“…Circularly polarized mode can be realized by various antenna types, such as slot antenna [1][2][3][4][5][6][7][8], coplanar waveguide model [9], and dielectric resonator antenna [10]. Among these antennas, slot antenna has attracted much attention due to the advantagious features of simple structure, wide band, and easy integration.…”

Abstract-This communication presents a novel compact and wideband circularly polarized (CP) slot antenna fed by microstrip feedline. The proposed antenna consists of a corner-truncated square-ring slot patch and a novel bent strip. The CP radiation is formed by using the bent strip to excite CP resonance modes. By intruding several open stubs to the corners of the square-ring slot patch, the impedance matching and axial ratio (AR) bandwidth are improved. The measured results show that the proposed antenna has the advantage of wideband characteristics in terms of an impedance bandwidth of 90.59% (3.2-8.5 GHz) and 3-dB axial ratio bandwidth of 84.2% (3.3-8.1 GHz). The principle as well as simulated and measured results of the proposed antenna is revealed.

“…For this quest, there are various strategies using layered structures to generate the bidirectional CP wave with identical or opposite helicities. For example, slot apertures are a well-known method to produce bidirectional CP wave, but with intrinsically opposite helicities 11,12 . To achieve the identical helicities, structures with multiple layers (more than two layers) are indispensable, for example, a three-layered frequency selective surfaces or back-to-back patches with a common ground (three metallic layers and two dielectric layers) 13,14 .…”

Efficiently manipulating the polarization states of electromagnetic waves is of great importance for communication, imaging, and sensing. In this paper, we aim to control the circular polarization states, e.g., left-hand, or right-hand, for the bidirectional radiated waves utilizing a pair of back-to-back quarter-wave plates, which are integrated within an ultrathin cavity. As an example, a bidirectional circularly polarized wave with the same helicity in forward and backward is generated based on numerical analyses, and proved by experiments in microwave region. The proposed ultrathin back-to-back quarter-wave plates cavity can be adopted to higher frequencies, e.g., terahertz and mid-infrared ranges, with lower metallic conductivity. The proposed method exhibits the advantages of compact dimension and low-cost implementation in engineering the bidirectional polarization states of electromagnetic waves.

“…Air is used as the substrate, while dimensions are shorted using a shorting wall and coaxial probe. Circularly polarized (CP) wide slot antenna feed by a microstrip with wide axial ratio bandwidth for C band applications has been reported in [7]. The overall design is very simple and unique to achieve 3 ㏈ axial ratio band by protruding a horizontal stub from the ground plane to wards the centre of wide slot (WS) and then feeding the WS with a microstrip feed line positioned to the side of the WS, underneath the protruded stub.…”
