A new design of a multiband microstrip patch antenna using slots in the as well defected ground structures (DGS) implemented plane is proposed. Multi resonance response was obtained by etching DGS shapes Traditional operates at 5.2 GHz, which common frequency for Internet Things (IoT) applications. The novel outcome this work compact that resonates three bands, viz. 2.42, 5.22 and 5.92 GHz. Dif...

A new technique to reduce the size, improve the rejection in the stop-band of a low-pass filter using modified defected ground structure (DGS) is proposed. An equivalent circuit model is used to study the DGS characteristics. The parameters are extracted by using a simple circuit analysis method. Several comparisons between the EMsimulations and the circuit simulations of the new structure are ...

Ultra-wideband (UWB) microstrip filter design has been proposed by applying defected ground conductor structures designed with the superformula approach. Simultaneously, effects of materials used in designs on properties have examined. After characteristics determined, carried out AWR program. The structure based an 8 GHz center frequency fifth-order Chebyshev ultra-wide bandpass filter. model ...
