A Compact Hybrid Multiband Antenna for Wireless Applications

This paper presents design of Compact Hybrid Multiband Antenna (CHMA) for various wireless applications. The projected antenna geometry is designed by integrating moore and gosper curves and their characteristics are investigated. The antenna reveals multiband behavior along with satisfactory values of all performance parameters in spite of less complexity and compact size. The small cost simulated antenna is designed on FR4 substrate, which shows gain of 16.65 dB along with return loss of -18.39 dB and VSWR of 1.27 at 2.4 GHz frequency. Simulated results exhibits six operational bands that cover various significant frequency bands like Air traffic control RADAR (0.96-1.215 GHz), GSM (1.85-1.99 GHz), Wi-Fi (2.4 GHz for 802.11b, 802.11n and 802.11g), WLAN 802.11a/b (5.15-5.35 GHz), WLAN 802.11ac (5.5 GHz) and military satellite applications (7.9-8.4 GHz). The simulation results of antenna in terms of antenna parameters like Return Loss (RL), radiation pattern, Voltage Standing Wave Ratio (VSWR) and Gain (G) are evaluated using HFSS (High Frequency Structural Simulator); v13 software. The hybrid antenna is designed with line feed having compact size of 55 mm (L) x 60 mm (W) x 1.6 mm (H) on FR4_epoxy substrate with epsilon(r) 4.4. Both simulated and measured results are analyzed, compared and presented in the paper. Proposed antenna operates from 0.98 to 8.1 GHz and covers L, S, C and X band applications.
