“…DMS are used to enhance the behavior of different planar passive circuit and perform a serious LC resonance property in certain frequency and suppress the spurious signals [7]. Accordingly, DMS increases the electric length of microstrip line and disturbs it current distribution, and the effective capacitance and inductance of a microstrip line increase [8].…”

Abstract-Use of discontinuities in microstrip lines is currently employed to improve the performance of different passive circuits, including size reduction of amplifiers, enhancement of filter characteristics and applications to suppress harmonics in patch antennas. This paper presents an improved method of size reduction of a microstrip antenna using Defected Microstrip Structure (DMS) that it is used to perform serious LC resonance property in certain frequency. The DMS is integrated in antenna structure, and therefore this method keeps the antenna size unchanged and makes a resonance frequency. This resonance is due to the abrupt change of current path of antenna that resonates at 5.8 GHz which is shifted to 2.69 GHz thanks to spiral DMS. A prototype of the antenna was fabricated with an FR4 substrate and tested.

“…The size reduction of 45% is achieved using fractal gasket carpet Antenna and than by placing spiral arms in the same further reduces the size to 50% and multiresonant frequencies is obtained in [9]. The suppression of harmonics and size reduction of 43% is achieved by using DGS [10] further size reduction of 50% and 90% of microstrip antenna is presented in [12,13] using DGS and slots. The multiband operation in microstrip antenna is shown in [14] and [15] by etching Pentagonal and skew F shaped on Ground plane.…”

A novel dual layer rectangular printed Antenna based on loop type Frequency selective surfaces with five concentric rings and I shaped defected ground structure (DGS) is designed and investigated. The designed antenna is for applications in C band, WiFi devices and some cordless telephones and X band radiolocation, airborne and naval radars as multiband operational frequencies are at 5.5GHz, 6.81GHz, 9.3GHz and thus covers two wireless communication band C Band (4 to 8 GHz) and X band (8 to 12 GHz) The bandwidth is 200 MHz, 300 MHz and 1 GHz respectively and measured gain of this designed antenna are 2.42dBi against 5.5GHz, 2.80dBi against 6.81GHz, 6.76dBi against 9.3GHz. The proposed antenna in addition to multiband operation also exhibits miniaturization. The Floquet port technique is used to analyze concentric rings. The results comparison of proposed structure with the basic dual layer antenna resonating at 5.5GHz shows that the patch area is reduced by 58.15% while the volume of the antenna is reduced by 81.5%.

In this article, investigation has been carried out on Y‐shaped patch antenna to produce triple‐band for wireless applications. The corrugated Y‐shaped patch antenna is considered to produce low reflection coefficient with high gain at the triple‐bands. The corrugated Y‐shaped patch antenna is resonates at 4.19 GHz (4‐4.43 GHz), 8.79 GHz (8.61‐9.01 GHz), 13 GHz (12.6‐13.6 GHz) frequencies with reflection coefficient of −29.26 dB, −34.87 dB, −40.37 dB and gain 5.01 dBi, 5.42 dBi, 7.46 dBi, respectively. The proposed corrugated Y‐shaped patch antenna works three frequency bands at radio communications, satellite communications, and aeronautical radio navigation applications, respectively.
