In this paper, an inverted F antenna works in the 5.8GHz frequency band is proposed. On the platform of Ansoft HFSS14, the antenna’s return loss reaches -51.97dB at the center frequency 5.8GHz and the relative bandwidth is about 22.4% when the return loss is less than -10dB. Also,the size of the antenna is only 18mm.15mm.

Compared with the existing antenna works in the same frequency band, the inverted F antenna proposed has a lower return loss and smaller physical size. The new designed antenna can be applied to the RFID system of road tolls and container management, which have certain values for application. Abstract: In this paper, a new ultrahigh frequency circularly polarized microstrip antenna using in RFID reader is proposed. The proposed antenna has a simple structure, it has non-symmetrical rectangular corner truncated square patch, ground plane and a probe feed. To achieve good circular polarization(CP) radiation characteristics, it uses air as the dielectric layer.

Simulation results of a constructed prototype with the center operating frequency at 923 MHz showed that the antenna has a return loss S11 of about −24 dB, a gain level of about 9.48 dBi. The antenna has good impedance and radiation characteristics over the required bandwidth, 920-925 MHz (Chinese UHF RFID band). Abstract: This paper researches how the various iterations affect the characteristics of Minkowski fractal microstrip patch antenna. A 2-itration Minkowski fractal reader antenna is designed.

In order to increase antenna bandwidth, the structure of a novel modified antenna is presented to operate at 2.45GHz with the return loss of -35.15dB and bandwidth of 180MHz, the maximum gain of which is 7.83dB. Besides, with its size of 30mm ×30mm, this antenna area is decreased by 43.75% and the width is decreased by 25% compared to normal square patch antenna. The simulation results show that it has a good size-reduction feature that can well meet the requirement for handheld RFID reader under certain size and characteristics. Abstract: The Vivaldi antennas are widely used in many wide band electronic systems for its good performances. This paper designed and simulated two kinds of Vivaldi antennas for wide band passive radar applications, which are the antipodal Vivaldi antenna fed by strip line and antipodal Vivaldi antenna fed by microstrip line. The specific design parameters and the radiation performances of each kind of vivaldi antenna are provided over the operating frequency range of 3GHz to 11GHz. Furthermore a circular antenna array with six Vivaldi antenna elements fed by microstrip lines was also simulated to obtain its radiation performances over the operating frequency range of 3GHz to 8GHz.

The simulation results demonstrate the designed Vivaldi antennas have acceptable performances of voltage standing wave ratio (VSWR), patterns and gains, so they can be used in practical wide band radars. Abstract: A CPW-fed microstrip monopole antenna which is conformal to a conical surface is presented in this paper. It has a simple structure printed on a substrate with dielectric constant of 2.55 and thickness of 0.2mm. By the aid of electromagnetic simulation software of CST Microwave Studio, the main influencing parameters of the antenna are simulated and analyzed, the difference between planar antenna and conical conformal antenna has been discussed, and the optimized physical model has been achieved. The simulated result shows the proposed CPW-fed conical conformal antenna has a broad bandwidth property that covers from 6.2 to 20GHz(VSWR 2), and it is suitable for wideband radar applications. Abstract: A printed ring-shaped monopole antenna fed by coplanar waveguide for use in the dual-band wireless communication system has been presented and investigated. By adding some branch strips inside the ring and changing its size, as well as the further optimization, the proposed antenna could work effectively within the scope of 2.4-2.484GHz and 5.15-5.825GHz frequency band.
