The microstrip patch antenna is now very famous due to its compact size, good gain and directivity bandwidth is mostly not very good in microstrip patch antenna but in this paper bandwidth of the ...

Helical antennas, another common design, yield a precision of at least 5 mm. They are taller than patch antennas, with a coil of four metallic elements pointing upwards. A key advantage is that ...

4. Shown is an 8 × 16 patch-antenna array (128-element) with corporate feed (single-feed port) and 167 k unknowns (1.88 GHz) solved in approximately 6.5 minutes with quad core.
