A Broadband Monopole using LTCC Technology for WLAN Applications

Abstract

In this paper an orthogonal ground plane triangular monopole (OGP-TM) has been designed and measured. The OGP-TM uses a low loss, high permittivity substrate to achieve a bandwidth of 1.14 GHz from 4.5 GHz to 5.64 GHz. Small parasitic elements are used to tune the performance of the antenna. Measurements indicate a gain of 0 dB and a monopole-like radiation pattern. This work shows that broadband antennas can be designed using very high permittivity substrates. This is believed to be the first report of a compact and broadband OGP-TM antenna implemented on a LTCC substrate with er=68. The characteristics of this antenna make it suitable for many wireless local area network applications.
