This is also a concrete achievement of the UK Summer Abroad Programme in University of Greenwich as three of the seven students were part of the programme, this programme definitely broadens their horizon,
This year, kareem samheh will present his paper titled: "A COMPACT SIW METAMATERIAL COUPLED GAP ZEROTH ORDER BANDPASS FILTER WITH TWO TRANSMISSION ZEROS"
This paper presents a new compact metamaterial bandpass filter based on coupled gap composite right left handed transmission line resonator using substrate integrated waveguide to become low loss. The filter size is only 20 ×15 mm2 at center frequency (6.8 GHz). Moreover, the filter was designed to demonstrate a zeroth order at 6.8 GHz with two transmission zeros; the first one is at -44 dB and the second one is close to -50 dB in a high selective characteristics (less than only 300 MHz from center frequency). The paper exhibits the equivalent circuit model, 3D full wave simulation and fabrication measurement results. Good agreement between the presented data is achieved.
And Ghadeer and Mahmoud Reda will present their papers titled: COMPACT UWB LPF BASED ON UNI-PLANAR METAMATERIAL COMPLEMENTARY SPLIT RING RESONATOR
This paper presents a compact ultra-wide low pass filter based on a uni planar configuration of metamaterial complementary split ring resonator. The filter has insertion loss close to 0 dB over the frequency band DC up to 10.8 GHz. Also, the filter has the advantage of small size (18 mm × 7 mm) whose length is only about 32% of the guided wave length at mid frequency. Different order types of this filter are discussed in the paper. The filter design is explained and its performance is validated using full wave simulation and experimental measurements. Very good agreement between the two results is achieved which confirm the theoretical design.
And Abdullah Al-Mohamadi , and Abdullah Moustafa will present their papers titled: DUAL NOTCHING OF UWB ANTENNA USING DOUBLE INVERSE U-SHAPE COMPACT EBG STRUCTURE
This paper presents an ultra-wide-band monopole antenna integrated with a new configuration of electromagnetic band gap structures (EBGs). The operation frequency band of the ultra wide band antenna is 3.1 GHz-10.6 GHz whereas the dual rejected bands are 5.2 GHz and 5.8 GHz. These two notched bands are for wireless local area network. The new proposed EBG structure is composed of double inverse U-shape slotted patch and edge-located via. Using this new EBG, a high notching selectivity can be achieved for both bands. Compared to conventional mushroom like EBG structure, the proposed configuration of the EBG structure can reject dual band instead of single band and have smaller size by 72 %. The detailed theoretical study supported by electromagnetic full wave simulations and confirmed by experimental measurements is introduced.
And Motazz Naser , and Nour El Sobky will present their papers titled: METAMATERIALS INSPIRED DUAL-WIDE BAND CPW-FED ANTENNA USING SPLIT RING RESONATOR
This paper presents a metamaterial inspired dual-wide band CPW-fed antenna using split- ring resonator structure. The antenna design is inspired from conventional circular monopole antenna to two split rings resonators. The antenna geometry was optimized to achieve two wide bands; the lower band covers the band 2.65 GHz to 3.25 GHz whereas the higher band covers the band 5 GHz to 7 GHz. The antenna dimensions were optimized for compact size (30 mm × 30 mm). The antenna radiation pattern was kept as omnidirectional in both bands. Full wave simulation and experimental measurements results are introduced with good matching between them.
