“…With the development of wireless communication technology, the demands for highly directive antennas are becoming more and more stringent [1] . Traditional technologies for obtaining high gain antennas are mainly based on reflectors [2] , dielectric lenses [3] , waveguide horns [4] and microstrip antenna arrays [5] , which may suffer from design complexity, high cost and power losses in the feeding network [6] . In recent decades, electromagnetic band gap (EBG) structures have attracted a lot of interest from the electromagnetic community for applications in controlling electromagnetic waves [7] .…”

In this paper, a novel partially reflction surface (PRS) is proposed. It is a single layer periodic array, which is composed of two folded long dipoles, two rectangular patches and four short dipoles. Two folded long dipoles are main resonant cells, which provides positive reflection coefficient phase gradient. In addition, two rectangular patches and four short dipoles can improve reflection coefficient magnitude to some extent. Compared with other papers, the novelty of this paper is that the proposed structure is single array, but the most proposed structure of other papers are dual layer periodic patch arrays. The reflection coefficient phase of this PRS increases linearly with operating frequency from 6.1GHz to 6.7GHz. The simulated results show that the reflection coefficient phase of this PRS is completely consistent with the theoretical reflection coefficient phase, the reflection coefficient magnitude of this PRS ias about 0.728 at 6.48GHz. Therefore, it can be used as superstrate of the Fabry-Perot resonator antenna for enhancing its half-power fractional bandwidth and gain.

“…The formula (2) indicates that a wideband FP resonator antenna could be obtained by using a PRS with a positive reflection phase gradient over operating frequency. In fact, the PRSs with a positive reflection coefficient phase gradient have been designed in [12] and 13].…”

“…The structure of the antenna is the major factor to dominate the radiation patterns. The studied slot patch antenna was originally designed with the maximum radiation patterns along the +Z axis [30][31][32], however, the rectangular slot line reversely creates the maximum radiation pattern occurring along the −Z axis [33,34]. Generally, it is defined the radiation E plane is the Y Z plan.…”

Abstract-In this paper, without using external power and active components, a design of pin coupled functional antenna tuner is presented. The tuner consists of two parts, a coupling pin and a tuning circuit. It is used to tune the bandwidth and antenna gain of the proposed slot patch antenna. The prototype, including a slot patch antenna and the tuner, was constructed and excited through a T-shape microstrip feed circuit resonated at 2.6 GHz. The impedance bandwidth BW (−10 dB return loss) of the slot patch antenna without coupling to the tuner was 3% referred to the operation frequency at 2.6 GHz. When the tuner was matched with the impedance 75 Ω through the coupling pin to the proposed antenna, the BW of the antenna was increased to 11% operated at 2.6 GHz. However, if the tuner was matched with the impedance 25 Ω to the proposed slot patch antenna, the impedance bandwidth of the antenna was increased 21% at operation frequency. Relatively uniform antenna gain was obtained when the matching impedance was decreased from 75 Ω to 20 Ω. In the meantime, the lower matching impedance corresponds to more reducing cross-polarization of the proposed slot patch antenna can be observed in the measured field patterns.
