Microstrip patch antennas are widely used in modern day communication devices due to their light weight, low cost and ease of fabrication. In this paper, we have designed a Microstrip Patch Antenna and array of patch for 2.45GHz for Wireless Local Area Network (WLAN) applications using antenna simulation software. The designed antenna consists of rectangular radiating patch on FR-4 (lossy) subs...

The digital beamforming antenna array is one of the most important components in wireless communication systems used in defence applications to improve the system capacity and spectral efficiency. The pattern synthesis of active antenna array is required in many defence applications like radar, satellite communication, sonar, mobile communication etc., where interference signals are considered ...

In this work, we propose a novel strategy of adaptive sparse array beamformer design, referred to as regularized complementary antenna switching (RCAS), swiftly adapt both configuration and excitation weights in accordance the dynamic environment for enhancing interference suppression. order achieve an implementable design reconfiguration, RCAS is conducted framework switching, whereby full ape...

• We have experimentally investigated the use of adaptive-focusing techniques in the hyperthermia treatment of cancer. Gradient-search adaptive-focusing software developed at Lincoln Laboratory has been implemented on a commercial microwave hyperthermia planar phased-array antenna system at the University of California at San Francisco (UCSF). The system, manufactured by Labthermics Technologie...

A Side Lobe Canceller (SLC) structure is a conventional partially adaptive technique which is used in large adaptive array radars. If a desired signal has long time duration in comparison with the SLC adaptation time, signal components may be cancelled. So, this paper presents a modified SLC which eliminates desired signal cancellation problems and allows using an unconstrained adaptive algorit...

In this paper novel reflectarray antenna elements are proposed using aperture-coupled dielectric resonator antenna structures. Using these new structures, wide phase range and wide frequency bandwidth (up to 28.5%) with parallel and linear phase curves are obtained. In each case, an array consisting of 289 elements was simulated using the finite integration technique (FIT). The arrays exhibit 3...
