A singly-fed dual-band circularly polarized dielectric resonator antenna (DRA) is investigated in this paper. It makes use of the fundamental TE111mode and higher-order TE113mode of a rectangular DRA for the dual band design. The DRA has a square cross section. It is excited by a single micro strip line-fed rectangular slot fed. To generate circularly polarized (CP) fields, two corners of the D...

Micro- and nanocantilevers are increasingly employed as mass sensors. Most studies consider the first flexural mode and adsorbed masses that are either discretely attached or homogeneously distributed along the entire length of the cantilever. We derive general expressions that allow for the determination of the total attached mass with any mass distribution along the cantilever length and all ...

In this paper, a dielectric resonator antenna (DRA) is presented for wireless local area network (WLAN) applications. Here three rectangular dielectric resonators are used as stepped manner. The DRA is excited by microstrip line which is an effective feed mechanism to obtain better radiation. In this design, rectangular shape was used as the dielectric resonator as it offers more option to cont...

A radiation pattern synthesis technique for large planar arrays with active element pattern (AEP) method and fine-grained parallel micro-genetic algorithm (FGPMGA) is presented. Based on the AEP method, the mutual coupling between array elements can be taken into account. Analysis problems of large rectangular and triangular grid planar arrays are divided into small linear array problems. And f...

This paper presents a Neural Network model for the design of Micro-strip Antenna for Ultra wideband (UWB) applications which can be operated in a desired frequency range between 2 GHz to 20 GHz. Artificial neural network based on back -propagation (BP) and radial basis network (RBN) algorithms have been used in designing rectangular patch antenna highlighting the difference between them and the...
