A tree house shape microstrip patch antenna for multi-band applications

This paper, a novel design of Microstrip antenna with multi band of operation has been presented for wireless communications. This antenna is very distinctive in shape and has been fed through 50Ω coaxial feed line. The Beauty of the antenna lies in four band, S11≤ (-10) dB for 2.06 GHz, 10.92 GHz, 16.30 GHz and 24.24 GHz with a simulated gain of 6.2572 dB, 5.2190 dB, 6.9254 dB, 5.1175 dB and 6.3533 dB respectively. These results were taken by Ansoft HFSS (High Frequency Structural Simulator) Software. A U-shape cut on the feed patch Line, staircase in the bottom of patch structure and a small rectangular cut on top middle portion of the ground structure has been introduced in the proposed antenna. Size of proposed antenna is 30 × 32 × 1.6 mm
