A compact microstrip-line-fed antenna designed by inserting two pairs of strips into a rectangular slot for achieving tripleband operation is proposed. The antenna, which occupies a small size of only 40 × 32 × 1.6mm3, utilizes inserted strips to generate dual band-notched characteristics so that three operating bands are able to be achieved, which range from 2.2 to 2.7, 3.07 to 3.86 and 5.13 t...

In this paper, a 4 × 4 Butler matrix (BM) switched-beam patch antenna array is designed and discussed. The design is developed on a single layer of Rogers material; RO 5880 with dielectric constant 2.2 and thickness 0.254mm.This makes the designed antenna low cost and easy of fabrication. The four rectangular patches fed by inset microstrip lines are connected to the outputs of the BM. The resu...

The first Inverse Low Gain Avalanche Detector (iLGAD) have been fabricated at IMB-CNM (CSIC). The iLGAD structure includes the multiplication diffusions at the ohmic contact side while the segmentation is implemented at the front side with multiple P diffusions. Therefore, iLGAD is P on P position-sensitive detector with a uniform electric field all along the device area that guarantees the sam...

In this paper a novel design of microstrip diplexer and triplexer using open loop resonators is presented. The proposed diplexer if formed by two band-pass filters for the Industrial Scientific Medical (ISM) applications at 5.8 GHz and the WIMAX applications (IEEE 802.16 WiMAX at 3.17 GHz to 4.2 GHz bands). The microstrip triplexer is designed for the Digital Communication System (DCS) at 1.8 G...

Optical-MSSW interaction has received wide interest for realization of thin film devices for optical signal processing at microwave signal frequency. In this paper, a device structure to obtain optical-MSSW interaction in a threedimensional optical waveguide using a multilayered garnet structure is proposed and analyzed. The multilayered structure enables optimization of the waveguide parameter...

Microstrip technology is widely applied for design and implementation of several communication devices such as filters, diplexers, triplexers, multiplexers, couplers, etc. They are utilized to isolate desired signals remove disturbing signals. The layout diplexers triplexers have two, three four ports, respectively. Passive filters at least one pass channel, whereas two channels transmit the si...

A novel microstrip Coupler with Complementary SplitRing Resonator (CSRR) is simulated and fabricated. The CSRR structure in the grounded plane of a conventional microstrip double-line coupler, increases its even mode characteristic impedance. This results in a higher degree of coupling. The results of simulation and measurement show that the new coupler achieves a high degree of coupling (5 dB ...

This paper presents coaxial feed rectangular microstrip patch antenna. A narrow Lshaped microstrip antenna is fed at the corner using a coaxial feed to obtain a LP operation. Experiments are carriedout to investigate its return loss, its radiation and its time domain behavior, which exhibit good radiation pattern. The simple rectangular and compact L-shaped microstrip antenna is simulated with ...

In this paper, an Artificial Neural Networks (ANN) model has been developed to design the multilayer Rectangular microstrip patch. In the design procedure, synthesis ANN model is used as feed forward network to calculate the resonant frequency. Analysis ANN model is used as the reverse side of the problem to calculate the antenna dimension. The network is trained with the data obtained from mea...
