This paper designs and simulates frequency reconfigurable microstrip patch antenna using Defected Ground Structures (DGS) with aperture coupled feed line. Single element with two regular slots etched on the ground layer has been designed to represent two resonant frequency 7.5 GHz and 8.85 GHz. Comparison two antenna designs without and with DGS structure is reported in this paper. Simulated results...
This paper presents the frequency reconfigurable antenna that can be applied either in LTE (2.6 GHz) or WiMAX (3.5 GHz) applications. This antenna is designed with a combination of an aperture coupled as the feeding technique and stacked patch technology or known as a Frequency Reconfigurable Stacked Patch Microstrip Antenna (FRSPMA). It consists of three substrates layers where all the layers are...
A novel design of frequency reconfigurable microstrip array antenna (FRMAA) using aperture coupler feeding technique is presented. In contrast with conventional antennas that can be operated at one frequency in a single antenna, this FRMAA is capable to operate at two different frequencies. In this paper, the ground plane which is located in the middle of the two substrates serves as a very effective...
This paper presents a novel design of a Frequency Reconfigurable Stacked Patch Microstrip Antenna (FRSPMA) by using an aperture coupler as the feeding technique and stacked technology. The proposed antenna was capable to accommodate at S/X band separately by using the same antenna. Two patches at different substrate are activated sequentially by changing the switch mode at the feedline to achieve...
