A novel W‐band arbitrary polarization compact radiating structure that can be used to design antenna arrays with wide angle beamforming and limited grating lobes is described in this article. The radiating element is a slot which can be oriented in any direction to achieve the desired polarization. This slot is placed on a rectangular cavity, which is operated in its fundamental mode to achieve compact size. The cavity is coupled with a substrate‐integrated waveguide feed line using a coupling slot. These radiating elements are series fed to form compact one‐dimensional arrays, which can be combined to design two‐dimensional arrays having field of view up to 120° and with limited grating lobes in the plane transverse to the one‐dimensional array axis. One‐ and two‐dimensional arrays for two orthogonal polarizations were fabricated and tested to validate the described structure.

“…Another factor is some reflections near the antenna mounting on the mast, especially when measuring the radiation pattern in the E plane. For completeness of our work, a comparison between the proposed antenna and some recent dualband compact size antennas [30][31][32][33][34][35][36] is summarized in Table 1. It is worth to mention that the antenna size comparison is based on the radiator size.…”

This paper presents a zeroth order metamaterial substrate integrated waveguide antenna. The antenna is designed to have a compact size based on employing only one composite right/lefthanded cell. The antenna resonates at 6.1 GHz with overall radiator size of 14.4 mm × 8 mm which represents 50% size reduction compared to conventional microstrip patch antenna that operates at the same frequency. The zeroth order mode of the antenna has been verified using analytical explanation and full wave simulations. Moreover, the full wave simulations and experimental measurements have been employed to confirm the antenna matching properties and radiation characteristics.

“…In recent years, an emerging and favorable candidate for implementation of waveguide‐based circuits in planar form is SIW 8,9 . Several dual‐band antennas have been developed with SIW technology because of its low‐cost fabrication, light weight, and compact size 10‐13 . In Reference 10, SIW rectangular or circular cavity have been used to implement cavity‐backed antennas to widen the bandwidth and enhances the antenna gain.…”

In this article, a novel design of compact cavity-backed slot antenna based on substrate integrated waveguide (SIW) technology is presented for dual-frequency communication services. A single layer printed circuit board is applied to implement the proposed antenna. The bowtie-ring slot engraved on the SIW square cavity is excited using two orthogonal microstrip feed lines to operate at two distinct frequencies (6.62 GHz and 11.18 GHz). The proposed antenna allows each of these frequencies to be designed independently. A prototype of the proposed cavity-backed antenna that radiates at both 6.62 GHz and 11.18 GHz is fabricated and measured. The port isolation better than 29.3 dB is achieved by utilizing the transmission zeros (TZs), which are produced due to the orthogonal feed lines, TE 110 mode and coupling between the TE 120 and TE 210 modes. The measured peak gains of the proposed diplexing antenna are 5.77 dBi and 5.81 dBi at lower and upper resonating frequencies, respectively. The proposed dualfrequency antenna exhibits the front-to-back-ratio (FTBR) and cross-polarization level greater than 26 dB and 21 dB, respectively, at both resonating frequencies.
