A Low-Profile Printed Planar Phase Correcting Surface to Improve Directive Radiation Characteristics of Electromagnetic Band Gap Resonator Antennas

We present the design of a multibeam reflector antenna fed by a multifeed dual-band electromagnetic band gap (EBG) antenna to achieve a high-gain multispot coverage for space applications. First, we design a dual-band EBG antenna in monofeed configuration. This antenna is composed of double-layer frequency selective surfaces (FSSs) arranged in the longitudinal direction and a square horn as a feed. Then, the same antenna in multifeed configuration is studied, and the results are compared to those obtained in monofeed configuration in order to emphasize the problem of coupling, generally encountered in multifeed configuration. Consequently, filters are used in order to reduce the parasitic interferences and obtain good radiation characteristics. As shown in this paper, the same EBG phase center is obtained in both frequency bands. Finally, we have studied the whole system composed of the offset reflector and the multifeed EBG dual-band antenna. An edge of coverage (EOC) gain higher than 42 dBi and sidelobes levels lower than −18 dBi are obtained over all spots.

Profile Characteristics

Flexible dual band dipole antenna incorporates with Electromagnetic Band Gap (EBG) to improve the well-known low profile characteristics of dipole antenna. The antenna operates at 2.45 GHz and 5.8 GHz which is printed on Fast film with 0.13 mm thickness. While the EBG is designed at 5.8 GHz by using Arlon AD350 with 1.016 mm thickness. EBG works as a ground plane for the antenna and helps by improving the realized gainandradiation pattern. Besides, EBG also act as a filter as the resonant frequency of the antenna is close to the EBG band gap. The 2.45 GHz of is eliminated while the performances of antenna at 5.8 GHz is improved. Thus the realized gain is increased up to 6.86 dB and the back lobes is clearly reduced. The designs of dipole antenna with EBG application such as Wifi and others on-body communication devices.
