This paper presents a compact sized inset-fed rectangular microstrip patch antenna embedded with double-P slots. The proposed antenna has been designed and fabricated on ceramic-PTFE composite material substrate of high dielectric constant value. The measurement results from the fabricated prototype of the antenna show -10 dB reflection coefficient bandwidths of 200 MHz and 300 MHz with center ...

This paper describes the concept, design, and measurement of a multi-band circularly polarized printed slot antenna with a single microstrip feed line. The antenna design for circular polarization (CP) at 1.5 GHz for GPS, 2.4 GHz for Bluetooth, and 3.75GHz for WiMAX application is given. The proposed antenna also provides a fourth linear polarized band over 5.2 to 6 GHz covering the WLAN band. ...

Combining INS and GPS data by means of Kalman filtering only suppresses sensor noise in a limited frequency band. This paper describes a filtering methodology that allows optimal elimination of the inertial sensor noise over the whole frequency band of interest. It accommodates a model for short-term inertial errors that is especially applicable to ring-laser and fiber optic gyro technologies. ...

In this paper, we propose an integrated Genetic Algorithm with Hill Climbing to solve the matrix bandwidth minimization problem, which is to reduce bandwidth by permuting rows and columns resulting in the nonzero elements residing in a band as close as possible to the diagonal. Experiments show that this approach achieves the best solution quality when compared with the GPS [1] algorithm, Tabu ...
