A CPW fed elliptical patch antenna with reconfigurable polarization states among elliptical polarization (EP) and circular polarization (CP) is proposed. The proposed antenna has an elliptical patch on which cuts have been made symmetrical to minor axis of ellipse to obtain elliptical polarization. Circular polarization (CP) and Elliptical polarization are generated due to the discontinuity introduced by the cuts. In the proposed antenna, CPW feeding is used to increase the percentage bandwidth.

“…A frequency agile antenna is proposed for software defined radio application in [8] where in frequency reconfigurability is achieved by activating four groups of PIN diodes that connects central patch to four different peripheral patches that provides 2 4 = 16 reconfiguring states. A symmetrical multipolarized circular patch antenna that generates six LPs at 30° interval using 12 p–i–n diodes placed across a circular ring slot on the patch is proposed in [9], an aperture-fed polarization reconfigurable antenna that switches between horizontal, vertical, and 45° linear polarizations in dual bands is proposed in [10]. A very high-gain beam switching antenna that can steer beam in five directions in both azimuth and elevation planes using four parasitic patches for WiMAX applications is proposed in [11].…”

This paper presents different reconfigurable antennas with frequency, polarization, and pattern diversities. All the antennas have a very simple, novel, and compact structures, which are used for different wireless communication applications. These antennas employ switching for obtaining different reconfigurations. At first, an E-shaped antenna is designed for multi-band frequency reconfigurability. Second, circular and rectangular-shaped patch antennas are designed for achieving diversity in polarization. At last, a pattern reconfigurable antenna is designed with multiport excitation. These antenna performances are analyzed using various parameters such as return loss, radiation pattern, voltage standing wave ratio (VSWR), and gain. The prototypes of the antennas are fabricated and measured results along with simulated ones are presented. Both the results are in good agreement.

“…Most of them were capable to switch between several modes (ultra-wideband (UWB), narrowband (NB) mode, multi-bands mode etc.). To allow the operating frequencies and the bandwidths to be reconfigurable, switching components are used; PIN diodes [4,5], varactor diodes [6] or microelectromechanical system switches [7] are the most frequently used components in the design and fabrication of reconfigurable antennas.…”

Switchable UWB/narrowband/bi‐bands octagonal antenna using PIN diodes

A reconfigurable octagonal antenna with a capability to operate in ultra-wideband (UWB), narrowband (NB) or bi-bands is presented. By incorporating two resonators, computation between the proposed modes becomes possible using the PIN diode switches. The UWB mode is obtained by deactivated the two resonators, while the one NB mode, is gotten by activated just one resonator. In the case of the activation of the two resonators at the same time, the antenna will be operating in the bi-bands mode. The prototype has been simulated and measured. Both simulation and measurement have shown the same results and characterize a reconfigurable behavior, necessary for wireless applications.
