The analysis and design of the proposed antennas is designated for receiving voice signals from Radio in general are out-of-prominent antennas and smaller indoor antennas, in this research, the authors aim to design and analyse an antenna with a simple design, a small dimension efficient, very easy installation, cheap and meet the antenna characteristics to support the movement in combat training within the Army. The antenna to be discussed is a monopole antenna Arrays with a minimalist shape that works at frequencies between 350MHz - 480MHz by adjusting the length of the horizontal elemental Active distance between the outer and inner to get the impedance matching. In order to obtain a unidirectional pattern, a metallic plane reflector is placed at a distance of about λ/4 from the array board: predicted gain (11 dB for 5 ?1 array and 15 dB for 9 ?1 array) and bandwidth (around 600 MHz) are larger than for conventional micro strip patch arrays having similar board dimensions. the proposed antenna has been numerically analysed for wireless communication systems. © Published under licence by IOP Publishing Ltd.
