This paper presents a novel of a Reconfigurable Stacked Patch Microstrip Array Antenna (RSPMAA) integrated with radio frequency (RF) switches at the feedline. The antenna uses a combination of aperture coupled technique and stacked patch technology for reducing spurious radiation patterns. Generally, this RSPMAA consist of three substrate layers (RT-Rogers 5880) and an air filled substrate between...
This paper presents a novel structure of reconfigurable microstrip patch antenna by using aperture-coupled feeding technique. The proposed antenna design has a rhombus-like patch shape embedded with unique patch slots and truncated edges. In contrast with conventional antennas which operate at one frequency with one beam direction in a single antenna, this reconfigurable antenna is able to operate...
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...
