A 4 × 2 Microstrip Patch Array Antenna for Gain Enhancement Using Both-Sided Microwave Integrated Circuit (MIC) Technology

To enhance gain performance using both-sided MIC technology, a 4×2 microstrip patch array antenna is constructed and simulated in this study. The antenna is constructed with a 2 × 2 array on each side and symmetric patches around the central feed line using a microstrip line feeding technique on a Teflon Glass Fiber substrate. The proposed antenna has a very high gain of 16.12 dBi at the operating frequency of 10.24 GHz, and the return loss value of -25 dB shows impedance matching. The antenna is correctly oriented in the broadside direction and has a 3 dB beamwidth of 60° in the Φ = 90° plane as well as 30° along Φ = 0° plane cut. The antenna has a radiation efficiency of 97% at the resonance frequency. The broadside direction gain for the antenna is 32 dB.
