1. Frequency Reconfigurable Near-Zero Refractive Index Material for Antenna Gain Enhancement Applications
Abstract In this paper, a planar near-zero refractive index material (NZRIM) consisting of an outer loop with four symmetrical quarter-rings is proposed. The quarter-rings are connected to the outer loop by two symmetrical microstrip lines on the opposite side. The backside of the substrate has mutually central split microstrip lines. By loading adjustable c

2. Synthesis and Mechanical Reconfiguration of Ground Plane Tilted Microstrip Antennas Based on Tetra-Circle Fractals
Abstract A synthesis procedure of a mechanically reconfigurable antenna based on tetra-circle fractal patch elements is presented, enabling to change both resonant frequencies and radiation pattern performance. The antenna geometry reconfiguration is implemented by tilting the ground plane of the microstrip antenna with respect to the fractal patch and subst

3. Antenas e superfícies seletivas de freqüência reconfiguráveis para sistemas de comunicação sem fio
Este trabalho tem como objetivo apresentar como as antenas de microfita e as superfícies seletivas de frequência reconfiguráveis podem ser alternativas para operar em sistemas de comunicação sem fio que necessitem alterar sua frequência de operação de acordo com os requisitos impostos a este sistema ou condições do meio. O propósito central é apr
