Abstract-A new configuration of Yagi antenna is proposed, which can improve the forward/backward ratio (f/b) significantly while maintaining a high gain. This configuration involves the addition of one radiating element to the original Yagi array. This additional element may arrange on parallel (side-by-side) or collinear to a radiating dipole of the original Yagi antenna. It is shown here that the technique is most effective for collinear configuration (exhibits smaller mutual effects) and that there then exists an optimum length and position for the added element. The amplitude of the excitation of the additional element determines the angular location of the back lobe reduction. To demonstrate the major benefits, comparisons are made among the proposed and conventional Yagi configurations. Numerical and measured results of our design show more than 20 dB front to back ratio at 2.4 GHz. Moreover, the proposed array represents a simple and valuable alternative to the stack Yagi antennas as the obtainable radiation characteristics are satisfactory in terms of both forward and backward gain.

“…With the fast development of wireless communication systems, such as 2G, 3G, LTE, Wi‐Fi, WiMAX, and ZigBee, it is desirable to have following antenna features: unidirectional radiation pattern, wide bandwidth (BW), stable gain, stable radiation pattern, easy integration, low profile, and so on . The printed quasi‐Yagi antenna (PQYA) with dipole elements, which was first proposed by Qian et al, has been extensively studied to achieve aforementioned properties either by modifying feeding structures or by modifying the shape of the driven elements …”

In this study, a new configuration of a low profile, broadband printed quasi‐Yagi antenna with two directly fed monopoles has been proposed. The property of a printed monopole antenna with a simple microstrip feed‐line has been used to simplify feeding structure of the printed quasi‐Yagi antenna. A broad bandwidth is achieved by cascading another monopole element of different lengths in a series to obtain two nearby resonances. The proposed antenna consists of two driven monopoles on one side of the dielectric substrate, whereas, on the other side, a reflector and a director are realized as parasitic monopole elements, directly on the ground plane. The measured impedance bandwidth of 70.2% (1.46‐3.05 GHz) with stable gain ranging from 4.7 to 5.3 dBi in the entire bandwidth has been achieved. The antenna has the front‐to‐back ratio better than 10 dB and cross‐polarization level below −20 dB in the direction of maximum radiation over the entire bandwidth. The simulated performance of the antenna has been experimentally verified with good agreement.

“…Nowadays, with the rapid development of smart and multifunctional communication systems, antennas and antenna arrays with wide frequency coverage and reliable radiation properties are demanded [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Among various kinds of antennas, the slot loop antenna (SLA) has raised research interests in academic and industrial fields for its simple configuration and good radiation properties.…”

Abstract-In this paper, a wide slot loop antenna with an adjustable back-reflector is introduced. Five working statuses are defined by simply adjusting the distances between the radiator and the reflector. Measured results show the total available operating band with better than 10 dB return loss ranges from 0.84 GHz to 3.04 GHz (113.4%). The radiation properties of the array are tested in an anechoic chamber. Stable unidirectional radiations with more than 8.3 dB gains are observed in the working band. Apart from that, the straightforward two-portion arrangement of the design provides costeffective solution for mass production. All these features make the antenna an appropriate substitute for multiple narrowband antennas.
