Design and simulation of dense dielectric patch antenna for wireless applications

Wireless communication devices and techniques are proliferating, improving and expanding every day. The development of such device must meet specific requirements: small size, light weight, low cost, and attractive appearance. There are many techniques to improve the characteristics and performance of antennas. A dense dielectric patch in a circular shape for the antenna is proposed here for reduced size copy of the whole. The beneficial give useful applications in cellular telephone and microwave communications. This paper presents the design and simulation of miniaturized single-band dense dielectric patch antenna for wireless applications. The designed antenna is resonating at 3.86 GHz yielding a return loss of about -25.9 dB which is suitable for Wi-MAX, public and private mobile applications. The simulation has been carried out using Agilent Advanced Design SystemEM simulator.
