Omnidirectional high-gain wide slot antenna array for mobile phone base station

This paper proposes an omnidirectional high-gain slot array antenna for mobile phone base station. The advantages of this proposed antenna are low profile, light weight, and easy fabrication and installation. Moreover, it provides not only the moderately high gain but also the omnidirectional pattern, which more appropriate for mobile phone base station. The half-power beamwidths in E-plane is around 24 degrees, while its radiation pattern is similar to the circle or omnidirection. The paper also presents the design procedures of a 1×4 array antenna using slot antennas associated with two side-wings for increasing its gain. A Computer Simulation Technology (CST) software has been used to compute the reflection coefficient (S₁₁), radiation patterns, and gain of this antenna. The bandwidth, at S₁₁ (-10 dB), is which can be well utilized for 3G base station, with a gain around 9 dB.
