Microstrip Patch Antenna Array on Ground with Circular Pbg

In this paper, a microstrip patch antenna array on ground with PBG is simulated and measured. It is shown that the photonic band-gap (PBG) can suppress harmonics and optimize the current distribution on the patches. As a result, the gain of the antenna array is improved and the side-lobe level is reduced. © 2004 Wiley Periodicals, Inc. Microwave Opt Technol Lett 41: 127–130, 2004; Published onl...

A CPW-Fed Dual-Band Slot Antenna with Circular Polarization

In this paper, a coplanar waveguide (CPW)-fed dual-band slot antenna with circular polarization (CP) is presented. In order to achieve CP characteristic, an asymmetric slot and F-shaped end patch are introduced to a conventional rectangular slot antenna. Moreover, by cutting a T-shaped notch on the ground plane, the axial ratio (AR) bandwidth (ARBW) can be extended. The antenna shows left-hand ...

A Broadband Suspended Microstrip Antenna for Circular Polarization

In this paper we propose a circularly polarized (CP) microstrip antenna on a suspended substrate with a coplanar capacitive feed and a slot within the rectangular patch. The antenna has an axial ratio bandwidth (< 3 dB) of 7.1%. The proposed antenna exhibits a much higher impedance bandwidth of about 49% (S11 < −10 dB) and also yields return loss better than −15 dB in the useful range of circul...

Circular Patch Microstrip Array Antenna for KU-band

This paper present a circular patch microstrip array antenna operate in KU-band (10.9GHz – 17.25GHz). The proposed circular patch array antenna will be in light weight, flexible, slim and compact unit compare with current antenna used in KU-band. The paper also presents the detail steps of designing the circular patch microstrip array antenna. An Advance Design System (ADS) software is used to ...
