rectangular slotted patch and a rectangular ground plane modified with open ended step graded slots. The step graded slots are introduced o...
