This paper presents a passive wireless long-range displacement sensor that is based on the circular patch antenna, and the detecting range of the sensor can be customized. The sensor consists of a chipped circular antenna with two opened rectangular windows, a substrate, and a ground plate with a sloping channel. No bonding between the antenna and the ground plate allows for the chipped antenna to slide along the sloping channel. The channel will drive the current flow on the plate once the chip is activated, increasing the effective electrical length and, consequently, decreasing the resonant frequency of the circular antenna. The sensing mechanism equates the measuring displacement to the relative movement of the antenna with respect to the ground that achieves the measurement of long-range displacement and, thus, the proposed sensor can avoid stress damage to the antenna due to excessive deformation. Three different range sensors were simulated in the the Ansoft high frequency structure simulator (HFSS). The results show that the resonance frequency of the antenna has a linear relationship with the varying chute depth beneath the chip. Three sensors were fabricated, and the experimental results also validated that the sensitivity of the sensor can be adjusted.

Abstract: The evolution of wireless communication system has led path for innovative antenna design specifically in wideband antenna for WiMax application. In this paper design and simulation of microstrip wideband circular patch antenna array operating between 2GHz to 4Ghz is presented. The circular patch antenna is designed to operate at 3GHz line feed and the ground is itched to achieve required wideband characteristics. The simulation is carried out in EM Flow solver, High Frequency Structure Simulator software. For a single patch antenna, the return loss, lesser than -10dB throughout the bandwidth. Later an antenna array is operating between 2GHz to 4GHz frequency is designed and simulated. The return loss is lesser than -12dBi throughout the band and a peak gain is 14.7dBi.

Circular Patch Antenna

In this paper, a circular patch antenna with Coplanar Waveguide (CPW) feed for LTE application is proposed. The proposed antenna design exhibits a decent impedance matching inside the LTE Bands 2.6 GHz. The planar monopole antenna with coplanar waveguide (CPW) feed has been considered here. It has greater advantage over microstrip compose feed lines, low scattering, low radiation spillage, the capacity to successfully control the trademark impedance, and the simplicity of mix. Rogers RT/duroid 5880 is used as substrate having a dielectric constant of 2.2 with a thickness of 1.6 mm and the conducting surface as copper. The proposed antenna obtains a narrow bandwidth in the frequency range of 2.6 GHz. It is suitable for LTE application because of its compact size and less cost to fabrication. The gain and efficiency of this antenna is good. The antenna is designed with the help of High Frequency Structure Simulator (HFSS) software.

Circular Patch Antenna

In this work, an array of circular patch antenna loaded with a partial split ring and a pair of stubs each with same dimensions, on each of the antenna. Patch of the radius (r) = 7.5mm. The split ring is of the width 1.35mm. the split ring not only accounts for a newer operating band, but also tend to reduce the isolation and the stubs are tends to increase the bandwidth which results in change by 44.92% compared to array of antennas without split rings. The substrate dimensions are 55´30´0.8mm3 and the ground of 55´9mm2. The proposed antennas are simulated using high frequency structural simulator and the results compared with the circular patch antenna without split ring resonators. The results obtained clearly show that, bandwidth of circular micro strip antenna without split ring can be enhanced. The proposed antennas may find applications in LTE band 1, 2, 3, 4, 7, 9, 10, 11, 15, 16, 21, 22, 23, 24, 25, 30, 33, 34, 35, 37, 38, 39, 40, 41, 42, 43 GHz covering a broadband width of 2500MHz.

A new small circular patch antenna for ultra-wideband (UWB) applications is presented. By studying this structure, it is shown that the insertion of a slot with the desired length and width in the ground plane, can lead to a large bandwidth. Our antenna, whose dimensions are 18×12×1.58 mm3, was fed by an SMA female connector with characteristic impedance of 50Ω in order to measure the return loss and VSWR and to compare them with the simulation results. The bandwidth obtained from measurements ranges from 3.52 to 13.67 GHz for VSWR < 2 and from 3.26 GHzto14.23GHz for VSWR < 3. The radiation pattern is omnidirectional on most of the operating band. High Frequency Structure Simulator (HFSS) was used for simulation whose results are in good agreement with the measured parameters.

Circular Patch Antenna

Microstrip patch antenna is attractive for various applications due to its easy fabrication, low cost and small size. It simply comprises of a radiating patch and ground plane that are separated by a dielectric substrate. However, the resonance bandwidth of the microstrip antenna is still an issue that needs to be considered in research. This paper aims to enhance the bandwidth of a microstrip antenna or introduce more resonant frequencies within the Super High Frequency (SHF) band. The paper demonstrates empirical results for circular-shaped patch antenna using the High Frequency Structure Simulator (HFSS). It begins by investigating different patch sizes and substrate materials, so that an optimal preliminary design is introduced. Then, different slot shapes are inserted into the patch for significant enhancement of the resonance characteristics. As a result, new ultra-wideband (UWB) antenna designs are presented with bandwidth results reaching 15.5 GHz within the C, X, Ku and K bands. Also, new multiband antenna designs are presented with improved reflection valleys in the Ku, K and Ka bands.
