In this article the radiation performance of coaxial feed dual band dual print microstrip patch antenna using Electromagnetic simulation tool IE3D (Integral Equation Three-Dimensional) and CST-MWS (Computer Simulation Technology Microwave Studio) is offered and discussed. The attempt is made to compare the antenna parameters such gain, impedance bandwidth and radiation pattern from both the Electromagnetic Software. It is observed that both the software has their own pros and cons. However, the features available from the CST make it more feasible in comparison to IE3D. With the presented geometry a wide impedance bandwidth 5.62GHz (1.86-7.48GHZ) with sustained gain is achieved. The antenna radiation parameters are also found as desired. A brief comparison of various EM software is also given for the interest of the readers.

AbstractA low profile Circular Microstrip Patch Antenna (CMPA) with radius 5 mm has been designed to generate two resonant frequency bands that can be used for WLAN 5.2 (5.15–5.25) GHz, Wi-Fi (5.725–5.850) GHz and Dedicated Short-Range Communications (DSRC) (5.85–5.925) GHz application bands. The designed antenna has been slitted with two slits and a stub has also been attached resulting in an additional resonant band alongside the primary resonant band. Also, primary resonant frequency shifted from 7.22 GHz to 5.87 GHz yielding about 18.7% antenna miniaturization. Frequency bands generated by the designed antenna are (5.15–5.25) GHz and (5.71–6.01) GHz having peak gain 2.3 and 4.9 dB with broadside radiation pattern. A square shape FR4 substrate having dimension 32 × 32 × 3.2 mm3 and very thin copper sheet for radiating patch and ground has been used in the proposed antenna, which can fulfill the requirement of smaller antenna with dual band application. Simulation software HFSS ver.13 has been used to design and analyze the proposed antenna. Very good matching has been obtained between simulated and measured results.

A dual band microstrip patch antenna integrated with pinwheel-shaped electromagnetic band-gap (EBG) structures is proposed. The patch antenna consists of a pair of spiral slots on the patch and is fed by using coaxial line. Its full-wave simulation predicts dual bands from 4.43 GHz to 4.56 GHz and from 4.96 GHz to 5.1 GHz in the C-band. The designed EBG with eight pinwheel-shaped slots addresses smaller frequency drift compared with the traditional square mushroom-like EBG when applied to the patch antenna. With the help of designed EBG structure, the impedance bandwidth, radiation efficiency, and gain of the patch antenna are improved significantly. The 10 dB impedance bandwidth is extended by 3.4% and 6.5% at the low- and high-frequency bands, respectively. The radiation efficiency is increased by 5% and 17.8%, and the realized gain is enhanced by 1.87 dB and 1.56 dB at 4.57 GHz and 5.06 GHz, respectively. The designed EBG structure may have many applications in other types of planar antennas.

Parasitic Patch

The paper presents a novel dual-band patch working at GSM band and S-band. The patch encompasses a rectangular radiator coupled with a parasitic patch in the coplanar region and a split ring resonator in the ground region. The patch is analyzed numerically and is synthesized using the HFSS simulator. Finally, the performance characteristics of the model are measured and are compared with numerical and simulated results. The patch gives two different bands at 950MHz and 2.3GHz and gives -10dB impedance bandwidth in the lower band from 950MHz -1GHz and higher band from 2.275GHz – 2.325GHz. The patch also accomplishes a gain of 4.74dBi in the effective band 1 and 4.02 dBi in the operating band 2.

At 2.919GHz the impedance bandwidth is improved by 25.4MHz and return loss is reduced by 19.564dB. For verifying that the proposed metamaterial structure possesses Negative values of Permeability and Permittivity within the operating frequency ranges, Nicolson-Ross-Weir method (NRW) has been employed. For simulation purpose CST-MWS Software has been used.

Good Agreement

In this paper, a dual-band generation in rectangular microstrip patch antenna (RMPA) using a superstrate metal ring has been proposed. In this configuration, a metal ring is placed above the rectangular patch with the support of two dielectric posts. The metal ring behaves as a superstrate layer and resonator for the lower band, the other band is generated by microstrip patch and hence the combined configuration metal ring and patch gives dual-band characteristics. The lower band resonates at 9 GHz with an impedance bandwidth of 6.8% and higher band at 11.35 GHz with impedance bandwidth of 3.1%. The co-polarized peak gain values at these frequencies are 8.2 dBi and 10.1 dBi respectively. This may be used in applications like airborne and naval-radar. The prototypes are fabricated using commercially available dielectric substrate (RT-Duriod r = 2.2 and thickness h =1.6 mm). The measured results show good agreement with the simulated predictions.
