A novel microstrip fed circular patch antenna with band notches for Bluetooth/UWB/X-band and Ku band applications

In this paper a novel microstrip fed circular patch antenna is analyzed in details for applications in Bluetooth, UWB, X-band and Ku band respectively. The basic antenna structure is a circular patch which is modified by adding complementary circular split ring resonators and T strip connected to the top of the patch. The antenna is fed by a 50 ohm microstrip feed line. A slot of dimension 2×3.6 mm² is inserted in the ground plane which consists of a staircase structure having appropriate dimensions. The ground is later modified with meander shaped slots for Bluetooth, X band and Ku band applications. The characteristics of the proposed antenna is carried out in HFSS 2013.
