“…SIW-based cavity-backed antennas using higher-order modes for LP operation have been studied in literatures [13], [14]. In [13], an additional substrate layer for the feeding waveguide is required to excite the main cavity which increases the structure complexity as compared to the proposed antenna in this letter.…”

“…Whereas, the cavity in [14] is excited by a diagonal grounded coplanar waveguide (GCPW) which generates parasitic radiation. Moreover, both cavities in [13], [14] necessitate the using of dividing vias or tuning vias located at the edges of each subsection inside the cavities which are not necessary in our design.…”

In this letter, a single-fed low-profile high-gain circularly polarized slotted cavity antenna using a high-order cavity mode, i.e. TE 440 mode, is proposed. The proposed antenna has a simple structure which consists of a radiating linearly polarized slotted cavity antenna and a linear-to-circular polarization converter. An antenna prototype operating at WLAN 5.8 GHz band fabricated with low-cost standard printed circuit board (PCB) process is exemplified to validate the proposed concept. Measured results compared to their simulated counterparts are presented, and a good agreement between simulation and measurement is obtained.

“…[4] describes Ultra-wideband spatial and polarization diversity for twoelement arrays on a rigid substrate. Furthermore, [5] presents a four-element dual-spatial, dual-polarization broadband slotcoupled patch array on an FR-4 substrate, with only 15 dB isolation between the antenna elements, while [6] and [7] describe Substrate-Integrated Waveguide (SIW) cavity-backed arrays with a single feed line, hence, without applying diversity. In [8], 20.8 mm high metamaterial mushrooms walls increase isolation between neighbouring elements in a MIMO antenna system.…”

Abstract-The emergence of miniaturized flexible electronics enables on-duty first responders to collect biometrical and environmental data through multiple on-body sensors, integrated into their clothing. However, gathering these life-saving data would be useless if they cannot set up reliable, preferable high data rate, wireless communication links between the sensors and a remote base station. Therefore, we have developed a fourelement ultra-wideband textile cross array, that combines dualspatial and dual-polarization diversity, and is easily deployable in a first responder's garment. The impedance bandwidth of the array equals 1.43 GHz, while mutual coupling between its elements remains below -25 dB. For a maximal bit error rate of 1e-4, the array realizes a diversity gain of 24.81dB. When applying Adaptive Subcarrier modulation, the mean throughput per OFDM subcarrier increases by an extra bit/symbol when comparing fourth to second order diversity.

“…Slots inclined to 45 o with respect to array axis, placed along the waveguide to reduce the side lobe levels, are presented in [6]. Cavity backed slot antennas are presented in [7], [8] but these references use higher-order modes to excite the cavity. These higher-order modes result in large sized cavities leading to distance between the radiators to be greater than g , which causes unwanted grating lobes when combined into an array.…”

Substrate integrated waveguide (SIW) antenna array design with orthogonal polarizations with respect to the array axis is proposed. The antenna structure consists of three layers containing a feeding network, cavities and dielectric cover. The proposed design can achieve any desired polarization and it can be used to design two dimensional arrays. Two 10 element arrays are fabricated with polarization parallel and orthogonal to the array axis. These arrays provide 1GHz impedance bandwidth in automotive radar frequency range (76-81GHz). The designed beamwidth is 9 o in the plane parallel to the array axis and 120 o in the perpendicular plane. Approximately 20dB cross polarization rejection is measured in the desired field of view. The matched measured and simulated results show the validity of the proposed design.
