An ultra-wideband antenna with a conical ground and trident inset feeding structure is presented. The consists of U-shaped monopole designed on printed circuit board three-dimensional aluminium mold, serving as the ground. Low frequency (<; 1 GHz) matching achieved feed branches by inserting them into monopole. Simulation studies show that proposed 3-D outperforms horizontal or flat-lying model...
Simple internal multiband monopole antenna with low SAR for most of wireless mobile communication applications is presented in this paper. The proposed antenna is an unequal arms monopole antenna with a meander strip in the other substrate side. The antenna has a simple structure and is sufficiently small in size to be easily fit on the housing of mobile or USB dongle with size 18 × 15 × 0.8mm3...
In recent years, many small internal antennas have been designed for mobile handsets in [1, 2]. Many monopole-type antennas have been investigated because they operate at the lowest resonant mode which is helps to reduce their size. A loop-type antenna, on the other hand, has rarely been applied to small antenna design because the lowest resonant mode is a parallel resonance (anti-resonance). C...
