“…By cutting off the metallic area of the antenna where the current amplitude is small when it radiates, the antenna can achieve a low RCS while maintaining a good radiation performance [10][11][12]. The HIS takes advantage of its zero reflect phase to cancel out the reflection waves from the perfect electric conductor (PEC) of the antenna [13,14]. However, the gain of the antenna will decrease.…”

Abstract-A new method for reducing the in-band radar cross-section (RCS) of a patch antenna within its operating frequency is presented. This method is based on the utilization of band-pass frequency selective surface (FSS) consisting of non-resonant constituting elements. The main novelty of this method is that it allows for the use of an FSS structure to reducing the in-band RCS of antennas. To validate the proposed method, a low RCS patch antenna resonating at 5 GHz is designed using this method. The simulated results show that the largest RCS reduction is about 15 dB at 5 GHz. A prototype of the proposed antenna is fabricated and tested in an anechoic chamber, and good agreements between the measured and simulated results are demonstrated.

“…The surface wave restricts the wide use of microstrip antenna, electromagnetic bandgap (EBG) or photonic bandgap (PBG) structure is a method to reduce the surface waves, which exhibit band-gap feature [6] too. EBG has been applied in the field of antenna to improve the performance of antenna [7][8][9][10][11][12], such as suppression of surface wave propagation, increasing the gain of antenna and improving the radiation pattern by inserting the EBG structure into the substrate [13][14][15]. However, in implementing EBG, a large area is needed to implement the periodic patterns and it is also difficult to define the unit element of EBG.…”

“…Frequency selective surface (FSS) is periodic spatial filtering structure, which has been widely used for many applications such as radome, filter, dichroic subreflector, directivity enhancement, and radar cross section (RCS) reduction [1][2][3][4]. Recently, some engineers use FSS in wireless security and mobile communications [5][6][7][8].…”

A compact bandstop frequency selective surface (FSS) using fractal structure is proposed. This flexuous design elongates the cell perimeter of the ring-shaped FSS, which means the cell size gets smaller at the same resonance frequency. Furthermore, the unit cells adopt regular hexagon and the array employs equilateral triangle form. Because of its symmetric configuration, good frequency stability has been achieved for both horizontal and vertical polarizations at different oblique angles. For the stable bandstop character, this FSS can be used for protecting the staff of S-band radars against electromagnetic radiation, while the 900/1800/1900 MHz mobile bands and the 5.2/5.8 GHz wireless local area network signals are not affected.

Dmitriev, Theoretical analysis of a modified Koch monopole with reduced dimensions, IEE Proc-Microw Antennas Propag 5 (2006), 475-479. ABSTRACT: A 15-by-20-mm 2 dual-broadband printed monopole antenna fed by a coplanar waveguide is presented. With a numeral-7 slit etched from the rectangular radiating element, the antenna can excite for its lower and upper impedance bands two and one resonant modes, respectively. With a back-patch appropriately printed on the other side of the substrate, a lower (upper) impedance band with a bandwidth of 39.3% (19.5%) can be obtained. These two impedance bands can cover the frequency bands required by UMTS/IMT-2000/IEEE802.11a/b/g/ WiMAX.
