In this paper, a high gain array antenna, consisting of two layers, using Giuseppe Peano Fractal Configuration as its radiation elements is designed, fabricated, and measured. This fractal array antenna consists of 8 ×8 fractal elements, is fed by a microstrip corporate feeding network, and works at frequency of X frequency band (10.0GHz). Both simulation and measurement show, the proposed fractal...
The paper presents the design of a linearly polarized single-layer reflectarray which employs a fixed-size circular ring with a variable-length open-circuited stub run around it as a phasing element. To achieve a slow phase slope, a thick foam material is used to support this element developed on a thin substrate. Investigations are performed to achieve a linear reflection phase as function of the...
In this paper, a new printed dipole array omnidirectional antenna is proposed. Its bandwidth is enhanced by using symmetrical and two-section impedance matching feed circuit. The simulated and experimental impedance bandwidth with VSWR <; 2 are around 19% or from 668MHz to 808MHz. The gain is large than 6dBi within the bandwidth. The fluctuation in H-plane radiation pattern is less than 3dB.
The paper describes the method to broaden the bandwidth of circular polarized patch antennas in different forms, including single patch antenna, double-layer patch antenna and antenna array.
A novel design of corporate fed four element rectangular microstrip array antenna (FRMAA) has been proposed for triple band operation at X-band frequency. By increasing the number of array elements from four to eight, the triple band operation can be converted into dual bands. This overall impedance bandwidth is 1.16 times more than the impedance bandwidth of FRMAA with improved broadside radiation...
