In this paper, the design and simulation of a compact ultra-wide band (UWB) microstrip antenna with quadruple band-notched characteristics for short-distance wireless telecommunication applications were explored. The design process of the antenna is carried on FR4 substrate with dielectric constant 4.4, loss tangent 0.02, thickness of 0. 8mm and the size of the proposed antenna are 30×20 mm2. The rectangular monopole antenna endures a rectangular radiating patch with chamfered bevel slots on the top side, and a defective ground planed on the bottom side of the substrate. To realize single, dual, triple and quadruple band notch characteristics, slot-1 is created on the patch to achieve first notch at 3.5 GHz, which eliminates WIMAX signal, slot-2 is created on the patch to achieve second notch at 4.6 GHz, which eliminates INSAT signal, slot-3 is created on the patch to achieve third notch at 5.5 GHz, which eliminates WLAN signal and also fourth notch is created at 9.5GHz which eliminates X-band frequency with slot-1 outer length. The proposed antenna is well miniaturized and can be easily integrated with any compact devices. The simulated result shows that proposed antenna gain a good range of UWB from (2.6 GHz to 13.4 GHz).

<span>A metamaterial structure capable of operating as a wide band absorber as well as an AMC reflector is presented in this report. A microstrip patch copper was used as a switch to switch between the two modes. An FR4 substrate was used and the incidental wave angles were varied from 0<sup>0</sup> to 60<sup>0</sup>. Simulations results showed that the absorber was able achieve 96% absorption at 13.05 GHz and 100% absorption at 10.00 GHz and 12.00 GHz. Furthermore, it archived over 85% absorption for the entire X-band frequency range. The AMC reflector also was able to achieve 84.97%, 82.88% and 78.69% for incident angles 0<sup>0</sup>, 20<sup>0 </sup>and 40<sup>0</sup> respectively. Unfortunately, the structure is polarization sensitive.</span>

The Impact

A defected dodecagonal microstrip antenna fed through co-planar waveguide and operating in X-band frequency range(8-12 GHz) is proposed. Characteristic mode analysis is employed in examining the impact of defects on the resonant frequencies and return loss. Contrast in return loss for the suggested antenna with and without defects is dealt through Characteristic mode Analysis. Geometrical aspects of the proposed antenna are 40 mm × 35.5 mm × 0.1 mm. Subtrate material used in design is FR4 with a dielectric constant (εr ) = 4.4 and height (h) = 0.1m. CST Microwave Studio is used to simulate antenna parameters and Characteristic mode analysis. A return loss of -49.5dB at center frequency of 10.12GHz is observed with a fractional bandwidth of 47.6%. Gain of the antenna peaks at 4 dBi in the band of operation.

X Band

A Compact dual slot ultra-wide band (UWB) Antenna for WLAN and X-Band applications is proposed. The projected antenna is designed for the planar ultra-wide band (UWB) antenna and ultra-wide band (UWB) with two band dismissals. The proposed antenna overall size is 30x40x1.6. The antenna comprises of Rectangular patch imprinted on the Flame Resistant (FR4) substrate with 50Ω input impedance. FR-4 is a composite material made out of fiberglass fabric woven with an epoxy pitch cover that is fire safe (self-dousing). "FR" implies fire resistant, and means that the material meets the standard. This patch consists of dual slot one for WLAN and one for X-band Satellite Communication System. The antenna intended with return loss (RL) >= 10db and frequency ranges between 3.1 to 10.6 GHz with VSWR<2. The antenna works for the applications of wireless local area network (WLAN) system (5.15 – 5.825 GHz), X-band downlink (7.25 - 7.75). The ultra-wide band frequency range for these wireless systems causes interference. To reduce the interference, band notching is done. The WLAN and X-Band satellite communication system bands are forbidden by inserting slots in the patch. The proposed antenna is having high gain at the pass bands while a sharp drop at the forbidden bands.

Radar has been widely used for various purposes such as monitoring atmospheric precipitation. For that purpose, it gives more accurate results than satellites do. Previous research has developed navigation radar that alters its functions into an atmospheric precipitation monitoring radar. To improve the development of the radar, an antenna system will be developed in this research. The purpose of developing this antenna is to obtain better data reception results. This antenna is a microstrip rectangular array antenna that works on X-band with a frequency of 9.41 GHz. Microstrip antenna is chosen since it has several advantages such as small dimensions and relatively low costs. The designed antenna gain ≥ 12 dB, bandwidth of 60 MHz, and horizontal polarization. Antenna fabrication produces a microstrip rectangular 16 x 1 array antenna using the mitered bend method at a frequency of 9.4 GHz with a reflection coefficient of -22.8 dB, VSWR of 1.2, gain of 13.21 dB, unidirectional radiation patterns and horizontal polarization.
