Abstract

A microstrip leaky‐wave antenna (MLWA) with parasitic elements is presented in this letter. The short MLWA is the basic element, and two microstrip patches with a short‐circuit edge worked as the parasitic elements. The main lobe scans from 66° to 42° when operating frequency increases from 5.9 to 6.9 GHz. In contrast to the conventional MLWA, the reflected wave of the short MLWA (about two wavelengths) with parasitic elements is suppressed 12 dB at 6.9 GHz. © 2008 Wiley Periodicals, Inc.

## Abstract A beam‐patterns switchable microstrip leaky‐wave antenna (MLWA) is presented in this letter. A new feeding configuration of MLWA has been shown. MLWA fed with two feeding terminals on different sides radiates out single‐beam radiation patterns. Through controlling SPDT switch, the beam‐

Formulas based on the two-slot, the ca¨ity, and the surface current models to compute the far-field radiation patterns in both the E and H planes for rectangular microstrip antenna elements are studied and their ¨alidity assessed. Three closed-form formulas are presented for the calculation of the r
