A four port diversity microstrip patch antennas for WLAN was designed, working in the 5.180 to 5.220 GHz frequency. Port diversity was carried out by changing the orientation of the port as of 90° between each consecutive port to reduce mutual coupling and reduce overall dimensions of the antenna. Dimension of realized antenna was 49.48 mm ×(More)
Microstrip antenna has a small gain, bandwidth and efficiency. To overcome those weaknesses, this paper focused on a design of multilayer parasitic substrate for enhancing antenna gain. The distance between first layer parasitic and second layer parasitic had been optimized to maximize electromagnetic coupling and improve antenna main lobe. The microstrip(More)
Tapered slot vivaldi antenna is an antenna type that has a very wide bandwidth. With that performance, tapered slot vivaldi antenna can cause interference if it is applied on a weather radar that requires a fairly narrow bandwidth only. Therefore, this paper will discuss the design and simulation to narrow bandwidth of the tapered slot vivaldi antenna in(More)
An adaptively compensated multiband spectral subtraction (MBSS) is presented in this paper. In this research, the adaptive compensation in the MBSS utilizes artificial neural network. The purpose of this compensation is to improve the quality of speech signal after denoising of MBSS step. This compensation is calculated adaptively depend on the MBSS(More)
