This paper introduces new wideband antenna-filter-antenna (AFA) uniform arrays that can be utilized as frequency selective surfaces (FSS) with low loss and sharp roll-off response, which are highly desirable characteristics for millimeter wave applications. The design adopts a simple 3-layer single polarization structure consisting of two patch antennas and a resonator. Both simulations and measurements are used to characterize the performances of the proposed design. Overall results show 18.5% 10-dB bandwidth. For the targeted band the insertion loss is less than 0.2 dB. Possible applications include quasi-optical amps, grid mixers and radomes for aircraft radar antennas.Key Words: Antenna-Filter-Antenna, Bandpass Filter Antenna, Frequency-Selective-Surfaces, Gaussian Optics Measurement System. -mail: hamza.kaouach@gmail.com, hkaouach@uqu.edu.sa) This is an Open-Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/ by-nc/3.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. ⓒ

“…The microstrip transmitarray is rapidly used in both terrestrial and satellite communication systems because of its advantages such as high gain, low mass and volume, inexpensive manufacture, and no insertion loss of a phased array's feed network at millimeter wave frequencies [1][2][3][4]. Due to the planar array of printed patch elements, the transmitarray avoids the fabrication complexity inherent in lens antenna.…”

“…Thus, the design process must involve both the transmission phase shift and magnitude of the element. In addition, the severe drawback of the microstrip transmitarray is its limited bandwidth performance, which is usually 7% or less, and intense efforts have been made in recent years to overcome this shortcoming [1,4,5,7] and [8]. In this paper, we present a novel transmitarray operating at 9.5 GHz which uses a double-petal loop as the unit cell element and offers a wider bandwidth than previously achieved ones.…”

Abstract-In this letter, a four-layer transmitarray operating at 9.5 GHz is designed using a doublepetal loop element as the unit cell. A configuration of the double-petal loop elements is used to increase transmission phase variation while maintaining a wide transmission magnitude bandwidth of the unit cell, and a full transmission phase range of 360 • is achieved for a transmission magnitude equals to or better than −2.4 dB. Furthermore, the oblique performance of the unit cell is also good. Then, a primefocus 676-element microstrip transmitarray with the proposed element is fabricated and measured. The highest measured gain is about 22.15 dBi at 9.8 GHz, resulting in a 31% aperture efficiency. The antenna bandwidth of 10.2% (from 9.3 to 10.3 GHz) for 1-dB gain is achieved in this design.
