Abstract

This Letter describes a slot loop antenna that is partially short circuited in order to create beam tilt in the far‐field radiation for the purpose of reduced SAR. Here the characteristics of a partly shorted slot loop constructed on low‐dielectric‐constant PCB material, ε~r~ = 2.33 designed to operate at 2400 MHz are illustrated. The loop is fed from a microstrip line, removing the requirement for the balun feed arrangement normally required for loop antennas. The resulting antenna exhibits a 30° beam tilt and has an estimated gain of 6 dBi. © 2002 Wiley Periodicals, Inc.

## Abstract A design method for DBS‐TV reception antennas with tilted beam using a radial feed line with a slot radiating array is proposed. A cylindrical TEM wave excites the slots and must be placed eccentrically in order to produce a tilted beam. The proposed design method allows us to obtain go

## Abstract A printed square slot loop antenna capable of radiating slant 45‐degree polarized signals over a wideband is presented. A radial wideband stub feeds the square slot loop at the diagonal and the antenna exhibits an impedance and radiation bandwidth of more than octaveband (1.7 to 3.5 GHz
