1 Indian Journal of Radio & Space Physics Vol. 34, December 25, pp Analysis of slot-loaded rectangular microstrip patch antenna Shivnarayan, Shashank Sharma & Babau R Vishvakarma Department of Electronics Engineering, Institute of Technology, Banaras Hindu University, Varanasi 221 5, Indi a Received 23 November 24; revised 17 February 25: accepted 21 Apri/25 In the present paper, the analysis of a slot-loaded rectangular microstrip patch antenna using equivalent circuit concept is presented. The slot is taken as a capacitive reactance on the patch. It is found that the resonance frequency decreases with increasing slot width for a given slot length. The decrease in the resonance frequency is in the higher side for longer slot length, as it is on the minimum side for the lower slot length. It is found that VSWR remains almost invariant with slot width and slot length. The impedance increases almost linearly with the slot width, but inversely with the slot length. Keywords: Slot-loaded patch, Rectangular microstrip antenna, Microstrip antenna PACS No.: 84.4 Ba IPC Code: HOIQ9/; HOIQ2!/; HO!Q23/ 1 Introduction Narrow bandwidth is the major disadvantage of microstrip antenna in practical applications. For present day wireless communication systems, the required operating bandwidth for antennas 1 is about 7.6% for a global system for mobile communication, 9.5% for a digital communication system and 12.2% for universal mobile telecommunication system. Several bandwidth enhancement or broadbanding techniques are recently employed, such as coplanar directly gap-coupled patches 2, use of a thick air or foam substrate 3, etc. It may be mentioned that bandwidth can also be improved by loadin? of suitable slots along the radiating edges of patch 4 '. By embedding suitable slots in the radiating patch 6, compact and dual band rnicrostrip antennas 7 ' 8 can be realized. Multiple slots are also used to control the impedance 9 of the rnicrostrip antennas. These days, many methods such as FDTD method 1 and Hybrid multi port theor/ 1, etc. are used for the analysis of slot-loaded rnicrostrip antenna. This paper presents the analysis of a slot-loaded rectangular microstrip antenna (Fig. 1) using equivalent circuit concept in which patch and slot on the patch are represented in terms of equivalent circuit parameters. In this circuit the slot is taken as a capacitive reactance on the patch to counteract the inductive reactance of the probe 12 It may be added that the analysis of slot on the patch has been done by usin duality relationship between the dipole and sld. The aim of the work is to study the effect of narrow slot on the performance of the rectangular rnicrostrip antenna such as input impedance, VSWR and return loss. 2 Theoretical considerations Slot on the patch can be analyzed by using the duality relationship between the dipole and the slot.

Since the slot is thin, the voltage can be sinusoidal with zero voltage across the ends of slot.

It is observed that the resonance frequency decreases with increasing slot width for a given slot length. A similar result has been also reported by Fan Yang 16. The range of frequency variation with slot width for a given slot length is found to be maximum (.4 GHz) for the lowest slot length (L,=l6 mm), as it is minimum (.16 GHz) for the largest slot length (L,=3 mm). It is important to note that there is a significant change in resonance frequency with the slot on the patch as compared to patch without slot.

Note: In the case of without slot, the % bandwidth is for all cases (slot widths) The variation in the resonance frequency with slot width is attributed to the fact that increasing dimension of the slot modifies the effective values of capacitive reactance, which renders the change in the resonance frequency. The variation of VSWR with frequency for different slot width and slot length is shown in Fig. 4. It is found that the resonance frequency decreases with increasing slot width for a given slot length. The decrement occurs in resonance frequency, i.e % for L, = 16 mm and.59% for L, = (26-3 mm) with the variation of slot width. This is also corroborated from Fig. 6. It may be noted that the decrease in the resonance frequency is on the higher side for higher slot length, as it is on the lower side for the lower slot length. Further, it may be noted that the change in the resonance frequency is minimum (.16 GHz) for the longest slot length (3 mm), as it is maximum (.4 GHz) for the minimum slot length (16 mm). This is also corroborated from return loss data shown in Fig. 5. The variation of VSWR with slot width for different slot length is shown in Fig. 7. It is observed that the value of VSWR remains around 1.3 for different slot widths and slot lengths which is slightly higher as compared to the value for patch without slot, i.e The variation of real part of input impedance with slot width for a given slot length is shown in Fig. 8. It is found that the real part of the input impedance at resonance increases minutely with increasing slot width for all slot lengths considered. However, it may be noted that the values are slightly higher with
7 43 INDIAN J RADIO & SPACE PHYS, DECEMBER 25 decreasing slot length. From Fig. 8, it is also observed that the real part of input impedance increases almost linearly with slot width but inversely with the slot length. 7 Conclusions It may be concluded that loading of patch with narrow slot. affects significantly the resonance frequency, input impedance and bandwidth increase with slot width for a given slot length (Table 1 ).
