“…Frequency tunability in Vivaldi antenna was studied in [11]. High impedance surfaces [12], loops with diodes [13], multiple lumped switches [14] and multiple diodes in irregular manner [15], are used for reshaping the beam direction. A dual-polarized antenna with different frequency choices using metamaterial was presented in [16].…”

A printed and minimal size antenna having the functionality of frequency shifting as well as pattern reconfigurability is presented in this work. The antenna proposed in this work consists of three switches. Switch 1 is a lumped switch that controls the operating bands of the antenna. Switch 2 and Switch 3 controls the beam switching of the antenna. When the Switch 1 is ON, the proposed antenna operates at 3.1 GHz and 6.8 GHz, covering the 2.5-4.2 GHz and 6.2-7.4 GHz bands, respectively. When Switch 1 is OFF, the antenna operates only at 3.1 GHz covering the 2.5-4.2 GHz band. The desired beam from the antenna can be obtained by adjusting the ON and OFF states of Switches 2 and 3. Unique beams can be obtained by different combination of ON and OFF states of the Switches 2 and 3. A gain greater than 3.7 dBi is obtained for all four cases.

A right-hand circularly polarized beam steering spiral antenna is presented in this article. It is designed using the standard pi-n technology, enhanced with arm switches and biasing lines. The ensuing design is easily manufactured and is functionally competitive with the more complex ones, based on RF-MEMS. Three beams, tilted 40 with respect to the spiral central axis, are generated at 3.3 GHz, suitable for WiMax systems at this frequency. These beams are directed at approximately 90 , 180 , and 270 in the azimuth space. Beam directions depend on various configurations of the seven p-i-n diodes added to the spiral structure. The states of the diodes are subjected to the two DC bias voltages connected to the spiral arm. The radiation performance over the 200-MHz bandwidth (3.2-3.4 GHz) is relatively stable. Measurements in this band show the reflection coefficient below 210 dB and the axial ratio below or close to 3 dB at the peak beam directions.

“…With the rapid development of wireless communication, pattern reconfigurable antennas have drawn lots of attention because they enable to provide dynamic radiation coverage, mitigate multipath fading, and improve beam steering capability of phased array systems. In the past decades, there exists an extensive literature on the design of pattern reconfigurable antennas . Different methods are used to reconfigure the radiation pattern: one way is selection of different radiating structure including shorting sections , parasitic elements , and antenna shape , or adjustment of radiating elements , another is switching between different feed networks .…”

The design of a planar reconfigurable antenna with bidirectional end‐fire and broadside radiation patterns from a common aperture is presented in this article. The proposed antenna is composed of two series‐feed collinear slot subarrays corporately fed by a microstrip line and two series‐feed dipole subarrays corporately fed by a microstrip line‐to‐double side parallel strip line transition, respectively. A prototype for 2.4 GHz wireless local area networks applications is fabricated and measured. The measured realized gains are about 11—12 and 7–8 dBi for broadside and end‐fire patterns. Experimental results, which agree with the simulated ones, verify that the proposed antenna is a good candidate for pattern reconfigurable applications. © 2014 Wiley Periodicals, Inc.
