Teardrop-shaped feed probe provides gradual change of field from coaxial transmission line into microstrip substrate. Produces cicularly polarized beam with suitable edge taper to illuminate reflector antenna. Microstrip array is cluster of 7 subarrays containing total of 28 microstrip patches. Lightweight array of microstrip antenna elements designed to transmit and illuminate reflector antenna with circularly polarized radiation at 1,545 to 1,550 MHz and to receive circularly polarized radiation at 1,646 to 1,660 MHz. Special impedance-matching probes help reduce feed complexity. Wideband Microstrip Antenna-Feeding Array The results show that the VSWR of this RFID microstrip antenna is relatively small in the vicinity of 922.5 MHz, the gain is 2.1 dBi, which can be widely used in China’s UHF RFID communicating equipments. Combining with a new ceramic material, a 925.5 MHz RFID microstrip antenna is designed, which is optimized and simulated by HFSS software. In order to solve the problems above, a method combining theory and simulation is adopted. The design and simulation of UHF RFID microstrip antennaĬhen, Xiangqun Huang, Rui Shen, Liman Liu, Liping Xiong, Dezhi Xiao, Xiangqi Liu, Mouhai Renheng, XuĪt present, China has delineated UHF RFID communicating frequency range which is 840 ∼ 845 MHz and 920 ∼ 925 MHz, but most UHF microstrip antenna don’t carry out this standard, that leads to radio frequency pollution.

Simulation and fabrication measurement results show that the designed microstrip patch antenna characteristics can be applied significantly within the industrial, scientific, and medical (ISM) radio band, which is at fc = 2.40 GHz. The wearable microstrip patch antenna design is then fabricated using the FR4 printed circuit board (PCB) material, hidden inside the jeans fabric, and attached to clothing, such as a jacket accordingly.

Precisely, the microstrip patch antenna with the inset-fed edge technique is designed and simulated systematically by using the Keysight Advanced Design System (ADS) software where the FR4 board with the dielectric constant, ɛr of 4.70, dissipation factor or loss tangent, tan δ of 0.02 and height, h of 1.60 mm is the chosen dielectric substrate.
This project proposes the design of a wireless body area network (WBAN) microstrip patch antenna covered by the jeans fabric as the outer layer operating at the center frequency, fc of 2.40 GHz. With all capabilities mentioned the antenna has potential for WiFi/WiMAX, Vehicle-to-Vehicle (V2V), transportable earth exploration satellite, military requirement for land vehicles, and earth stations on vessels applications.Wearable Inset-Fed FR4 Microstrip Patch Antenna Design

The results show transmission coefficient of proposed DNM antenna with metallic presence almost identical to free space across desired frequency bands. The metallic effect on antennas performance also has been investigated by evaluating the mutual coupling and transmission coefficient between two antennas served as transmitter and receiver with presence of car body.
The performance of ECC between four antennas on car body has been investigated in different cases of isotropic, indoor, and outdoor. Simulations and measurements indicated that the proposed antenna features a low mutual coupling ( 9.995), high efficiency (72%-95%), and low on-car detuning over the desired five bands 1.99 GHz to 3.03 GHz, 5.15 GHz to 6.369 GHz, 7.67 GHz to 7.99 GHz, 9.91 GHz to 10.23 GHz, and 11.79 GHz to 12.2 GHz. The reflection coefficient (5n), mutual coupling, effective diversity gain (EDG), envelope correlation coefficient (ECC), and radiation patterns are evaluated for four elements of the proposed antenna placed in four different locations on the car body model. An array of 4 x 6 wire loaded complementary spiral resonator (CSR) unit cells is placed on its reverse side to provide miniaturization and multiband features to the proposed design.
