Dual Band Aperture Coupled Stacked Microstrip Patch Antenna for WLAN
نویسنده
چکیده
This paper presents a dual band aperture coupled stacked microstrip antenna with the introduction of an air gap 3 mm between the ground plane and the upper layer substrate for WLAN applications. The nominal antenna has – 10 dB return loss bandwidth of 134.8 MHz and 384.9 MHz at lower band resonant frequency of 3.905 GHz and upper band resonant frequency of 5.36 GHz respectively. The gain of the antenna is greater than 5 dB, also the directivity is greater than 5 dBi and VSWR value is less than 2 for both the operating frequencies, which makes it a suitable choice to be used at the frequencies bands of WLAN.

In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...
متن کاملDual - and Triple - Band U - slot Microstrip Patch Antenna for WLAN Applications
In this paper, Microstrip patch antenna fed through an aperture coupled 50Ω microstrip line is designed for dualband and tripleband applications by cutting U-slots in the patch. When a U-slot is cut in the patch, a notch is introduced within the matching band, results in dualband antenna. If another U-slot is cut in the same patch, antenna becomes a tripleband antenna. For better coupling apert...
