“…It can be found that the proposed antenna shows competitiveness in terms of the number of reconfigurable CP bands and diodes. The antenna in [11] has the smallest size but uses four diodes. Meanwhile, the antenna in [12] uses two diodes but the number of reconfigurable CP bands was limited to two.…”

“…In addition, the features of a bi-directional radiation pattern and a low profile are required for some applications, in which monopole or slot structures were commonly utilized [8,9,10]. Multi-band reconfigurable CP antennas using the monopole structure were published in [11,12]. By controlling the state of four PIN diodes placed between the feedline and four radiating arms, the sense of polarization was interchanged at two CP bands [11].…”

In this paper, a simple design for a triple-band circularly polarized (CP) antenna with the capability of switching its polarization between dual-sense CPs is presented. The proposed antenna is comprised of a monopole loop antenna as a primary radiator. By placing a parasitic loop around the primary radiator, an additional CP band is achieved. Reconfigurability of the polarization between right-hand CP (RHCP) and left-hand CP (LHCP) at three different frequencies of 2.5, 3.3, and 3.8 GHz was realized by controlling the ON/OFF states of two PIN diodes. For validation, the fabricated antenna yielded an impedance bandwidth of 52.6% (2.34–4.01 GHz), while the axial ratio bandwidths for both the RHCP and LHCP states were 3.5% (2.47–2.56 GHz), 6.6% (3.20–3.42 GHz), and 2.4% (3.74–3.83 GHz). The measured broadside gains within the axial ratio bandwidth were 1.2, 2.7, and 1.4 dBi, respectively. Compared to other reconfigurable multi-band CP antennas, the proposed design is the first work to achieve a reconfigurable polarization at three distinct bands at a low fabrication cost by using only two diodes. The proposed antenna is suitable for WLAN and WiMAX applications.

“…In [13], the antenna could realize different CP radiation characteristics by injecting water into different holder. In [14], several p-i-n diodes were used to control the polarization switching of the antenna. The same method was employed in [15], in which an L-probe fed square patch antenna with reconfigurable feeding network was reported.…”

A wideband and dual circular polarization hollow patch antenna fed by a tapered fold coupled structure is presented for distance detection application. The proposed antenna consists of a gear-shaped ring radiation patch etched on a three-layer dielectric substrate, four tapered folded feedlines, a ring ground plane and a feeding network. To achieve right-handed circular polarization (RHCP) and left-handed circular polarization (LHCP) characteristics, four hybrids are employed. The proposed hollow antenna can be seamlessly integrated and installed under the cover of sharp shaped aerobat without effect on its flight characteristics. As a proof-of-concept, an antenna working at 1.8 GHz is prototyped and tested. The measured and simulated results show that the proposed antenna exhibits a wide impedance bandwidth of 270 MHz (1.695-1.965 GHz) and a wide 3-dB axial ratio (AR) beamwidth of 140 degree.

“…The first one is to use a reconfigurable feeding network to feed different parts of the antenna . The second one is directly introducing controllable perturbation segments on the antenna's radiating part , . For examples, in literatures, polarization‐reconfigurable E‐shaped patch antennas were proposed, which are capable of radiating either right‐hand circular polarization (RCP) or left‐hand circular polarization (LCP) waves by directly introducing perturbation in an E‐shaped patch.…”

This article reports a novel polarization-reconfigurable antenna array using the technique of mode combination (MC). It can electronically alter its polarization states between left-hand circular polarization mode, right-hand circular polarization mode, and linear polarization (LP) mode. The antenna array consists of 2 × 2 microstrip antenna elements with one L-slot on each square patch and two PIN diodes located in the slot region. Instead of degenerating circular polarization (CP) and LP modes by exciting different radiation parts of the antenna element, the LP one is combined by orthogonal CP modes generated by adjacent elements of the proposed antenna array. To verify the concept, a prototype is manufactured and tested. Experimental results show that the proposed antenna has an overlapped −10 dB impedance bandwidth of around 11.2% for both CP modes and the LP one. The realized maximum gains are around 7.5 dB for the CP modes and 5.6 dB for the LP mode, which are satisfactory for wireless local area network in wireless communication systems.
