This chapter focuses on frequency reconfigurable antennas (FRAs). It discusses various
FRAs which are categorized based on how reconfiguration is achieved, and describes the …

This paper presents investigation results on a wideband U-slot loaded modified Eshape
(USLMES) microstrip patch antenna with frequency agile behavior by employing different …

Methods and devices for phase shifting an RF signal for a base station antenna are
provided. The device includes a transmission line that has a stationary ground plane …

Esta dissertação está inserida no projecto R-Meta, Antenas Reconfiguráveis de baixo perfil
utilizando Metamateriais, financiado pela Fundação de Ciência e Tecnologia, FCT e tem …

Reconfigurable and frequency agile antennas are getting popular because they tend to
reduce number of antennas to meet several wireless communication applications on a given …

In this project the design, manufacture and measurement of a broadband patch antenna
excited by proximity coupling is described. The antenna is excited by a coupled microstrip …

Recon gurable antennas are radiating structures that integrate an inner mechanism that
allows the modi cation of its properties (resonant frequency, radiation diagram or …

Re-configurability is one of the key features in modern wireless communications. Indeed, the
increase of services provided imply an optimized management of the electromagnetic …

Históricamente las antenas han sido consideradas como un elemento estático dentro de un
sistema de comunicaciones. En la última década, sin embargo, ha cobrado fuerza el …
