摘要

A cavity-backed antenna with low-profile, dual-polarization, and wide operatingrnbandwidth characteristics is proposed. In this design, two orthogonally positioned triangularrnbowtie antennas printed on a low-cost substrate are loaded onto a square cavity, sornthat two orthogonal linear polarizations can be excited. By further introducing four extendedrnground stubs from each side of the square cavity, the proposed antenna can also acquirernlow-profile characteristic of approximately 0.1λ(15 mm). To achieve good impedancernmatching, additional circular slots are introduced into each bowtie design. The measuredrnresults show that the proposed antenna can cover a wide operating bandwidth of 62% (2.0–rn3.8 GHz) with a VSWR of 2:1. Besides exhibiting good isolation (>20 dB) between the twornfeeding ports, desirable realized gains (6.0–10.5 dBi) over the wide operation band are alsorndemonstrated.
