In this brief, a compact high isolation filtering power divider (FPD) with wide stopband and wide-band three-port reflectionless operation is proposed. Such FPD consists of trigonometric substrate-integrated defected ground structure (SIDGS) based resonator three absorptive networks. The good performance achieved by using the SIDGS. Meanwhile, networks on common-gate topology capable absorbing ...

The aim of this investigation is to improve the performance of a basic microstrip antenna array using a tree structure patch supplied by electromagnetic coupling. The developed network which contains two subnets, a distribution subnet and a scanning subnet, is considered as a first step to design an adaptive microstrip antenna for UMTS use. The patch distribution structure used in this experime...

Software defined radio implementation is required for LTE radio transceivers. An SDR consists of an rf front end and a digital processor platform DSP. This paper is devoted to the design and implementation of the passive part of the front end; the antennas and bandpass filters. It presents the design of two microstrip patch antennas and a third order parallel coupled band pass filter with defec...

A small size ultra-wideband (UWB) antenna having dimensions of 12x 19 mm 2 incorporated with dual bandrejected properties and good gain is recommended in this paper. The recommended antenna consists of a microstrip line fed rectangular-shaped patch with a circular slot on one side of FR4 substrate and rectangular DGS (Defected Ground Structure) on the other side. By etching a circle on the patc...

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 compact and sharp-rejection ultra-wideband (UWB) microstrip band-pass filter (BPF) is developed using of left handed metamaterials realized by complementary split ring resonator (CSRR). Moreover, proposed structure consists of two doublets parallel coupling gaps at each side of a microstrip ring. In comparison with some other filters, this structure shows a significantly wider passband due to...
