“…In such a case, even after the optimisation process, it is difficult to obtain isolation better than 50 dB [13,14,24]. The achievement of higher isolation requires the use of multilayer PCBs in which radiators and FN are separated by means of ground planes [9,[25][26][27]. Another important aspect of the dual-polarised antennas that affects isolation is the operational frequency band.…”

The paper describes the process of designing a dual-polarised linear antenna array with enhanced port-to-port isolation, with the example of a four-element array with isolation better than 60 dB for the U-NII 5.15–5.925 GHz band. As a single antenna, dual-polarised electromagnetically coupled microstrip antennas were used with port-to-port isolation not exceeding 25 dB. A significant improvement in the isolation of the array was achieved thanks to the application of a dedicated feeding network. On the basis of theoretical analysis, a mathematical model describing port-to-port isolation was developed. Circuit and full-wave simulations were carried out to show the influence of electromagnetic couplings between antennas and/or the microstrip lines of the feeding network and the selection of phase shifters/power dividers on the isolation. The fabricated prototype is characterised by a gain of about 14 dBi, polarisation purity of at least −27 dB within the main lobe and close to expectations isolation better than 57 dB within the whole operational band.

A polarization matched 2×2 radiating array for electronically steered phased array antenna is presented. The antenna array is a multi-layer structure consisting of four square microstrip patch elements grown on each substrate to provide wide band operation at S-band. Dual polarizations of radiated wave from the antenna array have been achieved by feeding the array in series fed mode through horizontal and vertical ports. Designed 2 × 2 S-band dual polarized series fed antenna has been optimized on a finite element based ANSYS HFSS full wave solver. Controlling the amplitude of RF signal at input ports, the polarization can be matched to the target antenna polarization, hence antenna can work as polarization matched antenna. Gain of the developed antenna is 13 dBi, and the return loss is better than 10 dB over the frequency range of 2.3 to 2.5 GHz. This antenna can be used as radiating array for electronically steered phased array for S-band SOTM (SATCOM On The Move) application where the polarization of the antenna changes with movement of host platform.

“…As such, the development of dual linear polarization antennas has witnessed many studies and designs particularly, in space polarimetric weather radar applications. Therefore, the demand for such systems is growing exponentially (Mishra, 2013;Luo et al, 2013). More importantly, a dual linear polarization antenna suffers from the most significant drawbacks.…”

Abstract. Dual linear polarization microstrip antenna configurations are very suitable for high-performance satellites, wireless communication and radar applications. This paper presents a new method to improve the co-cross polarization discrimination (XPD) for dual linear polarized microstrip antennas at 10 GHz. For this, three various configurations of a dual linear polarization antenna utilizing metamaterial unit cells are shown. In the first layout, the microstrip patch antenna is loaded with two pairs of spiral ring resonators, in the second model, a split ring resonator is placed between two microstrip feed lines, and in the third design, a complementary split ring resonators are etched in the ground plane. This work has two primary goals: the first is related to the addition of metamaterial unit cells to the antenna structure which permits compensation for an asymmetric current distribution flow on the microstrip antenna and thus yields a symmetrical current distribution on it. This compensation leads to an important enhancement in the XPD in comparison to a conventional dual linear polarized microstrip patch antenna. The simulation reveals an improvement of 7.9, 8.8, and 4 dB in the E and H planes for the three designs, respectively, in the XPD as compared to the conventional dual linear polarized patch antenna. The second objective of this paper is to present the characteristics and performances of the designs of the spiral ring resonator (S-RR), split ring resonator (SRR), and complementary split ring resonator (CSRR) metamaterial unit cells. The simulations are evaluated using the commercial full-wave simulator, Ansoft High-Frequency Structure Simulator (HFSS).
