Parametric study of the low-profile foam dielectric over-the-shoulder antenna based on coupled patches technique

The paper presents a parametric study of the over-the-shoulder foam dielectric antenna based on coupled patches technique for 380 ÷ 390 MHz frequency band. Despite having a very low profile (0.0072 λ0), it shows the satisfactory radiation efficiency and very good immunity from the negative influences of the human body. Influence of the antenna elements to the radiation efficiency, gain, frequency bandwith and impedance matching is evaluated by means of the parametric study.
