This paper presents a detailed study on a family of circularly polarized (CP) antennas inspired by the dual-mode substrate integrated waveguide (SIW) cavities. The related design methodology has been proposed and summarized for the first time. The field distribution for dual-mode SIW cavities (using TE 102 , TE 201 and TE 103 modes) are first analyzed. Based on the current flow of the orthogonal modes, slot cuts are incorporated on the top surface considering both the phase and current magnitude, which leads to optimal boresight CP radiation. All the feasible slot combining configurations which are able to generate CP radiation for the dual-mode cavities are summarized and characterized. For experimental verification, four lowprofile, low-cost and high-efficiency CP antennas using the dual-mode cavities are proposed, analyzed and implemented, including two CP antennas based on the degenerate TE 102 /TE 201 half-mode-like resonators, and a CP antenna as well as its 2-element array using the degenerate TE 103 / TE 201 dual-mode cavity. The measured and simulated results are in excellent agreement. Useful design guidelines are provided. These antennas show a measured bandwidth varying from 2.0 % to 4.1 % and a peak gain ranging from 7.0 dBic to 9.4 dBic, respectively. They demonstrate good CP performance and high radiation efficiency which is better than 88 % in simulation. They offer attractive features including interesting working principle, easy implementation, low-cost, and non-sensitivity to tolerance, appearing as good candidates for high-frequency directive antenna application.

“…There are many slotted antennas in the literature utilizing planar SIW, where both of longitudinal slot [8] and transverse slot [9] on the broad wall of an SIW can be used as radiating elements for a linearly polarized SIW slot array. A nonlinearly polarized SIW slot antenna array can be designed by rotating the slots [10][11][12][13] or cavities with compound slots [14][15][16][17][18], or even using annular, triangular or split ring slots [19][20][21]. However, sometimes sizes of these antennas may be too large for practical applications and highly affect the integration process.…”

In this paper, a novel HMSIW slot antenna combines a significant bandwidth enhancement and small footprint for inter-satellite communications at C-band. The designed antenna has the capability of achieving a reduction of size with nearly 50% in comparison to conventional SIWs. The results show that the proposed antenna has a bandwidth of 4%, an average gain of 5.8 dB, and the radiation efficiency of η = 93% at 5 GHz.

A ultra-light, compact, high gain 16 × 6 CP antenna array for Ku band mobile satellite applications is presented in this paper. The 96-element array consists of 24 2 × 2 CP sub arrays fed by a substrate-integrated-waveguide (SIW) network. Two essential and innovative techniques were adopted in this design. First, in order to achieve the ultra-light weight, the radiation patches were etched on the Polyimide film supported by a patterned foam. A piece of thin SIW network was designed to feed the radiators. The total weight of the fabricated array prototype is only 66.5 gram and profile is low as 0.05 λ0. Second, a sequential rotation (SQR) feeding technique was applied to the aperture fed 2 × 2 CP sub array, which realized more than three times bandwidth enhancement than the direct (non-SQR) feeding approach. In addition, the measured results show the CPoperational bandwidth is 700 MHz from 11.55 to 12.25 GHz. The peak realized gain is 26.4 dBic and gain variation is stable (less than 3 dB) cross the entire operating bandwidth. With ultra-light and high gain, it is an excellent candidate for Ku band satellite applications.
