The development of a compact, lightweight, dualfrequency antenna feed for future soil moisture and sea surface salinity (SSS) missions is described. The design is based on the microstrip stacked-patch array (MSPA) to be used to feed a large lightweight deployable rotating mesh antenna for spaceborne L-band (~1 GHz) passive and active sensing systems. The design features will also enable applica...

Microwave sensors are robust non-contact measurement devices for industrial and vehicular application. Phased array-antenna modules, located in the front-end of the sensor, are often used to enhance the performance of this device. In this paper, a novel 24-GHz microstrip linear array antenna with beam-scanning and signal-amplification properties are presented. The phase shift section is designe...

In this paper, hybrid modeling of Micro-strip antenna is presented. Broadband frequency of operation demonstrated by single geometry .for broadening the bandwidth and maximum directional gain (6.6dBi 8dBi) gap-coupled multi-resonator loaded on parasitic and active patch. The geometry of a single probe fed rectangular Micro-strip antenna incorporating a slot and gap coupled with parasitic and ac...

A small size dual-band antenna for integration with 5-6 GHz RF/Wireless communication systems is presented. The size and structure of the antenna are designed for integration with a RF printed circuit board of a given size (thickness=1.36mm=0.045λ), metallization structure (4-level of metalization) and material properties (FR4, εr=3.78, loss tangent=0.01). It is capacitively fed by a coplanar w...
