The branch-line coupler (BLC) is an important device in radio frequency (RF) and
microwave (MW) circuits. The main drawbacks of the conventional BLC are as follows: first …

This article presents a Mid-section crossed dual-band Branch-Line Coupler (MBLC) with
port extensions, along with a new design methodology for both complex and conventional …

A novel quasi-twisted miniaturized wideband branch line coupler (BLC) is proposed. The
design is based on bisecting the conventional microstrip line BLC transversely and folding …

Power dividers are the most important tools in microwave systems such as mixers, frequency
multipliers, and feeding networks in antennas. So far, in designing power dividers, various …

In this article, a new method is presented to calculate dimensions of a hexagonal-shaped
antenna based on frequency and rectangular-shaped antenna. The frequency responses of …

In this paper, a novel miniaturized wideband planar bow‐tie slot antenna is proposed. For
the purpose of miniaturization and wide bandwidth, the effects of the dimension and shape …

This paper deals with the design of a prototype microstrip filter, which would be suitable for
integration into active phased array antennas. This novel compact microstrip lowpass filter is …
