“…The contemporary fourth generation (4G) wireless communication systems and antennas used in several countries around the world can no longer cater for some challenges such as endless need for high data rates, low gain, and flexibility requirement by modern wireless devices and applications. These challenges are imposed mainly by the outburst of wireless devices and services .…”

A compact grid array antenna implemented using FR4 substrate for 5G Mobile Communications at 15 GHz is presented. The antenna with dimensions of 49 mm × 58 mm × 1.6 mm has 23 radiating elements to provide high gain. It is excited using coaxial feeding technique. Measurement of the fabricated prototype for the simulated antenna was carried out. Both measured and simulated results agree with each other. The measured result shows that the antenna has achieved an impedance bandwidth of 14% from 13.8 GHz to 15.9 GHz with a gain of 14.4 dBi at 15.9 GHz. © 2016 Wiley Periodicals, Inc.

“…The growing demands for greater capacities, broadband service, and communication speeds to transmit data in embedded system like mobile phone [1], security [2] and RFID systems [3] has imposed working on new types of antennas. In order to respond to these new constraints, these antennas should be wideband, or multiband and embedded to all types of environments.…”

network in which two low-frequency (LF) signals are subtracted allows to minimize losses, as LF signal is virtually not subject to dielectric absorption and parasitic radiation. Furthermore, the presented solution does not use any LF fixed phase shifters which cause significant difficulties in wideband systems. As a result, 15% shortening of the microwave signal path has been achieved in the presented receiver. Figure 8 presents the measured radiation pattern of the developed radar receiver. As it is seen, the obtained beams measured at intermediate frequency f 5 10 MHz are in close agreement with the ones presented in Figures 2 and 4, although minor asymmetry between L and R beams can be seen, which is caused by imbalance of mixers' characteristics, mainly the input impedance. The gain and the losses of the receiver's antenna array could not be precisely measured due to uncertainty of the mixers' conversion gain. However, the receiver's antenna gain and the losses can be estimated from the fact that the receiver's feeding network is 15% shorter than feeding network of the antenna from Figure 1. Hence the gain equal 7.4 dBi and the insertion losses equal 1.8 dB have been estimated. The manufactured receiver is shown in Figure 9. CONCLUSIONA novel concept of the switched-beam antenna array with broadside beam has been presented. The proposed antenna array utilizes a modified Butler matrix as a feeding network and allows for achieving two symmetrically placed beams and a broadside beam. Moreover, the proposed network rearrangement allows for fully planar realization without the need of transmission line crossovers. The developed concept has been applied in a Doppler radar receiver, in which a low frequency differential amplifier has substituted the RF power divider and a constant 180 phase shifter, minimizing the dissipation losses and parasitic radiation of the feeding network. The proposed concept of a switched-beam antenna has been verified experimentally. The obtained measurement results fully confirm the theoretical predictions. ACKNOWLEDGMENT
