A Review Analysis on Microstrip Patch Antenna

This article presents the general overview of various antennas and a detailed study of Microstrip Antenna (MPA). The MPA designing equations and basic structure is explained in this manuscript. The properties of the materials required for MPA is summarized in table form. Some practical antenna structures are also explained here in order to analyze the overall view of MPAs after explanation of most common patch structure shapes. At last, the properties of Co-axial, Proximity Coupling, Aperture Coupling and stripline feeding are also introduce in terms of ease of fabrication, impedance, modelling, bandwidth etc.

Aperture coupling rectangular slotted circular ring microstrip patch antenna

<p>This paper designed circular ring microstrip patch antenna using aperture coupling feeding techniques with rectangular slots on the patch for LTE. The use of aperture coupling feeding techniques were expected to optimize antenna parameters performance. The addition of rectangular slots on the patch produced multi resonant frequencies than the original characteristics. The simulated optimized design generated 1.8 GHz, 2.1 GHz, and 2.72 GHz with Return Loss value -22.3683 dB, -18.8133 dB, -24.3451 dB and VSWR value 1.1648, 1.259, 1.1291. Meanwhile, the measurement results of fabricated antenna showed the frequency produced by the antenna was 1.8 GHz with value of Return Loss and VSWR -18.257 dB and 1.278 in a reference value of VSWR &lt; 2 and Return Loss &lt; -10 dB.</p>
