A single feed compact microstrip antenna is proposed in this paper. Two L slits are introduced at right side of the patch. For the proposed antenna resonant frequencies are obtained at 3.48 GHz, 4.34 GHz and 5.65 GHz with bandwidth of 19 MHz, return loss –20.2 dB, 42.6 MHz, return loss-30.5 dB and bandwidth of 39.2 MHz, return loss-20.2 dB respectively.

Ultrasound images are masked by multiplicative speckle noise caused by random interference between coherent backscattered waves. This paper presents an efficient algorithm for real-time speckle cleaning filter of ultrasound images and its VLSI implementation in FPGA. The algorithm presented here implements a regular, tunable filter with an optimized(More)
A single feed compact microstrip antenna is proposed in this paper. L slit is introduced on the right edge of the patch to study the effect of the slit on radiation behavior with respect to a conventional microstrip patch. dB respectively. The antenna has been reduced by 63 % when compared to a conventional rectangular microstrip patch. The characteristics(More)
In recent years, great interest was focused on microstrip antennas for their small and good performance. With the continuous growth of wireless communication communication equipment, there are higher and higher demands feed single layer compact rectangular microstrip antenna application is proposed in this paper. Two L slits are introduced at edge of the(More)
