Design of a Compact Circular Patch Antenna Operating at ISM-Band for the WiMAX Communication Systems

Efficient 5.8 GHz Microstrip Antennas for Intelligent Transportation Systems: Design, Fabrication, and Performance Analysis

“…Return loss is a critical parameter in antenna applications, serving as a measure of how much power applied to the input port is reflected. It plays a pivotal role in assessing input port impedance mismatch and determining the operating frequency range of the antenna [28]. In our study, the antennas designed in different simulation environments exhibit distinct bandwidths and center frequencies.…”

The Development of Broadband Microstrip Patch Antenna for Wireless Applications

“…In another study, an antenna design with a circular patch fed by a microstrip line operates at a frequency of 2.49 GHz. It has achieved a bandwidth of 80 MHz and a directivity gain of 2.611 dBi [16]. Several methods have been introduced, such as using slits [17], slots [18], DGS (Defected Ground Structure) [19], partial ground plane [20][21], split-ring resonator [22], substrate integrated waveguide (SIW) [23], dielectric rezonator (DRA) [24], using air gap [25], shorting pin [26] and using EBG (Electromagnetic Band Gap) structures [27].…”

Although there are many studies in the literature to increase the bandwidth, the easiest way to increase the bandwidth is to use slots in the patch plane and make changes in the ground plane [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. This paper presents the design of a slotted microstrip patch antenna operating in the ISM 2.4 GHz band (2400-2485 MHz).…”
