RADIATION PROPERTIES OF HETEROGENEOUS ANTENNA ARRAY

The paper presents the improvement in the performance of eight element microstrip antenna array. The overall bandwidth of the proposed microstrip antenna array is equal to 85.74 % as compared to 4.98 % of the conventional antenna array. The proposed microstrip antenna array is producing good reduction in mutual coupling values at the resonant frequency of 5.53 GHz. Moreover, the radiation properties of conventional antenna array are improved with good reduction in power radiated in the undesired direction. The proposed microstrip antenna array is producing a healthy size reduction of 47.19 %. FR-4 glass epoxy substrate is used as dielectric substrate which has a dielectric constant of 4.2 and loss tangent of 0.0245. The microstrip antenna arrays are designed using Mentor Graphics IE3D software.

Element Array

A printed director antenna with compact structure is proposed. The antenna is fed by a balanced microstrip-slotline and makes good use of space to reduce feeding network area and the size of antenna. According to the simulation results of CST MICROWAVE STUDIO software, broadband characteristics and directional radiation properties of the antenna are explained. The operating bandwidth is 1.8 GHz–3.5 GHz with reflection coefficient less than −10 dB. Antenna gain in band can achieve 4.5–6.8 dBi, and the overall size of antenna is smaller than0.34λ0×0.58λ0. Then the antenna is developed to a two-element antenna array, working frequency and relative bandwidth of which are 2.15–2.87 GHz and 28.7%, respectively. Compared with antenna unit, the gain of the antenna array has increased by 2 dB. Thus the proposed antenna has characteristics of compact structure, relatively small size, and wideband, and it can be widely used in PCS/UMTS/WLAN/ WiMAX fields.

Microstrip Antenna Array

In this paper two element microstrip antenna array with dumbbell shaped defected ground structure (DGS) is on reduction of mutual coupling is presented. The proposed of DGS antenna is simulated by an soft HFSS simulation software. this work is obtain a miniaturized microstrip patch antenna array using DGS for S Band is 2.2GHz.Initally the patch antenna array is designed at C band resonates at 5.2 GHz and the proposed of DGS is integrated in the ground plane of patch antenna for size reduction and this miniaturization is at cost of gain antenna and in order to improve the gain of miniaturized radiator. Patch radiator is further modified to radiation properties, so finally the resonance frequency of an initial microstrip antenna array shifts to 3.75 GHz to 7.15 GHz with the gain of 2.92 dB and its miniaturization performance is up to 63% and its conventional microstrip is successfully accomplished. The prototype antenna is fabricated with the FR-4 substrate and this technique is validate experimentally and measured results with good agreement as stimulated results.
