The study proposes a novel Approach of Circular Microstrip Patch Antenna for Multi-Band. Proposed Dimension is (40×30×1.6)mm^3 on the FR-4, Which has ?_r equals(4.3) and Loss tangent (0.002). Both Patches Grounds are Copper Material With Thickness (0.035 mm) Five Bands Achieved, At Resonance Frequencies (9.658 GHz), (11.68 (16.054 (21.28 (29.704 GHz) Respectively. This Operates In Wireless Appl...

The ITU Radiocommunication Assembly, considering a) that one of the principal limitations in achieving greater utilization of the RF spectrum and geostationary orbit for the fixed-satellite service (FSS) is mutual interference among satellite networks operating in common frequency bands and serving the same or adjacent geographical areas; b) that inter-satellite network interference protection ...

In this paper, we describe the analysis of the TerraSAR-X high-resolution spotlight mode radar data in comparison with in situ measurements, optical imagery and ALOS PALSAR L-band radar data, for the purpose of investigating surface and subsurface features associated with ancient stones at Nabta Playa, Egypt. Many of the structures observable in the field and from high-resolution satellite opti...

A reduced ground plane diamond shaped multiband microstrip slot antenna is proposed. The antenna is designed with two symmetrical slots to form the diamond shape and the patch is fed with a microstripline. The slots make the antenna to have multiple resonances to operate in the frequency bands of 2.15 GHz to 7.8 GHz with a peak gain of 6.09 dB at 6.83 GHz and above 2 dB in all operating bands a...
