Digitally Excited Reconfigurable Linear Antenna Array Using Swarm Optimization Algorithms

This paper describes the synthesis of digitally excited pencil/flat top dual beams simultaneously in a linear antenna array constructed of isotropic elements. The objective is to generate a pencil/flat top beam pair using the excitations generated by the evolutionary algorithms. Both the beams share common variable discrete amplitude excitations and differ in variable discrete phase excitations...

Equivalent Circuit Model for Square Ring Slot Frequency Selective Surface

An equivalent circuit model for predicting the frequency response of a square ring slot frequency selective surface (SRS-FSS) for normal incidence is described. The proposed FSS consists of an array of square patches centered within a wire grid. The presented circuit model is formed by the impedance of the wire grid that is parallel with the impedance of the patch array, also the mutual couplin...

Reconfigurable Microstrip Patch Antenna for Frequency Diversity Using RF MEMS

Abstract: A novel reconfigurable patch antenna for frequency diversity is proposed by reconfiguring its geometry using tree rectangular tapes that are connected to the patch via six RF MEMS switches. So switching between the different frequency bands is achieved by using capacitive series RF-MEMS switches. The antenna was designed to operate at 2.6 GHz, 3.1 GHz, 3.5 GHz and 5 GHz.

Frequency-Reconfigurable Stacked Patch Microstrip Antenna Using Aperture-Coupled Technique

This paper presents a novel structure of a frequency-reconfigurable microstrip antenna fed with an aperture-coupled technique and stacked patch technology. The proposed antenna design has a unique structure; the radiating elements (top and bottom patch) are sorted in stacked substrate layers to indicate the different operating frequencies. One PIN diode switch integrated at the feedline is reco...
