Frequency Reconfigurable Microstrip Circular Patch Antenna for Wireless Devices

In this paper, a frequency reconfigurable circular antenna design and development is proposed for wireless devices. In the proposed design, a circular patch antenna with circular slot using two PIN diodes at the centre frequency 10 GHz was designed and simulated frequency reconfiguration is achieved in the frequency range of 9.69-10.2 GHz and the measured results shows the same effect in the fr...

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...

Reconfigurable Microstrip Patch Antenna for Frequency Diversity Using RF MEMS

Abstract: A novel reconfigurable patch antenna for frequency diversity is proposed by reconfiguring its geometry using tree rectangular tapes that are connected to the patch via six RF MEMS switches. So switching between the different frequency bands is achieved by using capacitive series RF-MEMS switches. The antenna was designed to operate at 2.6 GHz, 3.1 GHz, 3.5 GHz and 5 GHz.

Frequency-Reconfigurable Stacked Patch Microstrip Antenna Using Aperture-Coupled Technique

This paper presents a novel structure of a frequency-reconfigurable microstrip antenna fed with an aperture-coupled technique and stacked patch technology. The proposed antenna design has a unique structure; the radiating elements (top and bottom patch) are sorted in stacked substrate layers to indicate the different operating frequencies. One PIN diode switch integrated at the feedline is reco...
