“…on both sides of the dielectric substrate [33]. A CP array using inclined LP patches [27,28], orthogonally fed slot ring array antennas [29,30], and square patch array antenna [31,32] have been reported where feed networks are designed using series-parallel microstrip-to-slot branch circuits to take the benefits of the both-sided MIC technology. Moreover, this type of feed network provides easy impedance matching and is suitable to configure large-scale extensible arrays.…”

A new circularly polarized microstrip array antenna using the orthogonal feed technique is proposed in this paper. The antenna has a multi-layer structure and a new 3-way power divider employing the both-sided microwave integrated circuit technology is designed to configure the feed network of the array. Circular polarization (CP) is realized by creating a quadrature phase difference between orthogonal feed circuits of the patches. The multi-layer structure gives flexibility to adjust the patch spacing that helps to reduce the sidelobe level of the antenna. It is found that the multi-layer structure exhibits a gain of about 2 dB higher than that of a single layer structure by means of sidelobe reduction. The proposed structure also exhibits good CP performances that are verified by a good agreement of measured and simulated results. Simple and compact structure makes the antenna suitable for various wireless applications.

Design and parametric analysis of a planar array antenna for circular polarization muhammad asad rahman 1 , quazi delwar hossain 1 , md. azad hossain 2 , eisuke nishiyama 3 and ichihiko toyoda 3 A new circularly polarized planar array antenna using linearly polarized microstrip patches is designed and optimized for X-band wireless communication applications. Four square patch elements with feed network are used to design the circularly polarized array antenna. The feed network consists of microstrip lines on the obverse side of the dielectric substrate and slot line on the reverse side of the substrate. Both-sided MIC technology is successfully employed to apply its inherent advantages in the design process of the array structure. The unequal feed line is used to create 908 phase difference between the linearly polarized patches. Therefore, the circular polarization is realized by the combination of linearly polarized patches and unequal feed line. Characteristics of the proposed array are investigated by using two electromagnetic (EM) simulators: advanced design system and EMPro. The 210 dB impedance bandwidth of the antenna is around 5%. The 3 dB axial ratio bandwidth of 1.48% is obtained. The design of the proposed antenna along with parametric study is presented and discussed.

“…An arrowhead-shaped slot integrated microstrip antenna has been discussed in [5] and arrowhead-shaped slot is embedded in the first quadrant along the diagonal axis of the square patch to achieve CP with antenna size reduction. CP has been achieved in [6,7] by employing the orthogonal feed technique. In [8], a technique for an array has been described to generate CP using linearly polarized patches creating unique angular and phase arrangements.…”

A 2 × 2 circularly polarized array antenna for X-band applications is proposed in this letter. A new technique is employed to attain circular polarization by means of linear polarization patches. Two orthogonal modes with quadrature phase shift is achieved by making two patches quarter wavelength ahead and orthogonal with respect to other two patches. The feed network of the array is designed using both-sided MIC technology to overcome the impedance matching problem of conventional feed networks. A 3-dB axial ratio bandwidth of 1.41% is obtained and antenna gain is around 6.36 dBic.
