“…The switching speed of a PIN diode is in the range of 1-100 nsec (Christodoulou et al 2012). Reconfigurable antennas resorting to PIN diodes (Chen et al 2007;Chen and Row 2008;Kim et al 2008;Wu and Ma 2008;Sarrazin et al 2009;Shelley Perruisseau-Carrier et al 2010;Piazza et al 2010;Qin et al 2010b;Quin et al 2012;Hinsz and Braaten 2014) have a more dynamic reconfiguration capability. Other reconfigurable antennas resort to the use of varactors (Daviu et al 2007;Jeong et al 2008;Yang et al 2008;Jiang et al 2009;Oh et al 2010;Tawk et al 2012a;Bai et al 2013;Onodera et al 2013;Ramadan et al 2014) where varying the biasing voltage can result in varying the capacitance of the corresponding varactor.…”

While reconfigurable antennas have been implemented in various ways over the past 40 years, reconfigurable microstrip antennas, in particular, have existed for almost as long as the microstrip antenna itself, dating back to the early 1980s. The motivation for implementing reconfigurable properties in an antenna in general is straightforward -the acquisition of new capabilities that eliminate the need for multiple antennas and/or that provide additional degrees of operational freedom that expand system performance. Microstrip antennas are particularly good candidates for achieving reconfigurability, since their well-defined ground planes and planar structures present clear opportunities for integration of a number of popular reconfigurable mechanisms (including switches and tunable materials) and their associated control circuitry. Additionally, since most microstrip antennas operate in resonance and their operation is well modeled and well understood, an informed designer can manipulate the antenna structure and composition in different ways to achieve a variety of reconfigurable properties.This chapter addresses recent advances in the development of reconfigurable microstrip antennas, with an emphasis not only on the antennas themselves, but also on the practical issues surrounding their implementation, including control and system-level design and performance. Fundamentally, microstrip antenna behavior is governed by two kinds of properties: substrate properties and conductor properties. Section 6.2 describes the basic concepts behind changes in substrate parameters, including tunable changes in relative permittivity and permeability, as well as some recent examples that produce useful reconfigurability. Section 6.3 addresses changes in the conductive components of microstrip antennas that can lead to a wide variety of reconfigurability. Section 6.4 discusses many of the important issues surrounding the practical Microstrip and Printed Antennas: New Trends, Techniques and ApplicationsEdited by Debatosh Guha and Yahia M.M. Antar

“…In [15], a reconfigurable antenna combining both frequency and radiation pattern reconfigurabilities was introduced. In polarization-reconfigurable antenna, the polarization can be switched from linear to circular [16] and from left-handcircular polarization (LHCP) to right-hand-circular polarization (RHCP) [17]. A novel reconfigurable-patch antenna with both frequency and polarization diversities was studied in [18].…”

This paper presents an H-shaped reconfigurable antenna fed by a coplanar waveguide (CPW) for wireless applications. The antenna consists of an H-shape radiator and a CPW printed on a PCB and a varactor diode connecting the upper and lower arms of the H-shape radiator for reconfigurability. The uniqueness of the antenna lies on the ability to select the operating mode and frequencies electronically using a varactor diode. By selecting the DC bias voltages of 11.5, 10 and 8 V across the varactor diode, which in turn selecting the corresponding varactor capacitances of 2, 4 and 6 pF, the antenna can be controlled to operate in three different modes, namely, a single-band mode to cover the Global System for Mobile communications 1900 (GSM1900) system, a dual-band mode at 1.88 and 2.4 GHz to cover the GSM1900 and Bluetooth or Wireless Local Area Network (WLAN) systems, respectively, and a tri-band mode at 1.57, 1.88 and 2.4 GHz to cover the GSM1900, WLAN and Global Position System (GPS), respectively. Furthermore, by varying the varactor capacitance from 7 to 13 pF, the GPS and WLAN bands can be tuned by 11.44 % (1.57 -1.4 GHz) and 6.46 % (2.4 -2.25 GHz), respectively, yet keeping the 1.88-GHz band unchanged. Thus our proposed single antenna can be used to support different wireless standards. Detailed studies on the reflection coefficient, current density, antenna pattern and gain are carried out using simulations and measurements to investigate the behaviour of the antenna at each resonant frequency in each operating mode.
