Wideband L-Probe Fed Inverted Hybrid E-H Microstrip Patch Antennas For IMT-2000 Band

Abstract

This Paper Presents A Novel Wideband L-Probe Fed Inverted Hybrid E-H Shaped Microstrip Patch Antenna (LIEH) Covering The International Mobile Telecommunications - 2000 (IMT-2000) Band. The Design Adopts Contemporary Techniques; L-Probe Feeding, Inverted Patch Structure With Air-Filled Dielectric, And Slotted Patch. The Composite Effect Of Integrating These Techniques And Introducing The Novel E-H Patch Shaped Offers A Low Profile, Broadband, High Gain, Low Crosspolarization, And Compact Antenna Element. Measurement Result Showed Satisfactory Performance With An Achievable Bandwidth Of 17.20% At 14 Db Return Loss (SWR = 1.5), Maximum Achievable Gain Of 8 Dbi With 1 Db Gain Variations, And Crosspolarization Level Of 23 Db Below The Main Lobe Level. The LIEH Patch Has A Compact Dimension Of 79 × 41 Mm2. The Design Is Suitable For Array Applications Especially For IMT-2000 Base Station Antenna.
