Microstrip circular antennas operating at 900 MHz and 1.8 GHz
The use of microstrip printed circular antennas is an alternative approach. These antennas have low profile and can be easily connected to the back side of the handset, providing a nice-looking and compact device. In addition, they are light, compact and easy to fabricate In this paper, antennas of this kind were developed and measured, both at 900 MHz and 1.8 GHz. Essential characteristics for the implementation of these antennas were the low cost of fabrication (by using cheap substrate material), achievement of a radiation pattern with high front-to-back ratio, in order to significantly reduce the amount of electroinagnetic radiation to which the user would be exposed, and reflection coefficient and efficiency, similar to those of monopole antennas
