“…The antenna was fed by coplanar waveguide and gives 10 dB impedence bandwidth of 250 MHz at 2.44 GHz and about 22% from 5.13 to 6.38 suitable for WLAN and WAVE 5.9 GHz applications. A dual frequency rectangular microstrip patch antenna [2] had been proposed. The single layered antenna had been designed to resonate in dual frequency mode and achieved reduction in patch size up to 71%.The design was obtained by cutting rectangular slots at two sides of the patch.…”

A compact dual band microstrip patch antenna is designed for C (4-8 GHz) band and X (8-12 GHz) band applications. The proposed antenna consists of a rectangular patch having four U-slots and one I-slot with H-shaped DGS (Defected Ground Structure) . The antenna has overall size of 25mm by 23 mm and gives bandwidth of about 140 MHz from 5.85 GHz to 6 GHz and of about 1.21 GHz from 7.87 to 9 GHz at resonating frequency of 5.9 GHz and 8.8 GHz respectively with DGS. The antenna without DGS mainly resonates at 6 GHz and 8.7 GHz. The antenna with DGS has return losses -16.29dB at 5.9 GHz and -18.28 dB at 8.8 GHz, gain 1.2 dBi for 5.9 GHz and 4.4 dBi for 8.8 GHz. This antenna has been analyzed using IE3D electromagnetic solver.

“…Microstrip antennas are famous due to small size, low profile, light weight, flexibility, and there compatibility with integrated circuits [1]. Multiband microstrip antennas are in demand for many applications such as wireless local area network (WLAN) and satellite communications [2,3]. Simple compact with defected ground plane [4], multifrequency microstrip antennas with a single feed are required in radar and communications system such as synthetic aperture radar, dual-band GSM/DCS 1800 mobile communication system, global positioning systems satellite communications, and in VSAT applications [5].…”

In this letter, a three U‐shaped slot loaded rectangular patch with defected ground plane antenna has been analyzed. The antenna shows multiresonance. The resonance frequencies of single layer patch are found to be 9.75 GHz, 11.55 GHz, 12.15 GHz, 13.49 GHz, and 14.3 GHz and its frequency ratio are found to be f2/f1 = 1.18%, f3/f2 = 1.05%, f4/f3 = 1.11%, and f5/f4 = 1.06%, respectively. The bandwidths of this proposed antenna are found to be 2.88%, 0.0%, 5.59%, 4.96%, and 1.53% and the respective gains are 0.46 dB, 4.02 dB, 4.28 dB, 4.85 dB, and 3.78 dB, respectively. Introducing three U‐slots in the rectangular patch with three parallel slots loaded on the ground plane, near about 30% of size reduction has been achieved. All the simulation results obtained from IE3D which are in good condition. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:124–128, 2016

“…A U-slot patch antenna on flame retardant 4(FR4) substrates for radio frequency identification (RFID) systems is reported in [10]. Rectangular slit-loaded patch with 70 % size reduction has been achieved in [11]. By inserting dumbbellshaped defected ground structures (DGS) and slots on the rectangular patch, 91 % size reduction with blocking of surface waves is achieved as in [12].…”

This paper demonstrates the design and result of a low profile wide band miniaturized slit-loaded microstrip patch antenna with defected ground structures (DGS) for wireless applications. The proposed antenna is coaxially probe fed that operates at 5.5 GHz and has an array of rectangular slits etched on the patch and a pair of square-shaped dumbbell DGS loaded into the ground plane. The bandwidth of the slit-loaded microstrip patch antenna is 12 %, whereas it increases up to 17 % when DGS is loaded into the ground plane. The proposed compact antenna resonates at multiple frequencies between 1 and 9 GHz frequency range, at 4.84, 5.96, and 6.34 GHz with a bandwidth of 330, 150, and 460 MHz having return loss of −17.2, −18.5, and −27.3 dB, respectively. All the antenna geometries in this paper are simulated using an electromagnetic simulation tool named CADFEKO. The proposed multiband antenna finds useful applications with an improved performance simultaneously in W-LAN (4.8-5.8 GHz) and satellite communication bands (5.92-6.42 GHz). The plots of various antenna parameters such as return loss, voltage standing wave ratio (VSWR), gain, and bandwidth of the proposed antenna have been observed with and without DGS and the analysis of the simulated results shows that the proposed slit-loaded antenna with DGS is more efficient than conventional rectangular microstrip patch antennas (CRMPA) in terms of bandwidth of operation and miniaturization.
