In this paper, a high gain stacked patch antenna is proposed in this two patches are arranged one above the other in a single substrate to achieve dual band characteristics for high gain frequency selective surface has been used.Abstract:
Circularly polarized antennas are used mostly due to the advantages over linearly polarized antennas like Mis-alignment and cross-polarization etc. In this paper, a high gain stacked patch antenna is proposed in this two patches are arranging one above the other in a single substrate to achieve dual band characteristics for high gain frequency selective surface has been used. The proposed antenna operates at band of 2.4 GHz for the application of WLAN, second antenna operates at two bands one is 2.2GHz and other at 3.6GHz. Simulation results evaluated in term of return loss, bandwidth, radiation pattern, directivity, gain and axial ratio. Gain of the antennas is 3.28 dB for trimmed square patch and 2.4 dB for inset feed antenna and 2.8 dB for centre feed antenna. For proposed antenna gain is 8.9dB at 2.2GHz and 3.9dB at 3.6GHz. Circular polarization antennas are one such a kind to their applications in satellite communications, Navigation systems, and mobile communications, proposed antenna can be used in WLAN, Wi-MAX, WPAN and RFID applications. Center frequency can be optimized; further more gain and matching can be obtained by integrating active components like diode, transistor and FET etc.read more
