Abstract

A compact DVB‐H (digital video broadcasting—Handheld) Marchand balun using coplanar waveguide (CPW) coupling structure is presented.The proposed structure combines a double sided meandered CPW Marchand structure with lumped elements. Having the vertical coupling of meandered CPW Marchand structure, wide bandwidth for DVB‐H band (470–710 MHz) is achieved. Also, lumped elements are used to reduce the physical length of the coupling meandered lines. The proposed DVB‐H balun is fabricated on FR‐4 board and both simulated and measured results are presented to illustrate its performance. © 2010 Wiley Periodicals, Inc.

## Abstract In this paper, a broadband microstrip Marchand balun is presented. It is implemented by new vertical coupled structure, which is suggested to improve the coupling effect in the conventional coupler. Using this vertical coupling structure, the Marchand balun shows broad bandwidth of larg
