Reduced size microstrip antennas with different slot and patch shapes are investigated .The ground plane size is 20 X 20 mm and substrate thickness taken to be is 1.6mm which is about the size of atypical wireless card. Detailed simulation and experimental investigations are conducted to understand their behavior and optimize for miniaturized operation. It is shown that the shorting pin makes t...

In this paper, a compact-transmission-line (TL) decoupling and matching network (DMN) for three-element circular arrays is presented. As result of the miniaturization wireless terminals, antenna spacing too close, leading to large couplings deteriorating system performance. The DMN consists an impedance transformation section star-shaped neutralization which eliminates between antennas while oc...

A highly miniaturized 3-D spherical folded dipole antenna has been reported, for which inherent impedance matching is achieved with respect to a practical source by employing simple series– $LC$ loading combination, thereby engineerin...

Radar electronics developed for past JPL space missions historically had been custom designed and as such, given budgetary, time, and risk constraints, had not been optimized for maximum flexibility or miniaturization. To help reduce cost and risk of future radar missions, a “generic” radar module was conceived. The module includes a 1.25-GHz (L-band) transceiver and incorporates miniature high...

This paper initially presents an overview of different miniaturization techniques used for size reduction printed log-periodic dipole array (PLPDA) antennas, and then continues by presenting a design conventional PLPDA that operates from 0.7–8 GHz achieves realized gain around 5.5 dBi in most its bandwidth. antenna is as baseline model to implement novel technique extend the low-frequency respo...
