In this article, an open slot split ring resonator (OSSRR) is introduced to realize a composite right/left handed (CRLH) transmission line structure in microstrip technology. The CRLH line is synthesized by etching OSSRR in the ground plane and interdigital capacitor in the microstrip line. Simulated and measured scattering parameter of the structure is presented. The dispersion characteristic ...

In the RF(Radio Frequency) front-end of Beidou navigation system, the high precision filter which filtering some noise of receiving signal plays an important role for the whole system. The designed Filter in this paper is based on the theory foundation of parallel coupled microstrip line band-pass filter which combine the designing method of the traditional filter with microwave circuit simulat...

This paper presents triple band notched ultra wide band (UWB) monopole antenna with overall size of 36 × 32 mm fed by microstrip transmission line. In order to achieve a good impedance matching from 2.7 GHz to 13.4 GHz, a tapered transition between the rectangular patch and the feeding line is utilized. The three notched frequency bands are accomplished by a defected microstrip structure (DMS) ...

─ This paper presents a novel miniaturized parallel coupled-line bandpass filter by etching some slot resonators on the strip for suppressing the first spurious response. These slots perform a serious LC resonance property in certain frequency and suppress the spurious signals. By properly tuning these slot dimensions, multiple closed notches can be generated in the vicinity of spurious harmoni...

Wireless communication has been developed rapidly in the past decades and it already has a great impact on human life. In the field of wireless communications, antennas play a vitally important role. In the late 1970s, there was rapid development in the field of microstrip patch antenna technology. In early 1980s, antenna elements and arrays were developed in terms of design and modeling. Due t...

In this paper, multi-channel capacitive sensor arrays based on microstrip band-stop filters are studied. The sensor arrays can be used to detect the proximity of objects at different positions and directions. Each capacitive sensing structure in the array is connected to an inductive element to form resonance at different frequencies. The resonances are designed to be isolated in the frequency ...

In this paper, design of an aperture-coupled microstrip antenna (ACMSA) using differential evolution algorithm (DE) is described. The classical transmission line model for microstrip antenna is used to determine fitness function for DE and computed results are compared with the results obtained using particle swarm optimization (PSO) and binary coded genetic
