“…The proposed antenna in this paper is implemented using PRGW technology which has low loss at mm-wave frequencies compared to the antennas fed by transmission line since the wave propagates inside the air gap instead of a dielectric. In this work, implementing two FSS layers resulted in a higher beam tilt angle and higher gain enhancement compared to the structure presented in [9] using five layers and in [21] using two layers. In addition, in [22], five vertical layer metamaterial slabs are used to deflect the beam, which make the antenna complex and bulky, while the presented prototype in this paper exhibits less complexity in terms of fabrication and measurements.…”

A new design of the double dielectric resonator antenna (DRA) fed by a printed ridge gap waveguide for beam‐switching applications based on frequency selective surfaces (FSSs) is presented here. The dual‐sided printed FSS element works in its reflection mode and comprises a slotted square C‐shaped patch on the top layer and a square strip on the back plane. Therefore, the beam switching can be implemented by loading the proposed FSS array over and in the middle of DRAs. Loading the antenna with two layers of 3 × 3 FSS unit cells results in ±77° beam switching and a 3.16 dBi gain enhancement at 28 GHz. Simulation and measurements confirm the operation of the proposed antenna, with good matching and gain observed.

“…The tilted angle is a key parameter for designing a tilted-beam antenna. Generally, tilting the beams of the antenna can be accomplished by many ways, such as active beam tilting based on active components [3], mechanically tilting [4], and the passive beamsteering technique [5][6][7][8][9][10][11][12][13]. The electronically tilting beam needs the agile elements, such as diodes, phase shifter, etc., which always suffer from gain drop since a large number of components cause a large loss.…”

In this paper, a titled-beam antenna based on spoof surface plasmon polaritons (SSPPs) transmission lines (TLs) is proposed. The parallel SSPPs-TL is a slow-wave TL, which is able to limit waves in the TL strictly. By periodically introducing a set of tapered stubs along the SSPPs-TL, the backward endfire beams are formed by the surface waves in the slow-wave radiation region. Then, through the placement of a big metal plate below the endfire antenna, the backward endfire beams are tilted, and the tilted angle of the beams are steered by the distance of the metal plate and antenna. Over the band of 5.7 GHz~7.0 GHz, the tilted antenna performs constant shapes of radiation patterns. The gain keeps stable at around 12 dBi and the 1-dB gain bandwidth is 20%. The measured results of the fabricated prototypes confirm the design theory and simulated results.

“…An electromagnetic bandgap structure provides a good directional radiation characteristic by suppressing surface wave propagation [16]. Frequency selective surface layers offer reflective phase coherence in broadband to achieve good antenna performance [17]. These techniques provide unidirectional radiation patterns although they experience the same problem, that is, the reflector structure is complex with extremely large size.…”

“…These techniques provide unidirectional radiation patterns although they experience the same problem, that is, the reflector structure is complex with extremely large size. Compared with [15]- [17], a simple resonance-based reflector structure is proposed to provide unidirectional radiation in broadband, but it cannot reduce the profile height [18], [19].…”

This paper presents a compact circularly polarized microstrip antenna for radio frequency identification (RFID) readers. The dimensions of the proposed antenna are reduced by etching a cross slot in the radiation patch and loading four grounded coupling patches on the four corners of the radiation patch. An inverted Z-shaped coupling feedline is used to realize circularly polarized operation. The measured −10 dB |S 11 | bandwidth, 3-dB axial ratio bandwidth and maximum gain are 872−1095 MHz, 888−933 MHz, and 5.52 dBi, respectively, at 922 MHz frequency. The overall dimension of the proposed antenna is 0.36 λ g × 0.36 λ g × 0.05 λ g (λ g is the guide wavelength at the center frequency of 915 MHz). The proposed antenna has small size with good overall performance and is suitable for compact RFID devices.
