“…Hence, CP signals can still be obtained with minimal signal loss making them an ideal approach when the antenna rotation is relative among each other. There are different methods to excite orthogonal modes, such as singlefeed slotted square patch, truncated corners patch coaxial-feed, single truncated corner patch with inset feed, circular patch with unequal X-slit, microstrip feed stacked patch configuration and sequential rotation technique with 4-elements truncated subarray, as discussed in literature [13], [14], [15], [16], [17],…”

This research proposes a high performance, low-profile planar design, and demonstration of circularly polarized harmonic antenna arrays for 4 and 8 GHz harmonic radar system which is equipped, and the antenna's circular polarization performance is tested using a passive non-linear harmonic tag (snowflake) in a noisy environment. This work mainly concentrates on investigation of the wave polarization (Circular), gain estimation and impedance matching of the antenna arrays that will be potentially assembled to the 2 nd order harmonic radar system operating at 4 and 8 GHz, which plays a critical role in 2-D tag localization and post processing methods. The passive snowflake tag design is implemented in the simulation to determine the current distribution and gain plot patterns in comparison to a classic dipole antenna tag structure. In experiments: a combination of fundamental circular polarized (Left-hand) antennas were demonstrated to find Axial Ratio (A.R.) ≤ 3 dB band. A novel tag 2-D localization measurement, combination of CP harmonic antenna arrays is utilized to perform and obtain the circular polarized received signal power in dBm v/s angle rotation by every 10° on a rotating platform setup. Finally, the wireless tag tracking result is achieved by using the designed circularly polarized antennas and the passive non-linear tag orientation setup.

“…The purity of circular polarization is measured by cross-polarization. There are several techniques used for that like single feed configuration, double feed and multiple feed configuration is explained [12][13][14][15][16][17] . A dual circular polarization approach is used in the antenna for the right-and left-handed circular polarizations [18][19][20][21][22][23] .…”

<p class="abstract">Today is a generation of the satellite navigation system and every country needs its own positioning and secured services. GPS invention has given birth to a new era in technology. India in terms of population is highly dense and should have its own navigation system. High-level research is still going on for Navigation with Indian Constellation (NavIC) the Indian Regional Navigation Satellite System (IRNSS) to be developed for the frequency band L-band (1176.45MHz) and S-band (2492.08 MHz). In this paper, we summarize the attributes characterizing the NavIC antenna which includes patch size, polarization, Fractal attributes, etc. Similarly, the paper gives technical inputs to develop a compact and efficient NavIC antenna system for future L-band and S-band.</p>

“…3,4 It also reduces multipath fading and consumes lesser power. 5,6 Apart from these challenges, with the compactness in recent wireless devices, antenna miniaturization along with commercially acceptable gain [7][8][9] and multiband performance covering various wireless standards simultaneously is also of great interest. [10][11][12] In regard to this, literature reports numerous MIMO antennas.…”

In this paper, a miniaturized (12 × 20 × 1.6 mm3) dual antenna suitable for compact devices with multiple‐input multiple‐output (MIMO) applications have been designed, analyzed, and fabricated. The proposed design is printed on the single side of the FR4 substrate with a common ground and branched radiating structure. The branched structure is responsible in attaining 93.5% miniaturization as compared to the conventional size at 2.4 GHz (ie, lower resonance). Triple‐band characteristics have been extracted from port 1 (2.4, 3.5, and 4.5 GHz) and dual‐band characteristics from port 2 (2.4 and 3.5 GHz). The isolation between the radiating strips is better than 10 dB and the envelope correlation coefficient is less than 0.5. The proposed design has good isolation characteristics with acceptable peak gain of −1.75/1.3/2 dBi at 2.4/3.5/4.5 GHz, respectively. Good impedance matching and stable radiation patterns make the proposed antenna suitable for WLAN, WiMAX, and Indian National Satellite System applications.
