Composition of L-shaped grounded reflector with planar monopole array to explore fan-beam antenna characteristics for DECT, 3G and 4G wireless applications

In this contribution, a fan-beam antenna employing a non-parasitic reflector in a grounded manner is introduced. A fan-beam antenna is achieved by 13 elements conventional planar monopole array antenna. This concept is performed by combining planar monopole antenna as an array and non-parasitic L-shaped reflector. This array element has an Omnidirectional pattern and these characteristics are allowed to control the antenna H-plane 3 dB beam-widths for the desired angle by grounded reflector shape. The antenna input impedance matching bandwidth is approximately 1550-2550 MHz when simulated. The antenna has broad band input impedance band width, good radiation patterns and proper peak gains in DECT, 3G and 4G bands. This type of antenna can be constructed easily, cheaply as well as being light weight for installation.
