“…The dumbbell-shaped defected ground structure (DGS) cell effect on the dimension of MSA was presented by Arya et al and the cavity backed model was utilized in order to enhance the antenna efficiency [13]. The slotted H antenna with a modified ground plane has been designed and analysed by Razali et al for WiMAX application (2.45 GHz) [14]. The ground perturbation and ground dimension reduction by introducing a slot to enhance the bandwidth has been presented earlier [15].…”

The consequence of reduced ground plane in a coaxially-fed hexagonal antenna, on impedance and radiation is analyzed and presented here. Measured and simulated impedance results for a designed antenna are compared with the equivalent circuit model in this paper. The reduction in ground plane excited frequencies in upper C-band and lower X-band. The designed hexagonal antenna uses a substrate with a dimension of 32×33.5 mm2 along with a reduced ground plane of area, 10.44×24.44 mm2. The proposed antenna has a 285 MHz and 380 MHz impedance bandwidth in C-band and X-band respectively. The designed antenna with reduced ground plane works well for C-band and X-band applications.

“…Continuous developments in the field of wireless communication require a high performance antenna to fulfill the demand of such wireless systems (Eibert & Volakis,2007;Najeeb et al,2016). In recent years,Microstrip antenna draws much attention and have been developed by researchers, to meet the requirements, due to their advantages like low profile, small size, low cost (Yang et al,2008).patch shape modification (Razali et al, 2015). However, conventional microstrip antennas suffers from some limitations such as narrow bandwidth and low gain.…”

A new configuration of a Microstrip patch antenna array is presented in this paper. The array is arranged in such a way that only one patch placed in the E-plane and four patches are placed in the H-plane. This is to make the antenna provide a dual band performance and increase the gain. The feeding network utilized in the array is based on the step-loaded matching structure in order to maintain good matching impedance between the input port and the radiation (out) ports. The antenna arra y is simulated using the Computer Simulation Technology (CST) Microwave Studio. The gain of the first frequency band, which has the center frequency 4.35 GHz, is 8 dBi, while the second band is 5.8 dBi at the center frequency 9.8 GHz. Due to simplicity and high gain, the antenna array is of interest of many high gain and long distance applications such as point-to-point communication systems.
