Abstract

A wideband correlator, with 45% relative bandwidth is proposed at the frequency range of 3.0–5.1 GHz. The structures of the correlator components such as the delay line and the Wilkinson power divider are designed to be realized in transmission line using the Agilent's Advanced Design System. The correlator made by using three unique wideband 3‐dB couplers, rat‐race coupler, and one 3‐dB Wilkinson power divider to reach the required bandwidth. The insertion loss, amplitude imbalance, and phase imbalance between ports are presented. The proposed correlator makes compact size better than correlator of conventional structure.

## Abstract A simple compact microstrip rat‐race ring coupler with capacitor loading is presented in this letter. The new coupler not only effectively reduces the occupied area to 15% of the conventional one at 1.0 GHz, but also has high harmonic suppression performance over a wide band. Furthermor

## Abstract A conventional rat‐race coupler has been doubly miniaturized: (i) characteristic impedances and electrical lengths of microstrip sections have been adequately modified as the first step of size reduction and (ii) T‐shaped PBG cells have been implemented to diminish strip section length
