“…As we know, the tilted beam patterns could be successfully obtained by using the microstrip Yagi antenna, and this design concept was first proposed by Huang in 1989. After that, a variety of works contributed to the improved performances of the Yagi antennas . For example, in References , the directivity of the antenna was enhanced by adding additional parasitic patches.…”

A dual‐band dual‐mode microstrip Yagi antenna with quasi‐end‐fire radiation patterns is proposed in this paper. It consists of five radiating patches driven by a single slot‐loaded patch placed in the middle. Meanwhile, two slot‐loaded parasitic patches are symmetrically located on two sides of the driven patch, respectively. In the lower band, the five patches involved resonate at TM01 mode. While in the upper band, all the patches resonate at TM02 mode. In order to ensure quasi‐end‐fire radiations in the both bands, four slots are symmetrically etched around the strongest surface currents of each patch resonating at TM02 mode. As a result, the resonant frequency of TM02 mode is decreased dramatically, while the resonant frequency of TM01 mode almost remains unchanged. With these arrangements, the separations between any two of the adjacent patches at their centers satisfy the requirements in design of the microstrip Yagi antenna in both bands, so as to realize the dual‐band dual‐mode microstrip Yagi antenna on a single‐layer substrate. Finally, an antenna prototype is fabricated and tested. The measured results reveal that the dual operating bands of 2.76~2.88 and 4.88~5.03 GHz for |S11| < −10 dB are satisfactorily achieved. Most importantly, the proposed antenna can indeed realize the quasi‐end‐fire radiation patterns in dual operating bands.

“…Reconfigurable radiation pattern was realized in References , by controlling the states of the pin diodes. As reported in Reference , the improved gain was realized by utilizing a PBG structure. Additionally, in References , the beam tilted angle was enlarged by utilizing some other modes rather than fundamental mode of the patch antenna.…”

“…The large size of this antenna was also the source of other difficulties [12]. Later, many methods were proposed to improve the gain and F/B ratio of these antennas, such as using a periodic band-gap (PBG) structure [13]. These periodic structures affect the transmission of propagating waves.…”

Abstract-This paper presents a design of Wide-Band Microstrip Yagi-Uda antenna with high gain and high front to back (F/B) ratio. Numerical and measured results of our design show more than 18 dB front to back ratio at 5.5 GHz and no backward radiation at 5.2 GHz. An impedance bandwidth of 22.05% was achieved around 5.5 GHz. The antenna gain (10-12.4 dBi) can be varied to be suitable for various applications. Measured return loss and radiation pattern of this antenna is presented to validate the results of simulations by two methods. The first method based on finite element method (FEM) and the second one based on finite integral technique (FIT) were used to analyze antenna structure, and subsequently the Genetic Algorithm (GA) was applied by using HFSS simulator to obtain the optimized parameters. In order to find the best design method for this antenna, the effect of distance between the parasitic elements of proposed antenna was studied. Finally two microstrip Yagi-Uda array antennas were combined to increase the gain of antenna. To demonstrate the major benefits, a comparison of our initial and final designs of Yagi-Uda antenna is provided.

“…Since Huang's initial design, there have been some modifications to this antenna design process and configuration to address these limitations. Padhi and Bialkowski developed a periodic bandgap (PBG) structure that can be applied to microstrip Yagi antenna arrays for reducing the crosspolarized radiation and increasing the gain [2]. DeJean and Tentzeris developed a printed microstrip Yagi antenna array that can achieve a gain above 10 dB and a high F/B ratio (as much as 15 dB) that can be used for ISM, HIPERLAN, and millimeter-wave applications above 30 GHz [3].…”

“…Throughout the last several years, many contributions have taken place in the design and optimization of printed microstrip Yagi antenna arrays [1][2][3][4]. John Huang introduced the first standard design in 1989 for mobile satellite (MSAT) applications, which required a low-cost, low-profile antenna that covers a 40º beamwidth [1].…”
