Broadband E‐shaped microstrip antenna with dipole RE‐radiators

Abstract

New design of microstrip patch antenna with coaxial feed is proposed in this article. The proposed construction includes additional dipole radiators placed over main patch and exhibits enhanced broadbandness comparing to classical E‐shaped patch antenna. Also, gain of proposed antenna is highly stable in the broad frequency band. © 2012 Wiley Periodicals, Inc.

Vivaldi antenna with printed lens in aperture

“…Vivaldi antennas are widely used in various radio systems, including—UWB systems, due to ease of implementation by technology of printed circuit boards . Vivaldi antennas are very useful in the arrays, even very frequent, because concentration of electric field lines in space adjacent to the slot can significantly reduce degree of coupling between adjacent antenna elements . A common disadvantage of various modifications of Vivaldi antennas, inherent to all traveling‐wave antennas, is high level of side lobes, especially noticeable in the E‐plane.…”

Analysis of Broadband E-shaped Microstrip Antennas

“…As against the equal lengths of pair of rectangular slots in E-shaped MSA, pair of unequal length slots were used. The BW of E-shaped MSA has been increased by stacking two dipole re-radiators above the E-shaped patch which yields stable gain of around 8.4 -8.7 dBi [11]. Using the circuit theory approach, an analysis of E-shaped MSA is reported [12].…”
