Abstract
In this paper, we propose a new design procedure for printed dipole array antennas. Applications of these arrays are devoted to wireless communication systems, mainly base stations and beam steerable antennas. All the designs have been developed at the frequency of 3 GHz. This structure is chosen in order to enhance the gain and minimize the backside radiations of an antenna array with a very simple feeding.
Highlights
The explosive growth of the wireless communications industry has led to an increasing demand for low cost, low profile and integrated antennas
Yagi arrays have been utilized in industrial, scientific, and medical (ISM) applications at 2.4 GHz, high performance radio local area network (HIPERLAN) and IEEE802.11a (IEEE802.11n) WLAN bands between 5 - 6 GHz
We propose a new design of printed array for base station and steerable beam antenna
Summary
The explosive growth of the wireless communications industry has led to an increasing demand for low cost, low profile and integrated antennas. Features and advantages of the proposed antenna in this paper include: 1) the driven element is a dipole not a patch; 2) the antenna achieves high gain over a wide frequency range without the use of active components; 3) the antenna’s characteristics can be controlled by changing various parameters in the design resulting in making the antenna suitable for a wide range of wireless applications; 4) not expensive; 5) light and 6) low profile. The feeding technique is complicated and creates an unbalanced condition for the antenna operation To overcome this problem, we can print the microstrip line and one driver arm on the top of the substrate and a ground reflector with another driver arm and the directors at the bottom side of the substrate. All the designed antennas are manufactured, measured and compared with the simulation
