Conference Paper
In this paper, a compact four-layer offset-beam X-band triangular grid microstrip array antenna with proximity coupled feed patch element is presented. The feed network is in the lower substrate and the radiation elements are in the upper substrate of the array antenna structure, which is isolated by the ground plane in the middle substrate. The fe...
Article
An enhanced reflectarray (RA) antenna built of elements with reduced reflection phase sensitivity is presented. The proposed unit element is composed of a concentric, multiresonance circular-ring structure with variable sizes. By changing the outer and inner radius of the interior ring in the opposite directions, a reduction in the phase sensitivit...
Article
A microstrip-fed printed monopole antenna having band-notch characteristics is proposed. The full band antenna introduces 2.5-10.6 GHz bandwidth covering the FCC frequency band for UWB applications. Six inverted L-shaped stubs on the bottom of the substrate, which are connected to the radiating patch through via pins, are used to create flexible mu...

 Abstract-In this paper a simple rectangular monopole antenna with variable band-notched function is proposed. The antenna is constructed on a FR4-epoxy substrate by thickness of 1.6mm and εr=4.4. The proposed antenna shows Ultra-Wideband (UWB) characteristics from around 3 up to 10.6GHz for VSWR< 2. Two shorting pins running through the substrate...

In this letter, a simple rectangular monopole antenna with variable band-notched function is proposed. The antenna is constructed on an FR4-epoxy substrate with thickness of 1.6 mm and ε<sub>r</sub> = 4.4. The proposed antenna shows ultrawideband (UWB) characteristics from around 3 up to 10.6 GHz for . Two shorting pins running through the substrat...
